We saw that VAR regions do not scale well, and that normal operations (such as maptile generation, or persistence) could make the larger regions unusable for minutes at a time. Unfortunately, OpenSimulator only provides mechanisms for loading a standard oar into a VAR region. I could not find any mechanism for saving a tile out of a VAR region. So I wrote one.<o:p></o:p></span></p><p style='background:white'><span style='font-family:"Calibri",sans-serif;color:black'><o:p> </o:p></span></p><p style='background:white'><span style='font-family:"Calibri",sans-serif;color:black'>The scripts are released under MIT, and are available at <a href="https://github.com/M-O-S-E-S/opensim-oar-utilities" title="https://github.com/M-O-S-E-S/opensim-oar-utilities
