I'll look into it, thanks for the hint.

I'm playing around with multipass rendering too, thanks for your very insightful posts and examples.

Regarding circusmonkey's approach of exporting out parameters from the shaders: how do you handle scenes with many shaders? For example, if you want occlusion,id,shadow passes, than all the shaders need to have those exports in them, if I understand the method correctly.

Is there a way to generate/edit these exports from a single place, rather than having them in all shaders? Would that be something that you could do with a pre-render script?

Thanks!

Cool. Thanks for again for your help.
