Hello,
I have a problem that I cant solve. I made a cube and a plane.
I set the cube so that it cast a shadow. Why the shadow goes though the plane?

I add a picture to show the problem. I apologize for my bad english.

I'm guessing it's because the shadow is being applied to the texture channel of the object. Because the object is infinitely thin, you'll see the texture of the shadow on both sides.

The quick fix would be to use a box instead of a plain, and then scale the box to be very thin.

Indeed, the plain there is a series of pixels taken from the shadowed texture projected by the camera; regardless of which side you look at the plain it will have to use one texture for both sides which means a shadow on both sides.
