Rotation of ArcRotateCamera not working

Questions
1

Hi everyone,

I am trying to get my ArcRotateCamera’s upVector to face in the -Y direction by setting it to Vector3(0, -1, 0) but for some reason, it doesn’t work. I’ve tried negative values for the x and z values and they work fine. It doesn’t give an error but also doesn’t display anything. I thought by setting noRotationConstraint = true, the issue would be solved but it no luck. I have a playground set up:

If anyone can provide me with a solution, I’d really appreciate it. Thanks in advance.
