Models/curves etc look fine so it doesn’t prevent anything being created, but it’s a distraction, so does anyone know if there’s a solution to this problem?
I accidentally found the solution. I’d set my max clipping distance to be very high by default. I’ve had a tendency to work with very large scenes, or import models that happen to be very far from the origin, so a large clipping distance was useful to me.
However, I recently imported a high detail object and saw rendering errors in it. I reduced the max clip distance on a hunch, which solved the model’s rendering problems and also fixed the grid.
