Here's 3 simple furrowed brow morphs made in Zbrush for Antonia. 1 level of subdivision. They're not very large and all basically the same, subtle differences. If you want to use them, cool. I could do them over larger or change them if you wanted but not tonight. Actually not my finest work but I'm tired and navigating in Zbrush is like being wasted drunk compared to Mudbox or Blender.

One other thing. Sometimes you need to save your Poser scene and reload it for the subD morphs to successfully write to an injection. Something to be aware of...

The morphs appear in the body, in the morph parm group. There's no limits. The pmd that the pz2 calls on should stay with the pose. You can put the pz2 anywhere as I edited the file path absolute. It's just 3 files in the zip, not in a Runtime structure. The pz2, pmd, and thumb.
