I've been working on a project for a while, and suddenly I have the problem that my walls (which are cut by the roof) are visible in 3D and Elevation. Changing priority of roof layer over walls doesn't help. In all earlier versions of the file, this is not a problem. If the issue is not priority, what might it be?

See attached screenshots.

The issue could be the Intersection Priority (IP) of the Building Material (BM). It looks like the Wall IP is greater than the Roof, so the Roof is getting cut before the SEO is evaluated.
