Here is what I have got so far. I am applying a texture to my level geometry ex: "brickwall". Set flag to flat. Extract texture from wad and save as "brickwall.tga" in my work folder. I use a ??heightmap?? i think it is called, and name it something like "heightbrick.tga" and save it to my work folder. I dont apply them to anything just save them in my work folder. Then I change the script to reflect the names of the "sprites" i have just saved to my folder. Then the amazing happens....NOTHING. Please, what am I doing wrong? I am trying to get a dot3bumpmapping shader to work.
