Hi,

i am trying to fade a bumpmapped surface towards the edge for cards without arbvp & fp. The bumpmapping is simple dot3, using tangentspace light in primary color. and a normalmap.

Is it possible to access the secondary color component within the texture environment combine? I checked the specs for ARB_tex_env_combine and EXT_secondary_color, but no hints if it's possible or not.

Thank you very much.

regards,
Stephan

You didn't really search. http://oss.sgi.com/projects/ogl-sample/registry/ARB/texture_env_combine.txt
Find "secondary" on that page, first hit issue 6.
Answer is "Not in this extension."
