The start/end quaternion must be normalized

Does anyone know a fix for this.

I get this error every time I try and play my keyframes.

This is how the animation player is set up.

I’ve managed to quaternion both the start and end but I can’t put keyframes between for the actual animation

I’ve yet to encounter this problem in my work, but here are some resources I found for you:

**Describe the project you are working on:** 3D animated character **Describ…e the problem or limitation you are having in your project:** Creating new *3D Transfrom Track* in Godot AnimationPlayer, setting rotation is **not usable** for hand-editing, when it presented in GUI. Rotation ask for normalized Quat, it make impossible to edit it in GUI. if set not normalized Quat (as for example, someone may expect it rotation by Rad-s) result it error ``` The end quaternion must be normalized. The start quaternion must be normalized. ``` from [docs class-animation](https://docs.godotengine.org/en/stable/classes/class_animation.html#class-animation) `int transform_track_insert_key ( int track_idx, float time, Vector3 location, Quat rotation, Vector3 scale )` **Describe the feature / enhancement and how it helps to overcome the problem or limitation:** I ask to make in animation *3D Transfrom Track*-editing **GUI** Rotation by angles or rad, to make it useful for hand-editing.

Thanks for the resources! Looking into still but hopefully getting closer.

Found the solution.

All it took was enabling the little pencil on the right of rotation, and then changing the values on Temporary Eular.

Good job! I’m glad it worked out.
