TRanslucency Element thru glass

(1/2) > >>

MESTRE BIGA:
I cant see th object in Translucency Element thru glass if I am using a Physical Material what does not occur when the material applyed is legacy material. Is there a workaround in physical mtl that does work?

Thanks

Aram Avetisyan:
Hi,

So here is what I found:
• Legacy and Physical material, with full refraction, no thin mode - they act the same, meaning objects which contribute to CESSENTIAL_Translucency render element are NOT visible through objects which have mentioned materials applied
• Legacy and Physical material, with full refraction, with Thin mode - they act different, meaning objects which contribute to CESSENTIAL_Translucency render element are visible through LegacyMtl and not through PhysicalMtl.

Is this exactly what you are referring to? The Thin mode option is the key here I think.

MESTRE BIGA:
Exactly!

maru:
Perhaps enabling mask propagation would be the solution here? https://support.chaos.com/hc/en-us/articles/4528327507729

Aram Avetisyan:
Mask propagation does not help here, there is a difference between Physical and Legacy materials on how they treat thin mode glass for Translucency render element, which may be expected for Physical material.

Nevertheless, this is reported now.
