We have a new mapping system that's standalone. turning off map generation in opensim.ini and the new system runs outside of opensim and uses SixLabors.ImageSharp. This solves some GC issues i've noticed doesn't torque the opensim region server.
it's a relief map with height better represented than warp. here's a comparison. note that the region in the warp3d map is actually mostly grass not sand so warp3d is off a bit i suppose?
currently in dev i will be moving new mapping system to holoneon grid later today
