Hi,
GL_TEXTURE1 doesn't work on my ATI 9600, but it works on my ATI 9800.
The code is just the following:
glActiveTexture(GL_TEXTURE1);
glEnable(GL_TEXTURE_2D);
glEnable(GL_TEXTURE_GEN_S);
glEnable(GL_TEXTURE_GEN_T);
glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_SPHERE_MAP);
glTexGeni(GL_T, GL_TEXTURE_GEN_MODE, GL_SPHERE_MAP);
glBindTexture(GL_TEXTURE_2D, texture[0]);
// draw a QUAD...
GL_TEXTURE1 works on my ATI 9800 but it doesn't work on my ATI 9600.
In order to make it work on my ATI 9600 I have to use the texture zero.
glActiveTexture(GL_TEXTURE0);
Does anyone know why?
Best Regards
