Hi Sebastian,

Ok, that's what I was wondering about.

Of course, I didn't mean to remove the vertex shader, I just meant that
if you're doing things that are not as they are done in the fixed
function vertex processing stage, that could cause problems. If you
don't have a vertex shader then the fixed function pipeline does the
vertex processing, so if you want equivalent results you have to do the
same things as the fixed function pipeline in your vertex shader. So
there are a lot of things that could go wrong there...

As long as you bind them at the root node (the shadowed scene) so that
the uniforms are applied to all the nodes of your graph, that should be
ok. It's still a possible point of failure, so why not just use the same
names and save yourself the trouble?

If you suspect that, you could modify osgShadow::ShadowMap.cpp to try it
out... Sorry I can't help you any more than that...
