How do I open a .CONTROLLER file?

Drop a .CONTROLLER file onto Analyser at https://lab.valjdakosta.com/ and it opens directly in your browser - no upload, no account and no software to install. Open Unity game-engine assets in the browser. Unity serialises scenes (.unity), prefabs, Animator Controllers (.controller), animation clips (.anim), materials (.mat), physics materials (.physicsMaterial2D) and other assets (.asset) as a YAML object stream, with a .meta importer record (carrying the asset GUID) beside every file. Analyser splits the object documents and reads each - a scene's GameObjects and component-type breakdown (Transform, SpriteRenderer, colliders, scripts), an animation's sample rate and curves, a controller's layers and states, a material's friction and bounciness, and a .meta's GUID and importer.

Can I open a .CONTROLLER file online for free?

Yes. Analyser is a free online .CONTROLLER opener and viewer that runs entirely in your browser - your .CONTROLLER file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.

What is a .CONTROLLER file?

CONTROLLER is a Unity Animator Controller - the state machine that drives an object’s animations, with layers, states and transitions. Created and opened by Unity.

Did you know: The Animator Controller is a visual state machine: states are animation clips and the arrows between them are transition conditions.
Analyser handles .CONTROLLER alongside related formats such as .UNITY, .PREFAB, .ASSET and more.
In Analyser's format library, .CONTROLLER sits in the Games category.
