1. A concise explanation of the problem you're experiencing.
I'm totally confused.
When I set screenSpaceCameraController.enableRotate=flase,the camera stays locked at the current position in 3D.But I can rotate and Tilt the camera.
When I set screenSpaceCameraController.enableTilt=flase, I cannot rotate and Tilt the camera both.
2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.
var myScene = viewer.scene;
myScene.screenSpaceCameraController.enableRotate = false;
myScene.screenSpaceCameraController.enableTilt = false;
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
