I have tired using the clay tool with a stencil to indent the pattern into a voxel cube and had it fail.
If I paint onto the cube surface 3D Coat behaves as expected, it builds the surface up leaving the pattern in the cube.
If however I hold Ctrl and just click onto the cube surface to indent the pattern the whole pattern is cut through the cube regardless of the depth setting for the brush.
Am I doing something wrong or is this a bug?
