If the delta folders (the !DAZ folder that gets added to your library and similar) are put into the main P5 runtime, then INJ poses should work from any other runtime. I've never had any problem with it.

Most MAT poses work OK, except that you have to move the bump map from the Gradient Bump channel to the real Bump channel in the material room. The free Mat Pose Edit program (I'm sure someone can give a link) can batch convert MAT poses (even entire folders of them) so that you don't need to do this.

The only problems I've had with things not working at all are joint-controlled morphs that depend on crosstalk (have to adjust by hand) and some complex hair models that won't render (have to jump through hoops to fix those.)
