The rules are simple:
- use only cuboid shapes, you can scale them to long sticks, or squash them to flat boards, just keep them rectangular(or square) .
- use 10 or less cubes.
- the ground plane is free
- you can rotate them any way you'd like, but they cannot intersect each other.
- default grey materials only.
- keep the lighting generic, AO and soft lights are fine.
