Comments.Text: That looks like the preview panel is just not opened in your current workspace. Have you tried resetting it under window -> workspace -> reset active workspace (or something along these lines)?

Comments.Text: Yes I tried. The preview panel is fine because it work ok on Compositions without any 3D layers. If I create a new Composition and include a 3D layer it looks fine, but after restarting AE it disappears, only rulers remain in place.

  I just reopened my project and in all compositions that have 3D layers the preview is gone:

  It looks like a bug to me but maybe I'm missing something?
