Quote - I'm attempting to learn how to make DAZ n Poser meshes.

I get Poser don't like displacment maps.

Why don't Poser meshes use normal maps ?

Huh?  Poser does displacement faster than most other software, so why bother with normal maps when you have a software that can do displacement so well?  Normal maps aren't as good as displacement visually, and they're a pain to deal with.

No matter what it is, displacement maps, normal maps, or whatever... they always lose detail of the original geometry to some degree.  The ability to use high definition geometry is a much better solution.
