Issue
1.0 issues – cannot see Corona VFB!
Note: this article applies to early 1.x versions of Corona.
Solution
If Corona VFB does not show up when rendering:
1. Go to Render Setup > Common > Common Parameters and make sure that “Rendered Frame Window” in the far bottom is selected.

2. Go to Render Setup > System > Frame Buffer > VFB Settings and make sure that “Type” is set to other than “None”.

Note: this may also solve problems with interactive rendering not working. See: Interactive rendering is not working!
