It's definitely a geometry issue of some sort, though it could be caused by smoothing, displacement, bump, or texture filtering. Can you post a wireframe of ONLY on of the affected areas, or perhaps a chunk of the areas in a new, close up render? I'd like to see the specifics of it. in general, that ballooning would be caused by smooth polygons, but shutting them off for the whole scen may not be necessary -- select that object, go to the properties tab of the dials thingy, and uncheck smoothing for that item to check. hth, ynsaen
