This is one simple way I've mapped boxes or flat surfaces at different angles.
Create the surface slightly larger than what's needed. Difference the surface
with plane or planes that match the angles needed. The planes would carry the
material and transferred the image_map or material to the differenced shape.
Each rotated plane can have its own material, so a 6-sided cube could have 6
materials.
Hope this help,
Mike.
