You sure this isn't 'normal'? There are examples of this sort of maze 
that are built to intentionally minimize refraction and will as a result 
'always' appear black from the camera location in the real world. Adding 
levels of recursion to it to 'make it work right' is in such cases likely 
wrong anyway.
