Vertex Color OperatorBasic Parameter
Vertex Color Operator
With the introduction of the Vertex Colors, a Vertex Color node is also available, which can be used to read and set color and alpha values per object.
The values for R, G, B and A (alpha) each lie between 0 and 1.
The Vertex Color node works best when Vertex Colors is set to Points Only (Vertex Color tag), for which exactly one color or alpha value will be saved per vertex.
In Polygon Points mode, only 1 average value per vertex can be read out, or 1 value set for all polygons to which the vertex belongs. C++ or Python must be used to access the Polygon Points data structure.
