Unshared vertex colors

[aspong]

Hi,

I am trying to find an easy way to determine if a vertex has unshared vertex color information i.e. that unique vertex colors have been applied to vertexFaces, such as you would use to get a hard edge to vertex colors. If you look in the component editor, it will report that the colors are unshared, but I do not know how to get that information via mel. Otherwise, it gets very messy with looking at the vertex color information for every vertexFace and then comparing rgb values to see if they are the same or not.

cheers,

Al

I thought this was going to be an easy one, but now that I look more closely, I have been surprised.

I would have thought that selecting a vert with more than one color and using the command

polyColorPerVertex -q -rgb

would return multiple sets of RGBs if it was unshared. That is not the case, however. This sort of thing must only be available through the API.

Exactly, in fact, that command appears to give you an average of the colors. It's a crucial optimization to find out if a vertex is shared or not because it is very time consuming to iterate through every vertexface.
