Yes you can, there is a sample on matrox's site that shows how.

Hi

Does anyone know offhand if Bump mapping can be done on semi-transparent alpha-blended textures? The docs seem to treat the two as seperate entites, and unless I missed something don't say that you CAN'T do it, but its having weird update problems on my Millennium G400 that go away if I make it a normal, nonalpha texture.

Thanks a ton

Thanks.. I must have been setting one of the AlphaOP arguments wrong... it works now... looks pretty cool too!
