I've used TLblocker1spotlight.sl from the renderman.org site as the
basis for a shader I'm working on. It's a light that only casts
shadows. It uses a shadow map, and it works great, so I wanted to add
a texture map using the above shader as reference as to how to do it.
The problem is, that when the camera moves, so does the patter the
blocker creates. it rotates around it's axis.
I'm using 3delight on OS-X.
