Vertex Color Sample

This material graph sample demonstrates how to use vertex color for texture blending when creating materials.

  • Each of the color channels (RGB) gets its own Linear Interpolation expression.
  • The data from the first albedo Texture (0) sampled by the Sample2D node is plugged to the x port of the first Lerp node.
  • The data from each of the other three albedo Textures (1-3) sampled by the corresponding Sample2D node is plugged to the y port of its corresponding Lerp node.
  • The first Lerp node corresponding to Texture 1 plugs into the x port of the Lerp node corresponding to Texture 2, with Alpha driven by the Red channel from the vertex color (connected via the X port adapter).
  • The second Lerp node corresponding to Texture 2 plugs into the x port of the Lerp node corresponding to Texture 3, with Alpha driven by the Green channel from the vertex color (connected via the Y port adapter).
  • The third Lerp node corresponding to Texture 3 plugs into the Albedo port of Deferred PBR Material master material node, with Alpha driven by the Blue channel from the vertex color (connected via the Z port adapter).
  • Four Normal maps sampled by the corresponding Sample2D nodes have the same kind of setup of Linear Interpolation expressions.

Finally, the data output is passed to the Final Material node.
