i have an idea about boosting performance on the maps... how about creating an underground fence in 0xygen 50 meters long and 50 meters deep (starting from 1 or half meters underground), so that it sticks to the terrain... and setting up on it cannoclude 1, that should disable the engine from drawing any objects behind it... done a test just 5 minutes ago and the GROUND DOES NOT cull the objects you dont see...
Id like to do it myself but my o2 wont start, it worked fine a few days ago now it pops up an error (the viewer starts ok), tryied to reinstall, wont work, downloaded from the net again wont work...
