Hey Frank, Thanks man! Yeah, this'll be the convex hull thing - they can't model concave shapes. Currently you have to split concave's up into roughly convex parts and then, in the case of dynamics shapes, set them up as compound so they stick together as one. If you switch on the solver troubleshooting overlays you should see a rough approximation to the physics world proxy shape. In the future there are avenues I can look into with respect to making this convex decomposition happen programmatically (although currently there's some hardcoded assumptions about 1-1 Nuke geo object to physics shape which have to be completely torn out to allow for this or fracture type bodies).
In the case where you're using Nuke shapes, then obviously its slightly less easily to split up into sub sections, so instead I've taken your cylinder and, from the point of view of the physics scene, replaced it with a series of box collision shapes, forming the sides of a cube (except the top). These are set to not render (so they just offer a place for the sphere to drop into). The cylinder I've then merged in after the solver node, so it appears in your render wrapped around where the sphere lands.
