Single-Material Layer with Overlay

This chart shows a single material workflow enhanced by an overlay.

• Single material layer
  The starting point is one main material.

• Base Material
  The primary material surface (e.g., clean metal, plain ground).

• Overlay Layer
  An additional layer applied on top of the base material (e.g., wear, dirt, moss).

• Transition Mask
  Controls where the overlay appears on the base material.

Multi-Material Layer Blending

This chart illustrates a multi-material layering workflow where two independent material layers are combined.

• Multi material layer
  This is the starting point that contains multiple material definitions.

• Layer Top
  Represents the material that visually sits on top (e.g., dirt, snow, paint).

• Layer Bottom
  Represents the underlying material (e.g., rock, metal, ground).

• BlendMaterial (Transition Mask)
  The top and bottom layers are blended together using a transition mask.
  The mask controls where and how strongly the top material appears over the bottom material.
