I've never seen anything like this before with PoseRay output. (I very 
much presume you're using PoseRay for generating the POV-Ray mesh2 
objects yourself, right?)

Theoretically it should be possible to merge into a mesh2 with multiple 
textures without loss.

That's a known problem, and difficult to fix without some significant 
internal changes to surface normal handling. At present, subdividing is 
indeed the only known workaround.
