I've got a very large model. I can see it fine in object view, but it keeps coming up blank when I try to render it. Here it is in 3D view (through the camera):
...and here it is after it's rendered:
Everything's enabled in outliner, and all of the layers are checked for rendering under Properties/Render Layers.
I feel like I'm missing something obvious, but I'm at a loss. Any suggestions?
