Occlusion effect is invalid for projector,
When I use the projector in unity, I find that the occlusion effect is invalid for projector. It mains when I use the projector to get caustics, if the land has a gameobject on It, the caustics don't disappear in shadow. I change the shader of the projector by adding SHADOW_COORDS and TRANSFER_SHADOW and TRANDOW_ATTENUATION to get the value in every pixel, but it's 1. The gameobject and the land all are "1"!
Now I can't realize the effect that there are no caustics in shadow. Who can help me, Thank you.
