Hey,
I'm wondered that it is not possible to change a Shader Value (SetValue) of an Effect which was already bound.. In OpenGL it is possible to update any Uniform Variable even the shader still enabled. I think in some reasons this could cause a lot of CPU load. In my example I have a Scene graph including some meshes and each mesh haves a couble of subs with different materials. So I need to load (begin) and disable the shader for each sub, because of changing material and matrix... Same for my lighting pipeline.
I'm right or doing something wrong ?
Cheers,
Thomas
