Thanks for the reply. I actually did find that post while searching before I started this thread. It was helpful, certainly. At this point I’m guessing it’s simply my computer that isn’t able to handle these types of calculations all that well. Sucks, 'cause now when paths are all built, leaving them visible in the editor makes it impossible for me to use anything. The editor window just sits there, frozen in time. Lagged out.
I definitely turned off the automatic navmesh rebuilding, which at least made it so I could work at a regular pace again. But as soon as paths are visible, I’m donezo. Guessing I need to upgrade, but I can’t afford to do so right now =(
