I retargeted a new NPC to use the default skeleton and it broke all my anims and skeletons are now T-posing, I tried to close UE4 to avoid saving the changes but must have clicked save instead of don’t save… is there anyway to force UE4 to load a previous version of the project or have I just lost 6 months of hard work?
In your project folder ( looking from Windows ), there is an Autosaves folder. You might be able to find something useful in there. You need to try restoring from there into your content folder, while your project is NOT open. Be careful and keep copies of stuff, so things don’t get worse.
