It might... if the meshes are not well-behaving, for instance if the 
normals of each mesh face are not /all/ consistently pointing outwards, 
or if the mesh is not 'closed'. Mesh objects (especially when generated 
by external programs and not POV-Ray) are notorious.

I would suggest to convert your meshes with Poseray to mesh2 objects 
which are much better behaving than mesh objects. I tried to upload your 
file as a whole into Poseray but it appears to be too big for the 
program, so upload chunks of meshes separately. I am not sure if you can 
put them together again afterwards as it is bad practice to edit mesh2 
files manually, but you can put them in a union at least.
