Tip: Using ICE to drive the OpenGL vertex color display

Courtesy of Vladimir Jankijevic, here’s ” a really handy way of showing
arbitrary colors on a polygon mesh in the viewport, without having to create
a vertex property.”

  • Create an ICE tree that sets self.Color in a per-point context.
  • In the Material node property editor, set Vertex Color Display Property
    to Color.
