All what I can say at the moment is that I probably have a problem with gl_Color and vec4 in the recent shaders with my very very old card on my very very old computer. When I comment out alpha or diffuse definitions in default/mat-anim/model-default/reflect.vert the code gives me "varying ... not written" and gl_link errors of course - but all the other shaders like landmass/crop/clouds/bump are still working fine as I can see. Looks like vec3 diffuse is working, vec4 diffuse produce problems. I wonder if this is only related to my rare ati and very rare OSX or if some others have the same problems with recent cvs effects and shaders.
