Concave polygon shape. Concave polygon shape resource, which can be set into a [PhysicsBody3D] or area. This shape is created by feeding a list of triangles. Note: when used for collision, [ConcavePolygonShape3D] is intended to work with static [PhysicsBody3D] nodes like [StaticBody3D] and will not work with [KinematicBody3D] or [RigidBody3D] with a mode other than Static. https://godotengine.org/asset-library/asset/675 Returns the faces (an array of triangles). Sets the faces (an array of triangles).
