Hello, could you please help me with this: My mesh won’t rotate along y axis for some reason. ```auto Babylon test page

Exported meshes usually(always?) have rotationQuaternions. You can either null them out with mesh.rotationQuaternion = null and then use the .rotation property Or you can use the rotate function [Mesh | Babylon.js Documentation](https://doc.babylonjs.com/typedoc/classes/babylon.mesh#rotate) Or manually rotate the quaternion. ---

I don’t know why but the mesh is still not rotating after adding: ```auto scene.getMeshByName(name).rotationQuaternion = null; ``` ---

Thanks but after adding ```auto scene.getMeshByName(name).rotationQuaternion = null; ``` it still doesn’t rotate. ---

See if this helps: myMesh1.rotate(BABYLON.Vector3.Up(), -Math.PI / 2); ---

A repro in the playground would help us catch it in no time. ---

It’s spinning now By opening the console you would have seen your error.: getMeshByName(name). Scene was missing. Also the rotationQuaternion can be outside the loop registerBeforeRender And you can directly use newMeshes [0] rather than getMeshByName.
