I've tried to cover a sphere with a partially transparent png image with
PoVRay 3.1e. That gives nice results - except for the shadow of the
sphere. The shadow is completely dark, i.e. it has no bright "holes" which
should result from the transparent parts of the texture.
Is that a bug in PoVRay or have I missed something?
Thanks in advance,
