Your second question

You should be able to import a PZ2 file into DAZ then save it as a scene.  I have tried it with a PZ3 file and DAZ4 Pro and it works, although the imported V3 figure was about 20% larger than the Genesis figure. It will be important to have the paths to the Poser directories set up correctly in DAZ. If not, you may have to locate meshes and textures manually, which will be a bit tedious.

Hope this helps
