Your suggestion definitely worked!
Also, is there map files available for kh2fm like how kh2 were?

I'd love to explore the fm rooms using the map viewer.

That depends which map viewer you're using. I assume you mean the one in kkdf2's expack1h, but I've run it on my Windows 10 and it handles just fine. But if that doesn't work for you, it has a function to export the maps into .blend files for viewing in Blender. If that still doesn't work, Revelati...

Hey guys, I figured you MIGHT have an answer to this, but for some reason on Windows 10 the map viewer bugs out hardcore. When I go to rotate the camera within the map it freaks out and it only goes up and down super fast. I used it for when I build the maps within MC, but it has become hard to use....
