The Threepeat Animation Importer (All external marketplaces and sources)* is an automated tool to make importing humanoid animations from external sources much faster and easier.

Features:

Persistent configuration through config scriptable object and associated Editor Window (Tools -> Threepeat -> Animation Importer)
Right-click menus for Full-detection automated Import and Quick Automatic Import
Automatic configuration of the following:

Removal of T-Pose animations (based on configuration preference)
Renaming animations to match the model prefab name (as Unreal and ActorCore animations come in with "Unreal Take" and "Take 001" as animation names)
Automatic setting of Y- and Y-rotation root motion reference
Automatic animation loop detection
Automatic animation Y-bake detection (starts and ends at same Y root position with total Y traversal within configured thresholds)
Automatic Avatar configuration
Automatic Y-rotation bake detection (For animations who start and end at same Y root rotation)
Optional Automatic Mirroring of all imported animations

Configure entire animations in one click or, if there isn't an existing preset, use our automated animation evaluator to automatically set parameters (rotation baking, loop, y baking, etc)

* - This product has no affiliation with Unreal, Mixamo, or ActorCore and implies no sponsorship or connection to these products or rights-holding entities. We just love their animations and want Unity users to be able to import them faster!
