mesh glitch with point lights

Graphics
1

I have some characters with a second mesh for their wigs (I know, bad to have two meshes for a character, but this model predates that realization). They look fine with ambient light, but with a point light–on some computers/graphic cards, like an Intel Mac Mini–there are visual artifacts where the body and wig meshes overlap. (On my MBP there are no such artifacts.) See screenshot.

Both body and wig have diffuse shaders applied. Might there be a setting that would fix it–any suggestions?

thx

I just saw a link to Aras’s blog entry about a similar issue, which will be fixed in 2.6: Unity Blog

So I checked my point lights and one was in fact set to “Auto,” and apparently was in pixel mode. Switching it to Force Vertex solved the problem. Whew!
