Here's something really important ,probably trivial, to which I haven't found a solution:
While I'm painting with smart material .. I understood only the heightmap is taken in account. Like this:
But what if need to have both the depth given by the heightmap in the smart material, AND the depth of my alpha brush? To obtain something like this. Which I obtained by painting the diffuse ,normal, specular and then painted over the depth of the alpha brush, after closing the smart material. How to do it all in one stroke?
