I'm using rigid bodies with complex compound shape (hundreds of box shapes alligned to uniform grid).
What best compound shape for this case?
I've tried hkpBvCompressedMeshShape, but it's quite slow in narrow phase (~20ms)
hkpMoppBvTreeShape is faster in narrow phase (~5-10ms), but when object is moving in empty space (no other objects at all), it's quite slow (~5-10ms). Why is Mopp slow when it's just moving?
hkpStaticCompoundShape should not be used at all for dynamic bodies, and indeed, it's very slow in narrow phase (peaks to ~50ms).
Thank you for any help.
Additionally, what's good shape for dynamic rigid bodies with collision mesh ~1000K triangles?
I've already read user guide topic Creating Physics Objects and other topics about Mopp and compressed mesh shape.
