Int32	BucketsCount = 16
	The amount of buckets used in the broad phase, which are resolved in parallel. Use a reasonable amount according to how many physics entries (colliders) you have.

	Regular queries (overlaps and raycasts) use a stabbing approach for checking as few entries as possible in the buckets subdivisions.

Int32	WorldSize = 256
	The physics scene size in the bucketing axis. The broad phase is clamped by a bounding box of all physics entries between -WorldSize/2 to WorldSize/2. It is therefore crucial to ensure the world is big enough to encompass all entities. If an entity is outside the world, it will cost you performance as it is added to either the first or last bucket. Everything outside the bounding box is considered to be at the world's edge, from the physics engine perspective, which will result in false collision candidates. In the non bucketing axis, the physics world is only limited by the value range of FP.UsableMin to FP.UsableMax. More...
