but wait, what about collision
Simplified with trapezoids and such. It's kind of a issue for 6 studs behind and then on the height.
I managed to sort of trick the system by splitting the collision between 2 bricks.
The build itself os 104x70. The brick consists of 2 bricks, one which is the main building with the base and the other which handles glowing windows. The building itself is like 64x64 meanwhile the one that handles the windows is 64x40, putting next to each other I got a 104x64 of perfect collision, but no more than that, and vertical collision is still an issue.
In order for 100% perfect collision (not brick per brick or such, but actually functional), the whole building would need to consist of 5 bricks. I don't think it's worth it though since those bricks would, without any doubt, end up invisible nonetheless as except collision they wouldn't have any use.
