Insufficient data - supply a blend file
You have Cycles material nodes set as materials for the rocks. Cycles and Blender render material setups aren’t compatible.
Cycles’ and Blender Internal’s materials are not compatible.
In your case Blender is set to use the Blender Internal renderer, but the rock face object uses Cycles material nodes…
EDIT
Ah, too slow!
How do I make cycles compatible? Compositing isn’t my forte.
Wait, I got it. brain fart. Thanks for the help.
