UE4 Chaos Object Falling Through Other Static Meshes

I was able to figure out #1, enabling the Floor and increasing its value on the ChaosSolverActor in the scene until it mimics where the floor is; it feels a bit artificial but it looks okay. For #2, adding the static mesh simulation on my floor mesh makes the player and other static meshes fall through it. Is there a simple setting to resolve that?

Also do you know how to make it so the broken chaos pieces don’t jump and jitter so much when hitting each other and other static simulated meshes?

Thank you.
