Create collision geometry for shell

“

- [Teacher] So now I've got our shell and our ground combined together in our scene sim dynamics network, and what we're going to focus on now is improving the quality of the collision representation geometry of our shell. Okay, so let's go into our SCENE_SIM. I'm going to go up to our Shell. Let's zoom into this guy a little bit. The PKG in my parameters. So off the bat, I know that I want the physical parameters just to be different so I'm going to change its density to 5,000 and it's balance to .1. Next I'll go to the Bullet tab. We'll turn off Display Geometry and we'll look at the guide geometry. So, right off the bat, the collision padding is too much, you can see there is quite a lot of space between these that I've made. So I'm going to change that from .02 to .002. Alright, so that better fits the geometry. We still have an issue here, because mainly with these pieces that have concavity to them, if I hit the W key to turn on the wire frame view you can see like with this…
