I think being able to bake in displacement might be interesting or useful in certain cases.  A displacement map can have much more detail, however, than is actually present in a model on the polygonal level.  Displacement baking would only be able to move the vertices which exist on the model.  Poser already seems to use much higher-resolution figures than most other apps, and the current implementation of displacement is one of the key ways to make a low-res model look like it has more detail.  Personally, I'd prefer to see Poser move toward tools which could improve handling of lower resolution geometries, starting with better rigging and some sort of subsurface smoothing.

Displacement is also limited to deforming a surface along its normals, so the types of baked deformations would be limited.

But being able to see the displacement in preview while posing could be useful.

I think displacement baking could probably be done via a Python script, right now.  (I'm not volunteering, though.  :lol:  Anything with UVs in the mix is too much of a headache for me.  )

And, edit: You can bake in displacement using UV Mapper Pro, too.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
