Hi, It seems that Havok’s implementation of PhysicsShapeCylinder is broken; depending on the ratio between cylinder length and diameter, the actual collision shape used becomes an infinitely-thin planar circle. See this playground: https://playground.babylonjs.com/#0VS3BE#3 Turn on the Physics Hel…

So, I think there’s two separate problems here; one is the debug display geometry; internally, physics doesn’t store the “real” input vertices, so we reconstruct the debug geometry from the physics shape; we chose to use a “fast-but-slightly-inaccurate” algorithm here, which ends up with slightly sm…

You probably need to increase the diameter and height of the cylinder.
I have tried similar samples before.
