Some notes:
*Compound should be applied to an empty polymesh with a non-simulated ICE Tree
*Detail can be set to 0 if simple rocks are good enough
*UniqueRocks slow down the compound more than TotalRocks.
*Size, position and orientation are randomized regardless of UniqueRocks: even 1 unique rock gives a lot of variation.
*Due to how I've wired it up, TotalRocks is only an estimate. This could be improved.
*I have not added UVs
