solved Rotation of an imported mesh

[Flomotion]

I want to animate the rotation of some objects from an imported mesh. But the rotation behaves very different on an imported object.

How can I get this to work the same as it works on native objects.

To illustrate I made a playground where the cube above the cat behaves as it should. They both have the same keyframes.:

I hope someone knows,

thanks!

I am not sure about the root cause, but if you animate a parent then it works, so maybe that helps?

** edit: yours works if you set:

cat.rotationQuaternion = null;

Use one or the other - that's a gotcha that gets everybody!  Use animation type: BABYLON.Animation.ANIMATIONTYPE_QUATERNION otherwise - if you need an example ask.

The object is using quaternion so you would need to animate rotationQuaternion and not the rotation:

I invalidate the rotationQuaternion on cat by forcing it to null.

I agree it is not intuitive I ll try to find a good spot in the doc for it.

Thank you both so much!

cat.rotationQuaternion = null;

Easy and perfect solution!
