Miss Nancy- Thanks for the suggestions. I tried your idea of unchecking the option for "Use Irradiance Caching" and the image is still rendering! I'll have to see how long it takes and then try your other ideas.

3D-Mobster- Sorry, but I have no idea what you're talking about.

The mesh has already been optimized for use in Poser: all the facets face the correct direction, the vertices have been split in UV Mapper, and I never use Poser's "Smooth Polygons" option.

Modus0- Thanks for the link. I'll read through those ideas. :)
