At least a year ago I created sets of animations for weapons in roblox. They used to work just fine, but I am now having an issue after reuploading the very same animations. They seem to be mirrored, and infuriatingly, this has caused me to lose the original animation and its’ behavior. This is a video of the same animation playing on the old rig I used to use and a new one; the new one reflects how the animation behaves in-game, and was created using the new rig builder.
What is going on here? Is it possible for me to get the old behavior back, or do I have to remake all my animations?
