Animation PreChecker

Animation PreChecker is a simple Roblox Studio plugin that helps you check animation problems before you submit an avatar item. When making emotes or avatar animations, small errors can be hard to find. A body part may move too far from the HumanoidRootPart, or a foot or hand may move too fast for the avatar item rules. This can take time and slow down the work. With Animation PreChecker, you can select a saved CurveAnimation or KeyframeSequence in Explorer and press one check button. The plugin creates an internal R15 test rig and scans all 15 body parts. It checks whether any part. The result is shown in a clean list with the time, body part, error type, value, and limit. This makes it easier to find the problem area, fix the animation, save again, and check again. This plugin is not an official Roblox validator, but it is useful for catching common animation issues earlier and making the upload process smoother.
