Hi Yuri,
The problems with shadows not appearing and the floor being red are two
completely separate things. I bet your floor is red because you are
loading a model which is red. The floor in shadows.c does not have its own
geostate, so it will inherit the color of the last geostate which was
applied when rendring the model. Put a geostate on the floor geostate
which has a material specified and model colors will no longer bleed into
the floor.
I'm still looking into why there are no shadows, I'll post again when I
know.
