There are 11 blend modes that decals can use:

  • Translucent - Can use Diffuse, Metallic, Specular, Roughness, Emissive, Opacity, and Normal.

  • Stain - Is a modulate type blend with Diffuse and Opacity.

  • Normal - Uses the Opacity and Normal channels and only affects the Normal map layer it is projecting on.

  • Emissive - Uses Emissive and Opacity only.

  • Volumetric Distance Function - Use the output of signed distance in Opacity depending on Light Vector.

The DBuffer decals can be used with lighting. These are not on by default and must be enabled in the Project Settings > Rendering section.
