Unity Rendering Pipelines to Simplygon

Simplygon supports material casting of Unity material models Standard, URP (URP/Lit shader), and HDRP (HDRP/Lit shader) via ComputeCasters easily accessible in the Simplygon UI in Unity.

Standard to Simplygon channel mapping

Below is the mapping table between Unity (Standard) and Simplygon.

SRGB Channel support

The following list specifies all the supported channels in Unity and if simplygon handles srgb on those channels.

We also list if Unity supports srgb on these channels for easy of reference.
