So I'm having a very strange issue with add-on planes, both flyable and AI. I recently added a GIV (user flyable) and a complete mexican AI package and the aircraft show up as all white, i.e. the textures are not loading. I've checked the CFG files for the GIV and everything checks out fine in my eyes. All the folders are where they should be. The default planes work fine. And yes I do have the latest drivers and all that good stuff, I just built this computer.
Interestingly enough my Air Tran and Alaska Airlines World-of-AI planes show up fine. Those are the only other AI packs I have for now.
I've googled this issue and came up with no results. I've tweaked a lot of settings and have had no luck. Any ideas?
