glTFast 4.5.0

This release tackles a couple of material issues in URP/HDRP and simplifies future material extension work.

Upgrade to 4.5.0

New shader graphs are used with certain Universal and High Definition render pipeline versions, so projects that included glTFast's shaders have to check and update their included shaders or shader variant collections (see Materials and Shader Variants for details)).

Changes

Added

• Generic shader graphs (to reduce the amount of shader graphs to maintain and reduce shader variants)
  • glTF-pbrMetallicRoughness
  • glTF-pbrSpecularGlossiness
  • glTF-unlit

Changed

• The new, generic shader graphs are used for
  • Universal render pipe 12 or newer
  • High-Definition render pipe 10 or newer
  • Optional/Experimental for the Built-In render pipe (see Shader Graphs and the Built-In Render Pipeline in the documentatoin for details)

Fixed

• Correct emission in HDRP 12 and later
• (Shader Graph) Vertex color alpha channel is used properly
• (Shader Graph) Correct vertex colors when project uses linear color space
• (Shader Graph) Emission is now in correct color space
