But you must remember that most of the third party render engine use their Own shader Language.
try telling poser users they have to Dump ALL of their many texture Sets for V-Chick and redo everything from scratch using Vray or mental ray shaders and watch the reaction.

Ah, this is the beauty part. Poser textures are incredibly simple, even if they're expressed in an awkward way (eg, transmaps have the unique property that no matter how many time you invert them, they're always wrong)

A Poser texture is rarely anything more than

1. transparency
2. texture
3. bump

Those three maps cover %99 of what I've ever bought from Rosity or Daz.  There is no complex BDRF, no emitters, very rare use of SSS . . . basically a Poser texture set converts easily, so long as it "plays nice" . Maybe there are a few folks doing exotic things with complex procedurals in the Materials tab, but that's very rare.

There is no renderer that has any trouble with a bump, a texture, and transmap, so long as they're output correctly-- which is what an API does, so with a decent API, there's no problem of texture conversion, in fact that's the whole point of the thing.
