Hi,
I want to MASK BY ALPHA onto one face of a cube but it keeps wrapping around the entire cube. I need to use MASK BY ALPHA because I will have several overlapping masks that need to map to the same points. And the cube proportions are specific.
It works in my friend’s ZBrush no trouble but we can’t figure out what’s happening with mine. Any help will be greatly appreciated!
Mask By Alpha uses the UVs of the mesh to apply the alpha image. So if you want to mask only one face of the cube you need to make sure the alpha is created to match the UVs.
The image shows a cube with one face masked. The flattened cube shows the UVs. You can see that the one face only occupies a small part of the whole image - as can also be seen in the thumbnail of the alpha.
