Deferred Decal material

Development Asset Creation

Hello,

We have experienced an issue when setting up material for deferred decals:

Material domain: Deferred Decal

Blend mode: TranslucentGrayTransmittance

There is a difference in visual output when setting attributes Metalic, Specular and Roughness directly into material node compared to setting the values through constant nodes. Values set directly in material node are not evaluated correctly.

Steps to Reproduce
See attached images for details.

  • Create 2 materials, domain=DeferredDecal, blend mode=TranslucentGrayTransmittance
  • Set metallic, specular and roughness (0, 1, 0) in one material directly in material node
  • Set same metallic, specular and roughness values in second material but connect the via constant nodes
  • Observe differences in visual output
