Being able to edit the quality of terrain would open the possibilities of having extremely large scale smooth terrain maps with much lower CPU, GPU, and Memory usage.
the idea is as simple as changing the voxel size from 4x4x4 to 8x8x8 or 16x16x16.
the use cases would be anything that'd need a very large map, but where terrain quality is secondary. like a flight or ship sim.
of course this would have to be fixed in studio, and read only by scripts.
