Title: CoronaPhysicalMtl - Vegetation Shader
Post by: cjwidd on 2021-09-29, 08:25:53

There is no clear method for converting a complex [vegetation] shader using the CoronaLegacyMtl to the CoronaPhysicalMtl, and the reason for this is likely due to how:

1. Refraction glossiness is yoked to base glossiness
2. Translucency, thin shell, and thin absorption are decoupled

Should I upload a sample to troubleshoot this, or just rely on the Legacy material for now - until (hopefully) there is an official converter solution for cases like this(?)

Please do share the sample with us, relying on legacy is also an option as well.
