Summary0000052: Block colliders are added to the sparse grid multiple times
Description

The physics shape for grids is divided up into GridCellSize^3 cells (6 for large grid, 12 for small grid), with blocks getting added to any grid cells they intersect with. Because of this blocks that take up more than a single coordinate on the grid can end up getting added to the sparse grid shape multiple times. When colliding with voxels especially this can easily cause a 4x slowdown.

A possible fix is to introduce LODs to the grid cells, where larger blocks are put into larger cells. More testing is require to ensure this actually performs well.

Steps To Reproduce

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