Anyway, looks nice. I appreciate your contribution very much! Formerly known as The Matrix - ICQ 170408644 I've been here for much longer than most people think. So where's my "Expert" status?

I don't really know why, but my model that has normal maps applied is very, very dark. Also, are normal maps similar to bump mapping? Any info would be appreciated. Anyway, the shader would look great if the models were lighter, which is probably my fault, not yours. Logan

Anyway, looks nice. I appreciate your contribution very much! It is possible... To convert to ps.1.3... The first thing to do is pass the base_map thru the vertexshader with it's own TEXCOORD (for example, TexCoord1). Then in the pixelshader you will need to sample it using the TexCoord that you output it as from the vertexshader. The texture reads in ps.1.3 (and below?) need seperate Texcoords. I was able to make those changes and compile it for 1.3 and get the same effect as compiled for ps 1.4. Also, I was successful on converting it to ASM, both the vertex and pixelshader, which can help troubleshooting a little. http://steempipe.blogspot.com

I guess I took the scenic route to get there... -Rhuarc I no longer post on these forums, keep in touch with me via: Linkedin.com My MSDN blog
