Thanks!! :D
i was inspired by your twitter so i added occulsion culling to creepyface too! You will see that in 1.9!
Cool!! It's really easy to implement, all you have to do is go to Windows > Rendering > Occlusion Culling, and just hit bake!
I knew that but the maze looks like it is one floor when i am in the visualation tab which i find funny
lol
