Alright after screwing around with my physics cage I've finally got things moving again! Now I can actually see things interacting with each other, but it still needs some work. Currently the mesh kinda deflates when being pushed, but thats a small thing to change at the end.
Now I'm going to finish the animation loop and then change the physics until they look good. I don't know how long it'll take to render, but my PC should be able to handle this pretty well.
Hopefully things should be done in a week if I focus and dedicate my free time to this, but my job comes first along with other important things in my life.
