Blender Tutorial - Simple caustics with YafRAY (0.0.9)

[True2TheBlueYoViGang]

i like he started the intro with a pedo voice "ugh yeah... HI.. this is DAVE!" lol Hey dave how did you get windows to have a sort of Ubuntuish gui window layout? i thought it was Ubuntu-linux until I saw the task manager...

[agent47crows]

@True2TheBlueYoViGang

Hi, this is Dave.

Yeah, in order to get that look, I used some skin thingie for XP. I don't recall the name of the program I used, but I know the skin was called Luna.

[True2TheBlueYoViGang]

@agent47crows

lol cool i thuaght it was vista i guess its pointless asking for me cuz i have 7. cool skin tho. thanks for the reply. xD

[razorskateful]

what the version is your blender?



[agent47crows]

@razorskateful

2.45

[MrsBlindStudios]

At about 2:20 You talk about the two tabs next to the render tabs- Yafray and Yafray GI, I don't have those ones but I do have Yafray.

[agent47crows]

@MrsBlindStudios

Sorry, dude, must be some API change. I've done this for a very experimental (and old) version of YafRAY.

Even if we used the same version, there are bugs to be encountered yet.

[dudeinasuit]

lol..

yeah hi

[hellstudios]

@dudeinasuit Indeed. reminded me of office space.

[joshua987430roblox]

i'm trying to make a animation with yafaray but when I render it makes each frame a different picture it doesnt make a video

[pyrogirl64]

@joshua987430roblox: You have to choose the right file format. If you go to the the "format" tab in the render buttons, you'll notice a drop down list. This is where you choose the file format for your final render. If you have it as eg JPG, GIF, PNG... then you'll just get a series of pictures but if you have it as for example, AVI raw, then you'll get a video clip instead.

[MrsBlindStudios]

@joshua987430roblox I've got the same problem... did you figure it out?

[agent47crows]

@MrsBlindStudios & @joshua987430roblox

That's just the way it's supposed to render.

You take the individual files (by default they should be PNGs) and merge them in a sequence editor. You can even use Blender's internal sequence editor, then render the sequence as AVI or whatever video format you'd like.

[MrsBlindStudios]

@agent47crows Do you have to add each image separately and then scale them all down to fit one frame or is there a quicker way?

[agent47crows]

@MrsBlindStudios

Well, no, if you get 2 or more images in the sequence editor, it'll automatically detect them as a sequence of frames, thus each image corresponds (by default) to one animation frame.

So, select all your frames when importing them into the sequence editor.

For 2.49 or lower, right click on the last file, then drag the cursor a tad down (it'll select them all).

For 2.55 beta, click&drag (for a selection), then shift and repeat the click&drag (I hope there's a select all thing)

[MrsBlindStudios]

@agent47crows Thanks, that worked. :)

[agent47crows]

@MrsBlindStudios

Anytime!

[MrsBlindStudios]

Also, you do get caustics with a magnifying glass.

[XAutomatedOwnerX]

I dont have that little combo box under the render button where it wtiches to yafaray

[XAutomatedOwnerX]

Nvm i found out i have the later version

[richmeister4eva]

could you help me on the new yafray import its totaly different to me

[xXMadTXx]

Yeah, I don't see the caustics thing.

[iuliusCamillus]

Are there any alternatives to Yafray that are free to download?

[ctgartland]

LuxRender is another free renderer, although it is extremely different compared to YafaRay.

[iuliusCamillus]

Thanx for the info! I'll try it today.

[aggitann]

Try looking into; POV, SunFlow, & Kerkythea

[aggitann]

POV-Ray

[iuliusCamillus]

I still can't get Yafaray to work. I'm using Blender 2.49 so which version of Python do I use to make it work. I can't get a satisfactory answer on the Blenders site.

[ctgartland]

You need to get Python 2.6.2. I think the current version of Python is 2.6.4, but you should download 2.6.2 just to make sure it works with Blender. A simple search should bring you to the page for the 2.6.2 release. If you simply go to Python's website and do Downloads>Releases, only 2.6.4 will show up, so search "Python 2.6.2" and the correct page should be the first result.

[Dark0Lord7]

@iuliusCamillus Click Render> Yafaray Export 0.1.1

[cubesrock]

@iuliusCamillus

2.6.x

[EMAN360ELITE]

At frame 0:59, the "Choose rendering engine" drop-down list does not show up in the Blender 2.49b that I am running.

I have Python 2.6.2 and Yafaray 0.1.1 installed. I can export to Yafaray and everything renders fine, but I cannot toggle the Rendering Engine from "Blender internal" to "Yafaray 0.1.1" This would make a WORLD of difference to the functionality of the program for me.

Any suggestions?

[JulyForToday]

2.49b doesn't have that drop down. You can access yafaray (or any other external renderer) through the Render menu at the top of the GUI (next to the help menu) or through the scripts window. The settings will open in a window like any other python script, rather than panels on the button menu.

Check the official Yafaray instructions on their website, they should work perfectly.

[shefshofabsehr]

When i render, its just a black frame?

[rschiwal]

Yafaray has it's own lighting settings. Click on the light with the Python menu up and set to objects and your lighting settings will appear,

[enixo96]

you have ice xp?

[Zedazih]

Could you please make an update of this video for blender 2.49. Because the yafray settings are so weird. And I can't make caustic because of yafray won't render my material settings. :)

[agent47crows]

Since the new version of YafRAY ( YafaRAY ), they changed a lot of stuff (some I can't even understand myself). Basically, you don't do the options from Blender itself, you load the export plugin (the py file) and it pops up a console in the script editor. Then you select the options and stuff. Hope it helps.

[mov0001000]

You should have shown the final rendered animation at the end.

[Nkatsikanis]

how different are the colours in YafaRAY to the default renderer

[Lee6720s]

ya know, I COULD HAVE YOU AS MY ICT TEACHER !! your so funy, and casual while talking which I think Makes Your Tutorials That much more Fun To watch.

[agent47crows]

Hehe, thanks.

[trigg3r14]

i have a problem with yafray, common problem but everytime i try and find a solution eklsewhere i get patronised and told to reinstall ,,, yeh because i didnt try that before i asked,,,,,,anyways

do you have any ideas as to why yafray just renders a black screen? .... i have python 2.5.2 and everything is working fine, i can export to yafray and all that. just as soon as i press render,,,nothing =[

[agent47crows]

Yeah... That's because you have YafaRAY (probably). You need the python version you have + YafaRAY + some python to integrate it. The installers are very messed up, so locate all the files it installs and put them in your .scripts folder.

Then, instead of rendering, click on the Render menu, YafaRAY exporter and that's pretty much it.

Hope it helps.

[BlenderPenguin]

dude you always have the best wallpapers out of all blender teachers!

[agent47crows]

lol thanks.

[kellee101]

Yup...Blender crashes when I disable XML. Why? I dont know. Maybe my computer is crap.

[mov0001000]

I got the same problem. It is a bug with 64-bit Blender 2.48 (is it fixed it 2.49?).

[zacariasc]

(ie-coe-sphere)

[Freak6758]

when i render in yafray, the render window stays black and it says there is a python script error (i have python installed) and i should check the console. I don't know how to use blender with python. what do i have to do with python?

[mawc14]

same

[RagstoRich]

same thing happened with me. right wot u've gotto do is this...

u've probably noticed that when you start Blender there's a box that comes up with it with writing in it that says something like:

searching for python... no python found

continuing happily...

if so then u've got the wrong python installed. look at the top of that box it should say :

compied with python version 2.5.2 (or maybe another number)

u gotto download and install that version on python for blender to recognise it.good luck

[cyberlord64]

i know that i am drifting a little off the subject but i just gotta ask...

How the hell did you manage to do that dual core thing? i have searched everywere and found nothing! could you at least point me to the right direction?

[agent47crows]

In all fairness, dude, I have NO idea what I did. I don't even know if I did it, but I remember changing the BIOS version like a lunatic (NOT RECOMMENDED, IT COULD SCREW YOUR MOBO FOREVER).

[glarusman]

It is called Hyper-threading. Some intel processors support it. search wikipedia for the article and list of processors. It is simultaneous multithreading.

Keep on blending.

[RadditzZ]

hm doesnt work

i've installes python and c++ (of the links on the yafray site)

[Blinkwing]

when i render in yafray, the render window stays black, did i do anything wrong?

do i need python?

[estebanblack]

yes you do also you need other stuff to install yafray

[Blinkwing]

yeah, i know, tfinally worked!

[loopedrope]

wow its like u made this tut to impress people

[agent47crows]

Hell, no! =)

[Blinkwing]

lol, yafray has got lots of advantages, but can u tell me which?

[agent47crows]

I have no idea, dude, I don't really use YafRAY much. From my experience, the advantages are: caustics and Global Illumination (GI).

The render time... not so much!

[Blinkwing]

ok, i try with python installed xD

[ScaroDj]

If the answer is steel useful:

Use yafray when you need real light interaction. For example, if you place a red ball besides a white cup and you need the red light reflected from the ball to affect the white color of the cup.

[Blinkwing]

yeah, these are the limits of the blender rendering engine!

[AlekeanderK]

Well, Halo like image can be considered a parody, so it is not stealing.

And it is not really a logo or a trademarked idea. SO USE IT ALL YOU LIKE.

Besides music an other companies try to make you think you have less rights then you actually have.

[mrbublik]

i have problem when i do render

when i click render

mt bledner colse :|

[agent47crows]

Hell if I know, dude.

Mess with the settings (disabling XML is known to cause some errors, so try leaving XML enabled)

[UNiqEz]

lol man hahaha wtf...

you said we can toy with your settings!!!

hahahaha

dang!

JK

yo i have a question...

i use yafray.well i don't because

it crashes my pc some times

and it looks nasty too(not all time). any thoughts!?!?

[agent47crows]

Well, if you want it NOT to crash, just toy with the settings a bit more, with a simple scene (a cube and 1 light). I think your problem might be the XML function (it varies from PC to PC to Mac). Again, you have free will, free time, you can always choose what's best to you.

But all in all, de-activate the Ambient Occlusion... much quicker without it.

[Axisistilter345]

hey, just thought i would ask, whats the difference between global illumination and radiosity?

[agent47crows]

Bingo-like question dude!

Frankly, I dunno, but I am 65% sure that with global illumination you can get data from HDR maps better and faster than with full radiosity, whereas you get more quality with radiosity if you select radiosity only.

[BlizzardT1]

nice tut ty.

[agent47crows]

Hey, no problem!

[ScottIsHereRightNow]

abrupt ending lol

your tutorials are fun to watch.

[agent47crows]

Aye, yeah! Thanks.

[designerskate]

i'm not sure if someone has told u this yet anyways... water ior is 1.5 hope it helps if no one told u :)

[agent47crows]

Dang! Thanks dude, I got it all confused, then.

Much appreciated! (so, water it ~ 1.5, ice is 1.56 to me... what the hell was 1.26, then??)

[agent47crows]

You probably forgot to add a normal lamp. By altering the settings of the default lamp in YafRAY, you set it to photon, so that means it will emmit photons only in the meaning that it will shoot different rays that won't be used in the special illumination shader style.

Try adding a normal lamp as well and it should turn out fine.

[LiquidFl4me]

oh and did you have an old account called xefpatterson

you people sound the same and both have somthing to do with animation and i herd you guys played the guitar so are you the same people? just wondering and also thanks for all these great tut's

[agent47crows]

Nah, good ol' "agent47crows" is the first account and probably the last on YT.

And I play electric guitar, yeah.

Thanks for the comments.

[LiquidFl4me]

wow man your the best ever!!!!1

[agent47crows]

Thanks dude, but I am by far just an apprentice.

[anpuZA]

how the hell do u get it to render so fast? what machine are you using?

[agent47crows]

It's not exactly the machine, it's kinda a very old CPU (Pentium IV 630 on ~ 3.014 MHz, not even dual-core).

But I usually hack everything and tweak everything, so I got mine to look like dual-core for the system and I reduced all the non-vital details to zero.

And I format about every 6 months and I NEVER OVERCLOCK!

*basically, I just get 200% of my PC doing my magic stuff

[Skomakarn]

It's pronounced isosphere, even though the spelling is strange. In Swedish, it's spelled with an s (I think xD).

[agent47crows]

That's it. I am modifying the Blender source-code to make it be called "the sphere which is not so much of a sphere". It's a little bit nicer, aye?

[mykatanaiskool]

great tut.

ive beed woondering how to do that. lol. ;D

[agent47crows]

Yeah, so did I. Notice you have to set an IOR greater than 1.00 if you want to to mirror caustics (dunno why, though, but it affects the caustics on mirros).

[gyrfalcon23]

dude omg you pronounced yafray wrong!

everyone knows its yay-fray

god!

oh btw are you still planning on rendering my water thingy? plzzzzzzzzzzzzzzzzz

[agent47crows]

I pronounce it Yeah-fray... with a hint of "leave me alone". It actually can be a motto on most of the PCs due to the long time you have to wait for a render. Then, the PC says "Leave me alone, kid... it ain't gonna be over till next year!"

Anyway, your water thing is malfunctioning. I need the other files, dude!

[gyrfalcon23]

dude what files

"leave me alone lol"

[agent47crows]

The tar files, with the whole damn water simulation. HELLO, dude, I asked you what res you wanted, ye never replied. You already know you can't have a simulation without the key files.

[gyrfalcon23]

oh noes

so thats why the packed file was so small

srry about that..

umm if you dont mind umm like 150 plz??0.o

[agent47crows]

OK... you do know you have to send it again 'cause I can't find it anywhere. Not even in Recycle Bin.

[gyrfalcon23]

that sucks

all the associated files are gone from my comp...

umm if i can ill send it

[blenderass111]

copywrite infringment!!!!!!!!!!!

[agent47crows]

Yup, I'll get busted.

[blenderass111]

bungie is gonna be on u like white on rice boy and im not postin bail i mean seriosly u had this comin

[agent47crows]

...or worse, Microsoft.

[blenderass111]

oh god if that happens then bill gates is gonna take more money from you even though he already has $25.6 billion because he needs that extra thousand so he can afford the homeowners tax for his casstle in britain

[agent47crows]

Or I'll beat him at Guitar Hero 3 and he'll pay. (pun intended for the new interface show when Slash showed up on behalf of Bill)
