I updated the door logic and put a proper texture.
I didn’t paint this. As I said in an old post, I’m trying to mainly focus on modeling the characters. Most of the other assets (beside the crates, few weapons and the spawning capsule) are from free or paid packs. This one is a free textured mesh you can find on the Unity asset store (here). But instead of using it as a piece of the floor I made a rotating door out of it : easy and cheap.
Maybe I’ll edit the texture to give it a kind of “flat” low poly style. Later.
