My Very First Fluid Sim in Houdini (1 hour build time, 7 hours Render)

[Greyh0und]

Hey Applesoldier, would you mind sharing the source (3ds max / some kind of file)?

[AppleSoldier]

email?

[zelcom]

Hmm, I hope not this is the best fluid sim that houdini is capable of doing, because this was a bit disappointing :-/

Doesn´t look like how fluids flow at all.

[Anon4427]

Houdini can do far better, it's just that Eric brought a Mac, meaning he got lower specifications for his cash. To do realistic fluids takes quite a bit of processing power, it also doesn't help that the renderer in Houdini is quite inefficient, this means that for the same processing power other apps like Blender, Cinema 4D, 3DS max and Maya could do better. However Max, Maya and C4d rely on external apps like glu and realflow.

[RenegadeMaster07]

nice work.

Digital Tutors are the way to go.

[LetsPlayGmod]

I'm not gonna make a direct bash here, but Aussies video was way, way higher than 13 FPS.

[Whatevernever001]

hehe watch?v=jLDlXgfDYuw

[Fribarada]

Wow

Shitty

put in some more fucking effort you hick

[Anon4427]

If that took you an hour to build and 7 hours to render then you might want some different software.

C4D and Realflow could hammer out fluid that good in an hour on a low-mid range PC and given the same 7 hours could do something truly impressive. I would expect 2 minutes per frame if you had global illumination, realistic caustics and fresnel reflections but you don't appear to have any of those.

[PoliticalHell]

I don't get it, if you render this uncompressed in HD frame by frame it should NOT take 7 hours no matter how complex it is. That would mean every frame of this takes like 3-5 minutes to load, which is terrible. A good computer should be able to load even such a big image in seconds, and just compile them into a video, add compression if necessary.

[nemirc]

After doing some math, those 7 hours don't sound that unreal, although maybe you could drop it to 5 or 6 at the most by playing with the settings.

I also assume you used a cache. If houdini has a geometry cache you can use that as well.

On a side note, using a similar setup in mentalray should give you a little over 5 hours.

[HWGuyEG]

Heh, I could do the same thing in MAYA... no need to learn how to use another application.

Also... damn, 7 hours for 720p... that's brutal, someone needs to learn distributed computing... or get a faster box.

[AppleSoldier]

obviously you know DICK about rendering

[HWGuyEG]

Coming form the guy that just learnt how to fill a cup of goo...

I don't know what your setup is, but 168 frames(assuming 720p_24) only takes 4-5 hours on the average 2P Quad system.

Encoding the raw frames to video really isn't a factor if you have fast hardware, and storage.

"HD takes 4.5 times larger..." You lost me there...

DV is generally 480p = 0.3456 MP

HDV-720p is 0.9216 MP

HDV-1080i is 1.0368 MP (2.0736 MP when you interleave 2 frames)

But DV and HDV are a span of tape formats...

[AppleSoldier]

HD takes 4.5 times larger than a frame of DV. Every pixel has to go through the same process. There are other factors that make HD encoding slower (per pixel) than SD encoding. These is the complexity of MPEG encoding vs DV. Then there is the issue PC cache sizes. larger HDV frames are being processed in slower system memory vs the smaller DV frames which fit better in L2 cache. the 8:1 ratio measure is perfectly reasonable. This is why so many are upgrading their PCs , HD takes a lot of CPU.

[nemirc]

I don't know if I understood this correctly, but it sounds like you were rendering directly to video instead of using an image sequence?

[Winfanboy]

I'll give you 5 stars for effort.

[FLCProductions]

WOW! that is not craazy nut insain!!!!!!!

[masterd151]

If that took 7 hours to render then something was seriously wrong.

[thomashome05]

err it's because it's HD! Has the PC got HD yet?

[masterd151]

you obviously have no idea what youre talking about.

That should have rendered in 2.5 hours tops maybe 3.

[AppleSoldier]

Obviously you have no idea. Youhave one fucking video and you think we are to take your wrod? lol, 2 hours>?lol, you obviously dont have a clue about render fluids.

It would of been faster but when you add specularty, reflection, shadow, lights and rendering glass TAKES FOEVER or it looks fake, You have no fucking clue. Make a 3d fluids video or go be a 3d poser somewhere else MR " I know what im doing yet have no videos"

[AppleSoldier]

HD takes 4.5 times larger than a frame of DV. Every pixel has to go through the same process. There are other factors that make HD encoding slower (per pixel) than SD encoding.

[sNpeR1080]

aussie's animations shit all over yours.

[thomashome05]

Aussie's gay sex video's are not animations there real! (And yes that's Aussie doing his thing with another man)

[sNpeR1080]

typical emeek fanboy response.

[oOADROo]

7 hours!!!!!!!  to render that?? dude you need a PC. You will safe loads of time, trust me

[oOADROo]

sorry ment to say (save)

[thomashome05]

Dude you need a Mac you can actually make things worth looking at. God them videos you do are ugly! Do you have no taste?

[masterd151]

I hope this comment wasnt intended for me.

[oOADROo]

thomashome05 why are you stalking me . Are you a faggot or somfin? BTW this comment was to emeek, Now go stork some faggot Mac user

[thomashome05]

no rather stalk faggot pc users who cannot understand Windows 7 is just Vista with more jazz!

[ThingsontheWeb]

Vista is Windows 6, Windows 7 is based on the 2008 server kernel, with a re-written explorer. Added DX 11 and more we don't even know about becasue it's a BETA!.

How can you call anyone a faggot when you LOVE a fruit.

[thomashome05]

Well done Windows Vista is Windows NT Version 6 and Windows 7 has the kernel of Microsoft Windows Server 08 which is a optimized kernel for the enterprise unlike Apple who keep the OS relatively the same when it comes to the Server and Client. The Re Written Explorer must be great I mean it makes me so want to go Windows! DirectX sucks but so does OpenGL so no argument there.

[christheferal]

1 seconds footage took 1 hour to render??

that's (at 30 fps) 1 frame every 2 minutes. WOW!

What res did you export at!?!?

[AppleSoldier]

rendered at 1280x720 HD

[1xxxxxxdreamxxxxxx1]

that took an hour to build? jesus you must be new to this stuff.

[AppleSoldier]

yep, my very first time. And go get houdini the free version and show me you can do it quicker. I bet yu cant. Fluids ARE NOT like normal models

[blacksteel25]

I found one pretty amazing Blender video of a whale shark.

watch?v=q01Kjlw7tVw&feature=re­lated

He also has a few other video's, just some amazing stuff.

[AppleSoldier]

blender is good too

[VegasUndergroundLive]

I think it is out brazen of you to just start off the comments with "fuck maya", because we all know how you would react if the first comment were to be "fuck mac", but I digress.

Since you speak of this Application SO much, im going to pit it against Maya, since I have a year left in my license I can take time away from it to test what seems, like a fair competitor, well after reading some of their homepage anyway.

Also, excellent animation, can Houdini use Liquid to produce fire?

[AppleSoldier]

i only hate maya because of autodesk. They have ruined it. when it was Alias it was teh shit

[VegasUndergroundLive]

That I can fucking agree with.

[SantaClause49]

Realflow would be faster though.

[AppleSoldier]

maybe, depends

[iuzc]

macfixitforumsDOTcom

MacfixitDOTcom

[dannewashere]

does houdini do this with a particle system like realflow?

[AppleSoldier]

yes

[blacksteel25]

Yeah Blender does this and it's free...

[AppleSoldier]

blender fluids are NOT houdini. you say it is and lots think so but trust me, its not.

[AppleSoldier]

than go do it

[bryant1316]

I can do this in twenty minutes with my beowulf cluster of gaymen PCs.

[AppleSoldier]

lol

[oOTheAlchemistOo]

BOOOOO I seen aussie make cars move in blender on a gaming PC and this is the best you can come up with on that expensive mac pro?

[AppleSoldier]

make cars move? LOLOLOLOL, cars ARE NOT FLUIDS and if you dont know the difference your a noob

[oOTheAlchemistOo]

Still it took you 7 hours to make this? And yes I have seen fluid in Blender.

[AppleSoldier]

it didnt take 7 hours to make it took 7 hours to ender and it would take as long in blender for this also.

[AppleSoldier]

by the way.

[ThingsontheWeb]

Now your spamming your own videos. I'm going to ask you something I asked a while back .... Are you on drugs? You smoke alot in your videos and you sound like a crazy person most of the time. You also spit out videos on how your emotions feel that day. Get some help dude, it's not your fault, it's a disease

[oOTheAlchemistOo]

Check this out watch?v=WruTNnF6Ztg Totally pwns this bullshit and it was done in blender on a fucking PC. What do you have to say for yourself?

[AppleSoldier]

i can say i can link you to professional sims in houdini that kill that. This is my first sim dude, GET IT?

[oOTheAlchemistOo]

I an just fucking with you man

[AppleSoldier]

i know, busting my balls. I get it. Blender is good man.

[Hildron101010]

How did this take 7 hours to render on your Mac Pro?

[AppleSoldier]

fluids are massive. not like nodeling

[niveceritt]

Looks great, I can tell you put alot of work into it, don't listen to these cunts.

[AppleSoldier]

if it doesnt look like a real glass than there is no point. To an untrained person not looking they would say thats real.

[fegrad0]

THAT WAS GOOD

[Greyh0und]

7 seconds movie?

7 hours render time?

WTF?

Is it really THAT heavy or have you been rendering on some Pentium 3 piece of shit?

[AppleSoldier]

its really heavy. Fluids are not like regular geometry modeling. If this wasnt fluid it would of took about an hour. Plus reflections, shadows, spectrality. All has to be right or the glass looks fake. and glass takes forever to render compared to clay etc

[AppleGeneration]

hey emeek i dont understand why it would take seven hours

[AppleSoldier]

because rendering fluids in 1280x720 HD with reflections, shadows, and glass. And glass takes forever to render. If you dont get it right it looks fake. If this wasnt fluids, it would of been done in an hour or less

[ThingsontheWeb]

no sound, and looks like the liquid wasn't filling the cup properly.

2 stars, I give one when you talk about Windows, cause those are even worse then these kinds of videos

[AppleSoldier]

wow, rating video because of the owner not because of the content. WOW, your not a fanboy are you?

[dusthillguy]

I'm suprised this took 7 hours to render. It doesn't look much more advanced than an N64 game.

[AppleSoldier]

trust me, it is. Its not like rendering regular models etc. This is fluids rendered in 1280x720 with 3 lights and one environment light. Shadows, reflections etc. Its a huge task for any computer. mac or pc

[gaahhhhhh]

Lmao, funny how the video on the Mac Vs. PC account gets a 2.5 star rating and the exact same one on his non Mac Vs. PC gets a 5. Shows how many people actually rate his videos honestly.

I rated 5 stars btw. Really cool :)

[jase7725]

I like it ...very cool.

[LessthanJake14]

Wow, reminds me of....physics. You know, the type of physics you get from....physics programs.

[grapesofbaath]

this is amazing. you have a bright future ahead of you, young man. voted one out of jealousy of your immense talent.

[Horus998]

1 star, raging macfag multi account user, shitty animation that took 7 hours to make? holy fuck you suck

[Carloz800]

Horus988-

It's still better than thoes 2 videos you have with 2 and a half rating LOL

[TwistedShrapnel]

okay moron go and make one then if it's so~ easy.

[morsleyg]

7 hours for a 7 second animation?

Extremely basic refraction, no GI, not even any shadows.

My GPU could render this in real time, ffs, in fact the nVidia Phys-X demos look better than this.

Ive made animations of a few seconds long with full GI, physically accurite refractions with caustics and reflections that only took a couple of hours on a quad core PC using 3dstudio Max.

[aussie114]

agree with you 100% GPUs can render physics demos from nVidia that look better and are in real time.

[johnarkans]

Where's your video then Morsleyg?

Man, the internet is like a big steaming turd that attracts ignorant flies like Morsley.

[Larz9220]

apple soulja boy

[jmla113]

STOP FUCKING RATING EMEEK'S VIDEOS 1 STAR. Everyone who does that are just proving that they are all ignorant, useless fucks. I don't give a shit if you hate him, rate the video not the uploader all of you dumb assholes, suck a dick. 5 stars

[inyourcrawlspace]

Oh look it's emeek's first fluid sim lets put it on the fridge and slap a gold star on it. Get fucking real. Some people may vote it 1 because it looks bad and nothing to do with emeek being an idiot.

[AppleSoldier]

than show me how YOU can do it. I know this is good, its only your jealous. This is REALLY good for my first time. If it isnt than go get free houdini and show me how to do it better. I BET YOU CANT cause your have no clue. none of the people vote 1 because it looks bad. If you say it looks bad, the glas dont look real etc i know your a jealous Liar. I seen other sims on youtube. search fluid sim. I gues im not teh only one with work on the fridge

[inyourcrawlspace]

Sorry for having an opinion that differs from your own. Take a look at the background on my channel if you want to see something I made several years ago and I think that is pretty shitty too. What exactly am I jealous of though that you can go through some basic fluid sim tutorial? That procedural texture or whatever it is looks really bad too.

[sagethishit]

It's "you're", not "your". Stop doing that, it makes you look like a dumb person.

[Miisen]

Emeek is dyslectic, you should not make fun of him!

[AppleSoldier]

i may really be. think befor you speak.

[Miisen]

I know you are, It was not meant as an insult.

[ThingsontheWeb]

You do spell the word "THE" as "TEH" alot.

[aussie114]

lol, it should only take 7 hours if your animation is running at 300 frames per second which I highly doubt that, with no shadow or spec, can't tell if there are an reflective properties tho looks like transparency has just been turned on. and why would you use a saw marble texture sin would look way better with these colour property's main = R 0.400 G 0.420 B 0.350 secondary R 1.000 G 1.000 B 1.000 BTW I gave you 4 stars not one, don't be a stereotype

[AppleSoldier]

lol, once again, ass speak from someone who has NO 3D videos at all. Stop acting liek you know what your doing and go make a fluid sim. This was RENDEREDin HD 1280x720, not rendered in SD and encoded to HD, it was rendered in HD. Obviously you have no idea about 3d. Cause this render time is common.

[roxgod666]

I rendered a 6 minute video in HD 1280x720. It took about 2 hours for more than 6 minutes of HD so i think a 7 second video could do better.

[AppleSoldier]

you dont know what I included in the scene. I dont believe you did it, if so go get houdini and PROVE IT. This has shadows, specular, an envirment light, which is harder to render than spot or point. I also have 2 addiional spot lights The glass takes twice as long to render than normal surfaces and fluids are not like rendering geometry you say you did a video but IT WASNT FLUIDS. If this wasnt fluids id have it dont in an hour or less, ASS SPEAKER. everybody is an expert.

[ThingsontheWeb]

You stole the idea from the guy you are accusing has no 3D experience at all. You are truly pathetic emeek, LOSER

[AppleSoldier]

god your a noob. Do you see the water? lol, SHADOWS IS ON adn reflections are there. your just to inexperienced to see it. Specularity was set, gloss was set, reflection was set etc. Shadows are on, and teh original render was 3 times longer.

I used he marble because i like it. How it looks isnt right or wrong, its opinion. i think your all jealous. You all talk like your 3d arist but you dont even have a video if your work. and this was my first ever fluid sim.

[AppleSoldier]

if its so easy go get the free version of houdini and show me how its done ass speaker. lol.

[aussie114]

you think i'm jealous of a jug filling up with water, BAH, and considering my latest video is of 3D animation work that I have I think your the ass speaker. Blender OWNS Houdini on every level, I have multiple videos with fluid sims in them, the render in Houdini is just slow thats all there is too it. 7 hours to render piss in a cup lol.

[AppleSoldier]

you pc guys rate one star just because you dont like my mac vs pc videos, lol. Your only allowed to rate one star because I ALLOW YOU TOO. I could easily disable it but ill allow you to think your doing something. you do it cause i let you, no other reason.

[Miisen]

You said it yourself, they vote 1 because they don't like your videos.

1. Create a good video with good content

2. Do not lie and make up facts

3. Profit

What you are doing right now is going the wrong way Emeek. If you just try harder next time the feedback will be better!

[AppleSoldier]

this video isnt a lie or made up. This is proof you rate based on the user not the video content. It shouldnt matter who posts it this isnt mac vs pc. And ill do as I like, Like i said, ill disable it before i stop. I enjoy you guys thinking it matters.lol

[Miisen]

I never said this video was a lie, it's just not good content. And you've been lying in alot of videos lately so you can't deny that it's a common trend for you

[johnarkans]

Milsen eats anus

[Miisen]

Insults and misspelling doesn't make me care though

[Haltzu93]

5 stars...

[educate9946]

You could just film this, it would be faster.

[AppleSoldier]

Now you may have a point there, lol.

[RockeyRoad93]

that was gash i gave yo a 1 because i cant give you a 0 it took you 7 hrs to render a 7 second clip ah well you can tell you did it on a mac

[AppleSoldier]

you are a complete dumbass. If you dont understand why this took 7 hours than your a noob. mac or pc this would take as long on anything.

[AppleSoldier]

you pc guys rate one star just because you dont like my mac vs pc videos, lol. Your only allowed to rate one star because I ALLOW YOU TOO. I could easily disable it but ill allow you to think your doing something. you do it cause i let you, no other reason.

[macward66]

they are just jealous because their machine would catch fire if they tried this.

[AppleSoldier]

yea, they all claim, this is bad or thats to long or the marble looks bad or teh specular is wrong yadda yadda yadda. not one has any 3d work to show.

[Skutz0r]

i would do 3d work but i just dont have the patients to learn, btw good vid, lacked abit of splash tho

[xtreem0]

catch fire? take longer yes. Catch fire i doubt. (unless its a laptop on a bed... Mined you a macbook would also do the same on the bed.... lol

[Freezer7Pro]

Seven hours? For that?

Come on now.

[AppleSoldier]

If you had any idea about rendering than you would understand. when you render in HD 1280x720 FLUIDS it takes days to do sims. Mac or pc. This is very common times. this is why pixar animations are such a big deal. there machines render 24hours a day for months at a time

[VegasUndergroundLive]

Yeah, This is true indeed, I wish I had a god damned render farm in my basement, lol.

[jmla113]

hey EMEEK, im a noob at this, why does it take so long?

[AppleSoldier]

because its FLUIDS and i rendered in 1280x720 HD These guy who say it took to long etc have no fucking clue about 3d at all.

[sagethishit]

7 hours? I've seen more complex _realtime_ physics demos from nvidia.

[AppleSoldier]

what does that have to do with anything? When you render HS 1280x720 FLUIDS, it dont matter mac or pc. This is done on a desktop not some killer setup. Ive seen those things too and they have major hardware behind it. this is a damn intel 2.6

[stealmind]

you're seriously a n00b, nVidia uses the best of the best (supercomputers) to impress people that have been doing vfx there whole lives, where as emeek is using a single workstation that any consumer can get there hands on if they have a couple thousand dollars

(1000s vs billion dollar setups)

[AppleSoldier]

I think i should thank you for that comment, This is very true.

[Miisen]

Next you should try to make an animation that looks good!

[AppleSoldier]

Next you should try to do one better.

[Miisen]

That's like going to America got Talent and get voted down by the jury and then tell them to do it better themselves.

Why would they, Emeek? Seriously.

[AppleSoldier]

the judges on american idol HAVE REPUTATIONS AND HAVE PROVEN THEMSELVES. I know they can do it, I DONT KNOW YOU CAN. I can take advice from someone better but not someone just talking. Seriously. This is my first time, you make your first try this good and ill say sorry until then fuck off

[Miisen]

So if they don't like someones singing, for example, they can't vote "no" unless themselves can sing better? That doesn't make any sense emeek and if you belive in that then you are really stupid.

[AppleSoldier]

no they are qualified to say what saounds good over you or me becaue they are pros. You say this dontn look good but you have no experience. Tell me, how is it supposed to look? you either dont get it or dont want to. There is a reason they get pros to judge, wonder why? Just like i dont listen to you when you say bullshit. You dont know shit bout 3d. If i cant dance, do i have the right to make fun of you for not being able to dance?

[Miisen]

Everyone has the right to opinions, it doesn't matter if you're "qualified". And you are right, I can't say that everyone dislikes this video because you get alot of good feedback. But this is a 7 seconds long animation and you can't expect everyone to give a video like that a high rating.

[commodore256]

This isn't America's got talent. This is YOUTUBE and I think this video is over nine thousand better than Fred's videos.

Emeek>Fred

[Miisen]

We were talking about Emeeks philosophy that you can't say anything bad about anybody unless you can do a better performance yourself.

[stealmind]

in some sense your opinion does matter it just doesn't matter very much seeing as how you know very little if anything on the subject

[kazoh0lic]

Yeh but you did the retarded thing and went off talking about "America's Got Talent" and comparing yourself to those judges. That's totally different from "having an opinion". The people on those shows have a "qualified opinion". So don't compare yourself to them.

[AppleSoldier]

the original is longer.

[commodore256]

That took you 7 hours??? How many cores do you use? All 8? If all of your cores are clocked around 3Ghz, That would of taken me 56 hours to render. (maby even more)

I rendered a basic snowman in blender and that took me around 15 minutes to render 8 seconds of video. I guess fluids are a bit more complicated.

[AppleSoldier]

oh yes. I can render gemotry in no time, Its fluids and fire etc thats tuff

[alibabaG420]

dude that looks amazin...

[pkerry12]

dam not the first post

o well :)

[aristicolombia]

it looks sick

[AppleSoldier]

FUCK MAYA!

[da1bu89]

Ignorant statement.

[VegasUndergroundLive]

Agreed.

[AppleSoldier]

i mean no offense. I know you like maya, but i dont. And not because of its ability. Its as powerful as houdini i just hate autodesk.

[VegasUndergroundLive]

That answers that the, lol. I was going to ask that in a future video regarding Maya Vs. Houdini.

[AppleSoldier]

houdini can do some thigns Maya cant. Like let particles inherit shaders and the procedural aspect makes it a little more powerful in that regard. Maya is like AE, Houdini is Like shake. Houdini is Node based and Maya is layer based. I HATE THE HISTORY. With Houdini I just go back to the node i need to adjust, no history at all.

[da1bu89]

Maya is Node based - Maya's architecture is based on a Dependancy Graph that shows nodes input and output connections. You can also view nodes using the DAG (Directed Acyclic Graph) and of course the hypershade. I'll try and make a video demonstrating this later.

[da1bu89]

So if Autodesk acquired sideFX like they did with Alias in 2006, you would automatically hate Houdini?

[AppleSoldier]

That my firend would be a sad day. Autodesk just Bought XSI. Now they own XSI and Maya. RThey are becoming monopolistic. The only apps they dont control are houdini, lightwave, and Modo. maybe a couple others. They throe updates into there products nce a year and call it a new versin. They only worry about money. They cant even do a decnt mac versin. Autodesk will kill XSI for maya

[da1bu89]

I think Softimage were looking for a buyer as Avid wanted to sell? But sure i can understand why people are dissapointed it was Autodesk who brought, but XSI have a lot of things going for it - ICE looks awsome.

[nemirc]

yeah, avid put softimage for sale and autodesk bought it. Right now I can't think of any other company that would have made a good buyer...

... unless you count apple, that would mean killing the win version, releasing a mac version for 500 bucks and then killing it 3 years after and implementing the 3d technology in imovie...

[nemirc]

totally
