UnityDeferredDecals

Improved version of unity's deferred decals system with support of layers and some basic frustum culling.

How to use:

  1. Essential files are stored in Assets/DeferredDecals. You can copy paste this folder to your project and everything should work fine
  2. Add DeferredDecalRenderer.cs to your scene. There should be only one renderer
  3. Use GameObject/Effects/Deferred Decal to create decal
  4. Use GDecalShader shader for your decal material
  5. You're amazing :D

Pros:

  • Improved inspector with embedded material editing:
  • Layers. Though making layers is pretty expensive since the more layers you have on screen the more passes are needed.

  • Cutout. Each decal can use Alpha Clip to avoid using layers
  • Blending with background normals
  • Decals can influence smoothness and specular color, using Metallic workflow
  • They are still rendered if you're inside the render box

Cons:

  • No special normals/diffuse only decals, so each decal layer does copy 3 GBuffers no matter what
  • Visibility in editor can be clunky
  • Shader is under development. No emission support yet
  • No instancing
  • Culling doesn't care about walls, it's just AABB check. For now
