Quick, simple zbrush question re: backface culling masks.

mikejkelley · Jan 2016

How do I limit Rect masking to one side of a cube? Ie, make sure the backface isn't masked as well? To be clear, I'm not asking about how to limit sculpting to one side of a mesh (ie Brush>Auto Masking>BackFaceMask). I'm trying to mask the windows on the North side of a house and the South side gets masked as well.

I'm not sure if there's a setting but probably the easiest way to do this would be to just hide the back before masking the front.

Or just mask all the windows and unmask the back. There is no setting to avoid this.

Since they're windows, you should be able to automatically create polygroups based on the surface normals. This way you can at least isolate the sides you want to work with and mask the rest.
