Hello guys,
I know these have been asked about previously but with no solid plans announced I would like to ask what are you plans for properly supporting Bump and Opacity in Vray material. Currently, they are very limited and force users to neglect them in their renders or try hacky workarounds which don't always get you what you want or is impossible to replicate another way.
Recap of their limitations and some use cases which current implementation causes issues. I understand the desire for optimization, mainly in opacity but I believe we should get the choice as a bare minimum so we can actually deliver the work we need without workarounds or simply not being able to include it in the final output.
Bump
Limited to purely bitmap textures
Does not support any type of procedural maps which are very common in assets created for Vray along with compositing different procedural textures which again is very common using mix, composite maps etc.
Currently does not support UVWRandomizer fully
Opacity
Only supports black and white values.
Limited to purely bitmap textures
Cannot create fog cards or cloud cards. Need to use refraction hack workaround which has its own issues.
Does not support any other type of map in the slot which would be used for creating effects such as holograms. Holograms cannot be created using the refraction workaround. You need to use the falloff map which when used in a refraction slot, black == no refraction (solid) whereas black in opacity means completely transparent.
Thanks
