Do you have any ideas how to make such thing:
I'm doing one pass for every light in the scene and I have stencil shadows. I want to add transparent obiects that are affected by shadows.
I'm making first pass for depth only (and ambient light) so I cannot modify depth by transparent obiects, because after that I wouldn't be possible to render obiects behind transparent one. And if I render transparent obiect and in next pass for next light I render obiect behind this transparent one won't be visible.
I can render transparent obiects after rendering all lights, but this needs to render shadow volumes one more time for every light.
I dont't have any idea so I think I'm gonna make transparent obiects without shadows but I'm very curious how to make it with shadows without rendering volumes two times.
