Model rotating with Earth when defining orientation - INERTIAL

Hey Cesium,

I’m seeing that after modifying entity.orientation the model rotates with the Earth, i.e, if the Earth rotates 360 degrees the model also rotates 360 degrees.

Here’s a Cesium Sandbox showing what’s occurring. As you scrub through the timeline you can see that the model is rotating the same way the Earth is rotating.

If you go to line 73 of the sandbox, comment out the line and re-run you can see that the model doesn’t rotate with the Earth anymore.

Is this the correct way in modifying the entity orientation? If not how should it be done?
