Why i can’t fall? help pls

A Union’s CollisionFidelity property is usually not accurate when on Default. Change its CollisionFidelity property to PreciseConvexDecomposition.


You’re probably better off not using a Union in this instance. Making this out of Parts would probably be much better on performance, have much more accurate collision geometry, and doesn’t have the risk of corrupting like some Unions do.

Save yourself the frustration. Just make the hole out of Parts.
