There are a bunch of really cool normal map textures included with the program now. However, we've found it impossible to paint on different channels at the same time when using a normal map texture. The painting works, but the alpha of the brush is not the same as the alpha of the normal map texture. So you always get something like the screenshot I attached. All information is painted, but everything that's not the normal information just follows the alpha of the brush.
So is there a way to force a brush to take the alpha information from the normal map texture? [ Invalid YouTube link ]
