However, I have to ask a few questions:
1. Is the floor a tile/print plate floor.
2. Does the interior's walls have the same color as the exterior's
3. Any print plates on ceiling?
IDK, just wanted to know.
BTW, to make the floors thicker, a good way to is to have it 3 plates thick. One is the floor of second floor, one is basically support, and last one is ceiling of 1st floor. So, yeah.
