Has anyone developed a shader that does the first pass as a bump map and a second pass as a transparency? We been trying to assign a bump map to a irregular object, and the first pass we got the bump map to be placed on it, but want everything that is black be transparent, like the overlay flag used by A6.

So we thought we have to do to passes but it still shows the black.

If you send me the effect code (or post more details on the effect itself), I may be able to help you with your problem. Anyway, it would be much faster to do this via email (mine is Raul3D(at)t-online(dot)de), just write me if it's urgent.
