ChaseCamera can't look up!

Hello everyone !

I am new with JME and I try using a ChaseCamera. It works with no issues but the camera doesn’t go under the Y of the model it is tracing.

I also try to disable drag-to-rotate function but my mouse’s cursor always get out of the screen. How can I make the cursor invisible and always put it at the center of the screen ?

Is there any way to do that with the ChaseCamera ?

Thanks !
