The shading on the paper doll seems to be broken, sometimes parts become really dark. A suggestion to fix this would be to use the same rendering for the paper doll as the one used in the vanilla inventory.

Hi! this is a known, issue. In fact, the doll overlay uses the same rendering as in the inventory. I haven't been able to find the cause of this difference yet.

Hi, I’ve checked and found that the shaders are set up for 3D rendering on InventoryScreen. So I made a small change to support flat shading and it seems to work. Here is a test movie.

I will create a new PR for this fix after some testing.
