Rendering RAW & LEVEL separate passes in maya

[shehanRN]

Can anybody pls tell me how i can separately render RAW & LEVEL channels in maya ? In 3ds Max it's already there in the render elements
but how can i do it in maya ?

for EX

if you just want the reflections in a separate channel, use the Output Reflections , but if you want more control over the amount of reflections in post-production, you can instead use Raw Reflections and Level Reflections, multiplying them together and get more control over
ur reflections. Same goes with diffuse, and others.

In 3ds max it's very easy to get these passes , but how can i get the same passes in maya.

very great-full for any help u can give.

Try to use writeToColorBuffer nodes with custom color render pass!
it`s a bit of mess to set it up and might take a while but it should work! :)

thanks Villijs

the writeToColorBuffer nodes Worked .. But it is a real pain to set it up.
But still i could not figure out how to take the rawGI and FG pass .

[Villijs]

Indeed it is! The same as working in maya! :D
AFAIK, GI and FG always go together and is called indirect pass (also with AO multiplied with it), and you`ll need to connect every mia_material_x_passes indirect_result output to seperate writeToColorBuffer node! :)

* in love with maya... that makes two of us

and autodesk!! ¬_¬ rrrright...

just kidding! :P

it is relly a pain to set up, but you can make a simple mel to connect or dissconect all of your materials, i think djx has something in his blog (http://www.djx.com.au/blog/) i just dont remember where

thanks again Villijs & peengoh

I got all my passes out But i ran into a another problem . In my scene i use the MR SUN & SKY and two area lights and hook the MR Portal light for them . And hooked up MR BlackBody to the Portal Light. In the camera lens i put the MR Photographic Exposure.

But when i take my Render passes it's darker than
whet i see in maya ..

Is it because MR Photographic Exposure is not included in my passes. ? is there away to archive this .

thanks again...

I wouldn't bother with any Exposure nodes when using Rendering Passes. They can really screw up the results. I recommend using an HDRI instead of Physical Sun & Sky for that very reason.

You're much better off making the all the gamma corrections yourself in the compositing stage.
