Jan 2nd update
I've gotten multiple features needed for the boss fight working. Made a turret with a locked angle constraint, polished how the hit effects work (they'll spawn on the model in the place that you hit them in while rotated at the correct angle) instead of just a static location/rotation attached to the spine bone and got the blood splatter effect working. Also, the platform moves properly. I'm still working on character portraits and adjusting all the lighting in the locations. This time around I'd also like to bake the lighting for optimization. Also importing from blender needs some streamlining, right now I'm doing a bunch of manual stuff each time I import from Blender, so that needs to be sped up.
