shader question

Hey there,

I posted this question in the shader forum:

http://www.opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=402305#Post402305

As it seems that no one has an answer I try again here.

Yes, of course a shader can react on spot lights. The fastest method uses vertex lighting: calculate the angle to the spot light center ray, and dim the light when the angle is bigger than the cone angle. The center ray is given by vecLightDir.

Thanks for your answer ... I'll try to figure out how to modify the shader to our needs.
