I chose the Visualization scene "Cleanroom 2" from the standard system scenes in NX8.5. It showed up initially, but as I was changing some settings, it has disappeared, replaced with a light grey flat colour.
I noticed that when I toggle True Shading off, the Cleanroom 2 image appears for a split second, but apart from that, all I'm seeing is a plain grey colour.
I've tried going through all the obvious settings under Visualization Preferences, and Scene Editing etc, but as I'm a noob to the visualisation tools in NX, I can't figure it out.
Can somebody please suggest how I can get the image to show? And also any suggestions of relevant forums or posts to level up my visualization skills would be much appreciated.
