I used the wrong renderer for the exe version. I just updated it so hopefully that fixes the camera issues. It is a bit concerning to hear about though since I never encountered an issue like that while working on this. If you have time, could you send a video of the camera flickering so I can see what caused it?
Glad to year you liked the models, this was the first time I've used blender for a game, so I really had no idea if what I was making was actually good.
And yeah, I'm not happy with the connections UI either. The code for that alone came close to completely destroying the game.
