Shadow pass with matted objects - Eric-S - 11-19-2013
Hi I'm trying to get a render with matted object but I would like to have a shadow pass in the openExr buffer.
Right now are work around is the render the fumefx with the matted object using opacity black hole in the shader. Then Re-Render a other pass with fumefx and the objects not matted. But I need to render 2 time the fumefx. In a stereo show thats 4 time the render...
anyone knows how to do 1 render and to have fumefx Matted and with a shadow pass?
thanks,
Eric

Hi Eric,
Do you maybe know how it works with Maya Fluids ?
So, you'd need just a separate shadow pass ?
Thank you.

It was the same issue with Maya fluid, as soon as you put an object with a black hole opacity to create a matte with that object, the shadow in the shadow pass doesnt affect that object anymore.
thanks,

Hi Eric,
Then this could be a mental ray inherited issue in regards how it handles volumes.
We will examine this, but no high hopes.
Could you please email me the scene for the reference ?
Thank you.

same here ... super annoying that there is no way to get the shadows and hold outs in one render.
I get something else which bugs me ... in the shadow pass I can see the geo which intersects with the adaptiv grid (e.g. the floor) in a dark grey color.
Is there a way to get rid of this?
Thanks a lot!

Hello,
Does it help if you move the floor a little bit down and away from the FumeFX grid?
I did try to create the scene that shows this issue, but without luck.
