Hey paul,
I think I found a bug with the general visibility settings. In the materials tab when I select a mesh. If I change the values more than once on General visibility from 1 to 0 or 0 to 1.
I can't change the value again. It switches my cursor over to subdivision it will not let me change the value at all in general visibility.
I would have to click off the current mash and on to another and go back to the previous Mash to change the general visibility settings.
Or if I change the general visibility settings and go over and change the subdivision level settings. I cannot go back to General visibility and change its settings at all.
Again I have to click off the current mash and on to another and go back to the previous Mash to change the general visibility settings.
I know it sounds strange to go through these settings like this. But I tend to test out techniques and strategies a lot.
And I'm really fast at troubleshooting and changing settings.
