Chaos Corona for 3ds Max => [Max] I need help! => Topic started by: Nate101 on 2019-03-10, 07:49:40

Hi all,
As the subject implies, I am trying to deconstruct a CoronaLayeredMtl and reassemble it in post-production (using Photoshop):
- The material I'm working with is a carpaint, it consists of a base coat and a clear coat
- The base coat and the clear coat are each layers in a CoronaLayeredMtl I created
- The mask that "mixes" the two layers is a falloff (fresnel)
- I'm using 32-bit uncompressed EXR's for all renders
My question is whether it is possible to render the base coat and clear coat separately and then combine them in post? If so:
- How do I output the fresnel falloff in 3ds Max to an exr that can be used as a mask between the layers in Photoshop
- What would be the proper "blending mode" to use in Photoshop? Normal, linear dodge or something else?
Appreciate the help.

I tried to render separately base, coat and falloff mask and combine in photoshop. It almost works... except for self reflection. I have no idea if it's possible to overcome this issue.

Thanks Romullus. The self reflection was an issue I noticed as well. How did you output the falloff mask?
-
Through CTexmap render pass.

Ah yes, I guess that should have been obvious, I was making it more complicated than I needed to.
Would love to know if devs have any insight, would really be a game changer for me if I could render these out separately.
