I have a model designed in Blender of a spaceship hallway. In all modes except for Render it appears as designed. However when I switch to Render mode the walls vanish.
Wireframe view:
Solid view:
Rendered View:
More unusual, when I rotate the image while in Rendered mode, I can see the walls but only if they are exactly between the camera and the rear of the object. It's hard to explain, but I uploaded a short video of the phenomenon: http://www.youtube.com/watch?v=3YIuppScj9g
I'm uncertain what I did to cause the render mode to appear so incorrectly.
