Hi!
OK, figured it out after some time of experimenting.
- Make a regular Deferred Decal material with Translucent blend mode and Default Lit shading model. IMPORTANT! Disable Tangent Space Normal since DBuffer uses world space normals!
You can also use AlphaComposite or Modulate (=Stain) blend modes - Make a regular material, check Use Material Attributes and setup custom response to decal via ApplyDBuffer. You can choose Decal Response (DBuffer) channels via dropdown in material settings.
- Make sure to disable Receives Decals on your mesh so it will use custom response instead of default one.
