Basic Comping of a Vray render

[visualride]

Thanks digtlpete! They really do look identical. Would it be possible to post your Combustions file to remove any possible ambiguities and put my Render Elements anxiety finally to rest?

Ya digtlpete, if you could upload your Combustion file that would be much appreciated! I too am having compositing problems that i have yet to solve.

i third that ! Would be very helpful !

Here it is: http://www.brianpeterson3d.com/combu...r_elements.rar

Included in the .rar is the max file, the combustion file, and the rendered footage elements. The only thing that is missing from this example is the use of refraction. Use the same technique as you would with reflections. I believe I also included a max 8.0 1.47 version as well. Please let me know if you have any questions. I am currently working on a tutorial that will cover everything.

I hope this helps to solve your problems with render elements.

thanx!
i ll have a look at this tonite!
i ve been wanting to get this comp thing rite, and it has been a hell of a fight!

I am currently working on a tutorial that will cover everything.

this is even gr8 news!
thanx again!

Awsome! It's great to get such good feedback here.
Good luck on the tutorial, and thanks again!

Thanks so much, that is awesome digtlpete! Looking forward to your tutorial! Will look at your files to see what is going wrong in my workflow; thanks again!

Maybe later I will do some other tips... tweaking shadows, using mattes, doing reflection in comp with the bend normal pass... hmmm... maybe another DVD. Wink

Id pay good money to see that. The compositing shown in this thread is v cool, but its kind of only half the story. These other points you mention would finish the job nicely!

I still having great trouble getting a sound workflow for rendering animations!

i'm having a problem that i cant render out all the render elements to rpf's with out running out of ram. as we render alot at 4960x4960. Does anyone know a way in which I can get all elements as rpfs for combustion work easier ?

I know you can use vrimg file, which writes straight to disk instead of ram, but then i'd have a load of exr's and i like how the rpf's have the extra channel data. Is there anyway to do this ?

ps, hows that tutorial coming along ?

EXR is also multi layered... the the vrimg2exr utility adds all the layers in the exr.

Rhys,

There are several methods for reducing memory consumption, you should do a search. One thing you may try if you are running out of memory is turn off "render to memory frame buffer" in the VRay Frame buffer roll out. Haven't had alot of spare time lately to devote to the combustion tutorial, hopefully I will have something soon.

One other thing is that Combustion is painfully slow when dealing with high res images, just a little warning.

I'm also really looking forward to your tutorial, I hope you can find some time soon to help out all us newbs.

Turning off all the frame buffers helps.

Has anyone actually succeded comping in Combustion yet, doesn't seem to be? I've tried .exr's but just get the blown out effect when adding the two rawshadow and rawgi together like others have said. Also tried .rpf but got the same results which is annoying plus .rpf doesnt seem to like my refraction channel at all. I've played around with gamma for days in each app and had very little success.

PRETTY PLEASE MAKE THIS TUTORIAL.
