Hi All,

I'll like to prepare geometry for shadowmap different from the one that i prepare for rendering.

I would like to generate fur with the face front the current light so the fur silouette will be correct.

Renderman use this tecnique to calculate the correct deep map for any light.

I know that is not possible.. this is just a try :)

Cheers
Renato

Perhaps you could use a volume shader for this purpose?

The idea would be to create a volume shader and only implement CalcTransparency() to see if you can determine from raybits when you would need to occlude shadow rays.
