For some weird reason, whenever I try to navigate in Houdini/Solaris, I can only see the HDRI studio image that I have set to my Dome light. This is driving me crazy, and cannot figure this one out. I even created a new camera, and the problem still persists. is it some setting I may have set that is causing this?

Please see the attached, and thank you for your help.

That was very strange. It was one of the lights in my scene that was causing this issue, once I deleted it I can once again navigate as intended. Can clipping on a light cause such an issue?

In the viewport, press d for display options, in the Background tab uncheck "Display Environment Lights as Background".

Thank you, Tanto

I will have to play around with that option checked/unchecked to see if this happens again.
