I made this renders two days ago, for now room has changed a little, but the concept remains the same.

1. I want make version without shadows on the floor, it will be great. Since you will be able to disable or move large objects like a bed, horse, etc.

2. Also I want to make handcuffs.

3. The most boring part - bake it and port to Unity :(
That's the plan.

Floor atlas. Unfortunately, this texture requires 2200 samples for good quality, each such texture takes a lot of time (40-50 min) thus I'll spend 3-5 days just for baking.
