Thanks for logging that Greg!
philnolan3d, I don't want to change the depth. I want to draw with brush one, and when I draw with brush two, I want it to completely replace what is under the cursor, be it color, specular or depth. As an example, I draw with a very height-intensive stone brush on a terrain. Then I want to paint grass, completely removing the stone's color, specularity and height. What happens right now is that the depth of both brushes gets mixed together, resulting in a mixture of (in this example) stone and grass - or if the stone's depth value is too high, no grass at all.
As a result, brushes with a very high depth value always paint over others with a low one. I want the ability to completely replace the other brush.
Cheers
