Summary0000051: Poor grid-voxel collision performance for large multi-shape blocks
Description

Currently the grid physics shape component produces a havok shape that's a sparse grid containing mopps, with each mopp containing transform shapes wrapping the block shape or shape list. When the shape wrapped by a HkTransform overlaps a large number of voxel triangles in the midphase it causes an extremely high number of bounding box recalculations.

This can be addressed by flattening shape lists inside each block and then wrapping them in HkConvexTransform or HkConvexTranslate if possible.

Steps To Reproduce

Place the 800mm gun from https://steamcommunity.com/sharedfiles/filedetails/?id=1627544201 near voxels.
