I'm noticing a significant difference between when my objects are observable in the 3D View and when the objects are rendered.
Both objects have a material with toon settings and each have materials (incorrectly?) added to the object. the human mesh has separate textures for the head and body. The sword and the human mesh both have mapping > coordinate set to UV and Mapping > Map set to UVMap, however only the head texture seems to show up properly, and the sword texture doesn't show up at all.
