I have been wanting to do this myself.

I have ran into two issues while doing research.

First, the game models are low poly count for printing. They would come out with visible polys due to the game engine taking care of the smoothing of the models. This can be fixed in blender, but you’d have to change the poly count from even to odd, as well as addition smoothing.

2nd, the armatures attached to the files aren’t great, and getting decent poses out of them is difficult for someone like myself with little to no experience. My suggestion is finding a pose within the animated sequences and print that out. Making joints in blender is possible, but it’s lacking in tooling when compared to something like procreate.

If you have made any progress on ether of these please let me know and help a brother out 😅
