yeah sadly the modter planet is not going to be used in the RP. it crashes people's games when cleared and takes like 18 seconds to clear, making it unusable with the planned navigation system.
If someone was able to make modter BRICKS (the modter but it's a brick rather than zones/water), I imagine it would clear a lot faster. If someone is able to do that, please let me know.
I've run tests on modter clearing which are very conflicting. I cleared stacks of modter numbering 22,000 and they clear multiple times faster than my modter planet, which has only ~3,000 modter bricks. I think the use of standard bricks in between each modter brick is whats causing the lag. If I could reverse that effect using brick type modter and then use zones to prop up each brick, that would probably work better and we could proceed with using "modter" planets.
If finding an alternate solution does not work, I'm going to have to use static shape or cuboid planets in order to compensate. But that's a last resort option.
