Steempipe, in your tutorial it states:
It is assumed that you have a general knowledge of:
-Producing a Normalmap in exterior software

I do not. is there a tutorial for this somewhere? I have not found it. Tried "normalmap" in the search, but found nothing on how to make them with exterior software. Does anyone know where to point me to? Thanks.

NEVERMIND! found this webpage. http://www.snarkpit.net/editing.php?page=tutorials&game=HL2&id=186
it says something abouit compiling the two textures with vtex.exe. What is that? do i need it or do we do something different with the two textures in Gstudio?
