Been using the space bar to pick up contours on a mesh but half way through it won't let me do it. Is this the polygon count thing....if so, is there a work around?
Can you show screenshots that show how you are doing this?
I would also be interested to see your settings in the Mesh Settings Dialog and the Info Box as well. These may give a clue to the origin of the problem.
Are you able to manually add contours?
I think you're right that it might be corrupted. We couldn't find a quick fix or work around and we don't need that mesh anymore so all good until it happens again...
