Okay, it works well with some M2's, not WMOs, may I please know why? I've tried everything, I can use ALT on some M2s, just not WMOs... I can turn a tree on its side. I can turn a banner lay down, I just can't do that to a building. Please help, thanks.
[EDIT] I am also using the 'Copy from WoW Model Viewer'. Tell me if I'm doing anything wrong, thanks.
