Diffuse or Base Color Channel

• Diffuse or Base Color channels for Texture, Ribbon and Mesh Emitters

  The textures in the Diffuse or Base Color channel give the particles a basic appearance or skin look.
  

• Diffuse channels for Distortion Emitter
  
  • The Diffuse channel of Distortion in the Resource List is actually for loading Normal texture.
  • The Diffuse channel of Tint in the Resource list is for appending blending colors to the distortion effect.
    

Normal Channel

The Normal channel can be used to create the bumpiness on the surface of the particles, either for billboard-based or mesh-based particles.

Metallic and Roughness Channels

The Metallic and Roughness Channels can be used to present PBR effect for each particle. The particles can then reflect the environment.
