Current Behavior

Basically, I am using the large boat from the threeboats example provided with crest. My player is a character controller (no rigidbody just a capsule collider), when it is walking into a collider this happens...

The wall it collides with also has no rigidbody so I'm quite confused as to what's going on The wall colliders are a child of the boat so I'm guessing maybe theres some function that gets all colliders possibly? Even then i dont see how the players interaction with it would cause this to happen as both the player and wall have no rigidbody

Expected Behavior

Player's movements don't have an effect on the boats physics

Steps To Reproduce

Open threeboats scene Add "floor" and "wall" box collider to ship Add FPS controller from asset store (character controller with no rigidbody) Control the player on the ship walking into the wall Ship glitches everywhere

If the boat has a rigid body and the collider is a child then it becomes part of the boat's composite collider so it is part of the boat. Having a static collider (the player) on the boat will unlikely work well.

I'll move this to discussions as unlikely a bug.
