Hello, We recently decided to switch to quaternions for all the object in our scene in order to make it work with the gizmo. But we still use Euler angle as inputs, so we use the classic function RotationYawPitchRoll in order to go from Euler angles to quaternion and we observe that we don’t have a…

Ok I managed to make it work! My problem was that i used the mesh rotation as argument of RotationYawPitchRoll like that: mesh.rotationQuaternion = BABYLON.Quaternion.RotationYawPitchRoll(mesh.rotation.y, mesh.rotation.x, mesh.rotation.z); But it seems that mesh.rotation is set to Vector.Zero aft…

Yep, once rotationQuaternion is used rotation will not get updated automatically (this is for performance reasons) but I think you can do it manually.

Should I prefer using rotation or rotationQuaternion for TransformNodes?
