A purely cube-based system would certainly be easiest but, unfortunately, I plan on having non-cubic blocks such as stairs and wedges and weapons and only a couple of blocks will actually be perfect cubes. Do you know if there’s any difference between HISMCs and regular ISMCs other than adding LODs? So far, there seems to be no performance difference between HISMC and regular ISMC. I can get some excellent performance with instancing, but it really suffers once the structure moves at all. Do you have any recommendations for speeding up the transforms of all the instances? It’s definitely faster than individual components but it’s still too slow for what I need.
