ZDepth and others Renderelements with AerialPerspective/EnvFog

[JonasNöll]

Hi,

the problem also exists in earlier V-Ray versions but basically when you enable EnvironmentFog or AerialPerspecrtive your zDepth Renderelement will be screwed up. Would it be possible to remove the Fog from the zDepth evaluation as it gives strange results?
Similar problems also accuring in the AlphaChannel, and worldNormals and possibly other passes as well.





Maybe could have an option in the Fog to not affect RenderElements or something like this?

The idea is to have some options for these somewhere along V-Ray 6.

Here you can check a build with an option for the Alpha channel - https://nightlies.chaos.com/main#/vr.../beta/20220610

There are some other improvements in those builds as well, but I'll list them in some other thread.

edit: forgot to mention that this is a very initial state of the work that is going to be done on this topic
