Yeah sivan i am a bit sceptical about the lod in trial version to , it sounds to me a bit like you are thinking about doing a navmesh for your Path finder well it would be really cool if you could do it and keep your insane amount of entities doing theire thing .. Well yes i have functions that would displau the navmesh by code.. Im now looking at adding some advanced pathfinding functions to use the exclude include filters and max path points to .
