# SetMeshMemblockVertexColor

## Description

Provides a quick way to modify the color values of a vertex inside a mesh memblock. It uses the attribute data from the beginning of the memblock to work out the vertex offset and change the color values. Vertices start at index 0. Color values must be between 0 and 255.
