Hi,

There is something that I do not understand involving the color of objects and the boolean union operation.

In the first simple image the pile of objects of different sizes keep their colors after a union, not so the pile of same size objects. The image is pre-union.

The second image shows what prompted my question. The model is composed of different "layers" of objects to allow applying different colors. But after the union the colors are messed up.

What is the "correct" way to have multiple colors on such a model?

Thanks much.

Frederick
