So, I've never had this problem before but in some of my neighborhoods the view of off-lot terrain in college and vacation neighborhoods is a flat light blue, but not always. The only thing that's changed before this glitch is that I changed to a new computer running Windows 8 and downloaded the UC then added in my old files. I had all kinds of graphics problems initially but found info on Windows 8 stuff, so those got solved. However, this has cropped up a few months after that and I haven't been able to find anything about this so I'm hoping someone can help.
Within college and occasional vacation lots with college student vacationing on them (so when I'm playing a lot) the objects outside the lot (such as houses, neighborhood decorations) show up, including some things that are underground like stairs, but the terrain is a flat light blue.
Sometimes it will be fine when I'm moving the camera, but revert to blue when the camera is stationary. Even on the same lots, it doesn't happen every time I play. It has occasionally happened on vacation lots when I sent college students on vacation, but it mostly happens on college lots, and occasionally the terrain in the college neighborhood view is blue. It doesn't happen at all in the main neighborhood, and I've had this happen in two completely different neighborhood saves with different college templates. I've tried changing view distance and neighborhood object settings, but the only thing that affects it is setting view distance to none, which is really just covering up the problem instead of fixing it.
I can't figure out what the common denominator is and I'm kind of pulling my hair out because it makes my pictures look terrible when it happens and I'm afraid it's a sign of corruption. I have no recent CC or mod downloads (going back to before I switched computers), though I do have plenty of both. Any ideas?
