VRay physical Camera Problem
show user profile  HG
I rendered a scene with 3dsmax 2016 and VRay 3.4
I used the physical camera. now I want to render the same scene with scanline Render to have alpha channel and ZDepth. But when I render it and bring it to aftereffect I see that the two file doesn't match with each other... No mater what I tried it didn't get match ... any Idea ?

>> "doesn't match with each other"

you're going to have to be a bit more specific than that. Focal length doesn't match? Colors don't match? Anti-aliasing doesn't match?

the physical camera has (can have) distortion and focus breathing, so a scanline probably won't ever match 100%

Any particular reason you want the alpha and ZDepth from scanline instead of V-Ray? -

In C4D we have an option for the Vray Camera to use 'pin-hole' mode. This matches resident and vray cameras exactly.

I think it is something in focal length. but I'm not sure. but as I bring my files into aftereffects they doesn't match.
I rendered my original file in exr extension.
the funny thing was that if I render it in VRay but not exr extension . for example jpg. it will not match once again. so for having a ZDepth path I was forced to stay in VRay and render my Alpha Channel and ZDepth once again with VRay.

hm... the file type shouldn't change anything, except maybe the color space.

can you post images of the difference? Still not sure why you can't use the zdepth and alpha from vray, or why you need to render them separate. Are you using the embeded channels? -
