Join Joel Bradley for an in-depth discussion in this video Working with the mesh collision shape, part of Blender: Creating Rigid Body Simulations (2013).
Having clarified in our minds the…difference between concave and convex meshes.…And having identified that this difference is the cause of…one of the problems we are currently experiencing, inside our simulation.…Namely our active rigid bodies not dropping into our tank object/g.…We can now go ahead and select the tank geometry, and jump…straight into the collision shape controls over in the physics properties tab.…To see how we…can start to fix things.…The reason we are experiencing this…problem, is because when Blender creates an…active rigid body, it sets the collision shape by default to Convex Hull.…
As our tank geometry is clearly concave in nature, having this big…hollow sensor, we obviously need a collision shape that can work with it.…Unfortunately, as we take a look at the list of…available choices, pretty much every option we see from Box…up to Convex Hull, pertain to convex shapes, although…this is not necessarily a bad thing, as it…means we only need to remember one available option…for working with concave shapes, which would be mesh/g.…
