I’m facing this problem. How to fix it?
You probably have two or more faces directly on top of each other. It is called z-fighting.
That’s called Z-fighting. It’s caused by two faces on the same plane. Get rid of one of them and you’ll fix the problem.
I’d suggest moving the group with the image down by a few millimeters, but if you are using the imagery for tracing, then you should probably just assign the imagery to a different layer so you can toggle the visibility on/off as necessary.
In a case of tracing purpose, turning on X-ray mode works a bit better than turning layers on and off IMO.
Though you should put them into different layers eventually.
‘Add Location’ already introduces two new layers:
- Location Snapshot and
- Location Terrain
in which snapshot, resp. terrain are placed (= assigned to these layers).
And it activates the icon ‘Toggle Terrain’ as well.
