Create collision geometry for ground

“

- [Narrator] Now we're going to look at how to set up the ground geometry for proper collision representation, 'cause obviously there are very different kinds of geometry, the ground and then the shell that we just set up, and these are good examples of looking at two very different ways to do this process. So if we go into our Scene Sim dynamics dode, we take a look at our ground, I'm going to pull up the parameters here. First, I'll go to the physical tab, I'll change the bounce to zero. Then I'm going to go to my collisions tab, under the RBD solver I'm going to turn off volume-based collisions, because we're not using the RBD solver, we're using the Bullet solver, so we want that, and let's turn on "show guide geometry" and right off the bat you can see the problem we were having before, because this creates a convex hole around our more complex organic shape, which works in some scenarios where we have things that a convex hole works for, but for geometry like this that's not…
