Blender 2.56 SPH Fluid Tutorial

[Eskapn223]

Ps don't ever Change Fludi to any else when you have press'd play

[Eskapn223]

Step 6:17 when i press play the Fluid is flying everywhere

[Animation8000]

When I change it to "Fluid" the particles just explode into random directions on the screen, not being affected by gravity and out of control. NO settings were changed... ??????

[SpiritCrisis]

@Animation8000 as long as you follow the extra directions in the description everything in the video works fine... I used all of these settings all last week to work on a new tutorial.

[adriou5]

Wow man, slow down !

I don't even know how did you scale it at the begening, it dosen't even work.

[SpiritCrisis]

@adriou5 if I were to slow down any more the video would have been 30 to 40 minutes. The settings work I used them all of last week to work on a point density project

[SmudgeFiststudios]

great tutorial , great walkthrough manner i spoe you'd call it. like bedside but for the viewers of your video :)

[masterapmark]

@SpiritCrisis Sorry for the extra trouble, I didn't start Blender too long ago... Where and what is Integration?

[masterapmark]

Where are the

Verlet

Time Step: 0.04

Subframes: 1

???

[SpiritCrisis]

@masterapmark its still there. under Integration theres a pull down menu for you to choose Verlet. Time Step is underneath it and subframes as well. Make sure you have Fluid Selected under Physics sections of the Particles tab if you do not see these option. I am using Blender 2.61 to check these settings for you if you are curious

[NikeTao]

How do I get more fluid? - I mean is there a way to control the amount? It only gives me very little.

[godisman1234567890]

THX I´ll sub and Like because of this!

[sciguy1121]

Hm..., my stiffness parameter doesn't do anything. What am I doing wrong?

[zyon4791]

Great tutorial, thank you.

[jonnymurder]

"and there's poo... delicious poo"

I got fired from my job today. That quote made my day!

[SpiritCrisis]

@jonnymurder glad to have cheered you up. Sorry about the job and good luck on finding a better one

[blaketheawesomedude]

So no matter what I do my particles refuse to "blob" together they just stay individual particles.

[blazraidr]

i have a test with 100000 particles!

[AnimationGuy155]

when i change from newtonia to fluid my particles fly in every different derection. please help

[SpiritCrisis]

@AnimationGuy155 please follow the directions in the description

[AnimationGuy155]

@SpiritCrisis thanks

[Tyirel]

@SpiritCrisis i did what the description said... however my particles are still all over the place... just less all over the place, like instead of shooting bullets its throwing rocks in every direction...

[tiggerbiggo]

Help! I don't have the "fluids" physics setting in my particles! heeeelp!

[SpiritCrisis]

@tiggerbiggo What version of blender are you using?

[theFLProd]

ok first of all i have the newest version of blender and there is no radius thing and when i use stiffness it doesnt change anything so PLEASE HELP/REPLY

[SpiritCrisis]

@theFLProd ill have to try this on the latest version of blender. Im not sure how much time im going to have this week to do anything so please send me a Private Message so I can keep it in my log to look over when I get some time. Hope I can figure something out for you :D

[BBrtqB]

Thank you so much for all these videos, they really help. :D

[tominator923]

You are awesome! Thank you! Also, what are your graphics card's specs?

[chocolatewaffels]

what kind of computer do you have?

[putthisonmytab]

When I change it from newtonian to fluid in the physics, my particles don't continue to flow they start to go all over the place in all directions. Why is this, and how can I fix it? Thanks.

[SpiritCrisis]

@putthisonmytab there are multiple reasons for this. If you didnt start back at frame one and press play to update the animation, you have to many particles, your settings are bad, or you may just need to save and restart and reload blender... If you forgot to set one setting proper then it will explode everywhere mostly if you set something to high..

[putthisonmytab]

@SpiritCrisis Thanks man i'll give it another try :)

[nugentboy]

@SpiritCrisis same here, i followed all your settings so far and restarted blender but the problem is still there :/

[SpiritCrisis]

@nugentboy ill have to retry these settings on the current blender version. ill get back to you... if not pls DM me

[nugentboy]

@SpiritCrisis ok, thanks :)

[cepomwa]

@SpiritCrisis same here, when are you going to give us a solution?

[thalion77771]

@putthisonmytab hey, i found out that its because of the interaction of the particles in the physics options. i guess the newer versions (i have 2.58) set it to 1.i like it at .290 but its up to you

[putthisonmytab]

@thalion77771 Thanks for the reply man... or woman XD I'll definetly give it a try.

[Ramiprops]

I have a problem; When I bake any fluid ontop of a diagonal surface, it seems like it was flowing down a stair. How can I solve it?

[SpiritCrisis]

@Ramiprops try a higher rez fluid that should fix the issue if you are still having issues please message me and ill look into it :D

[videofountain]

Thanks. Helpful Video.

Sometimes in the video you have expressed a little uncertainty.

You stated ... 05:56

"tell you what each option does in my opinion".

Is that because you cannot find documentation?

I am looking for documentation

[SpiritCrisis]

@videofountain good point this is why I didn't want to make this video. When I made this video there was no hard data or data at all on what does what. So when I researched this I just tried to come up with my best understanding and put a video out there. The only reason I made this video is because allot of people have been requesting this topic and no one has a good tutorial on it.

Hope this answers your question.. Have a great day....

[videofountain]

@SpiritCrisis

I believe its quite fair and useful to say this topic has little official documentation.

IMHO this taboo topic of documentation for Blender (B) really hurts the product.

The lack documentation for the Beta (B) convinces some people not to want to use (B) at all.

Some would rather pay cash for a product that DOES have documentation.

Even Beta Software can serve its customers by having base doc on the day of release.

Blender mgmt chooses minimal documentation training to users.

[videofountain]

@videofountain

Addendum

If Blender.org provide satisfactory and reviewed technical documentation ... then you and others could translate this into user documentation ... with creative 3d compositions

[videofountain]

I did have a problem.

I wanted the particles entering then remaining in a particular container.

I had some luck but in some occasions the particles wiggle out.

I want the middle to end frames to show contained particle volume to be constant ..while individual particles can wiggle around.

I want them to enter container and stay in container. Only exit container at my choosing. I am having trouble identifying the correct parameters to set or animate.

Any ideas?

[Officially2015]

Also, I'm on 2.57 and some things like 'Radius' under FLUID are gone.

[SpiritCrisis]

@Officially2015 ill be looking into this when i get some free time... there's going to be a part 2 of this video anyways lol... Thanks for the comment and ill try my best to answer these questions in the next part of this series.

[Officially2015]

Whenever I switch it over to FLUID, under particles, they start exploding all over the place instead of regularly falling. I can't figure out why.

[richmeister4eva]

is this better or worse than the actual fluid sim in blender

[SpiritCrisis]

@richmeister4eva to me its worse but I still have to spend allot more time on it and see how things go. Just a matter of investing allot of time and effort into learning the perfect settings for what you want

[qpdksf5]

FYI, if the sphere is that small, you can reduce the height and width after you add it, this makes it a lot faster. :) Great tutorial. Also, how do you upload videos longer than 15 minutes?

[SpiritCrisis]

@qpdksf5 i have been approved by youtube to do so.

[mobilefreek]

Nice to able to see a textured variant on the end result. Make it a two part tutorial ?

Inspirational!

[SpiritCrisis]

@mobilefreek there is another tutorial coming down the road with some composting aspects to these sim's just tell me specifically what you would like to be done and ill try to work on it... by what do you mean textured... particles or duplivert
