Basically, I (nor J-Dawg) haven't been able to successfully generate terrain meshes for AltonDowntownWorld, and it definitely needs it. Playing through it without it would be disappointing, as you wouldn't be able to see in front of yourself more then 2 or 3 cells. The problem is that I HAVE been able to generate LOD before, but for a smaller worldspace, AltonPlaneDiscovery. This worldspace is only 65 chunks, but still. At one point, it worked.
So anyway, I'd be willing to pay anybody that could successfully generate terrain mesh LOD for me. I could pay you via Paypal, build you a small mod once I'm done with Alton, or whatever. You'd also earn a spot in the credits video that will roll at the end of Alton's main quest, obviously. Keep in mind that LOD generation, especially on such a large worldspace, takes time. We're talking about probably around a week of non-stop generation. So make sure you're willing to keep your computer on and running, and a well-spec'd computer would be preferable (as it would have the highest chance of doing so successfully).
So thanks, post below or PM me if you'd be willing to at least give it a try.
