Quote - I've never used Scupltris but I have used Maya. When you select the head in Poser it will have a positive Y value. What I'm thinking is that somewhere, either in the export from Poser or the import into Sculptris or even when you're sending the model back to Poser from Sculptris the Y value is being altered. I can't remember exactly but I'll see if I can get the chance tonight to try out what I think is wrong and let you know.

yup set your dial to one. If your face touches the ground, then sculptris sets the Y-value for the imported mesh to zero. On import Poser will read zero.

I mostly altered the whole Body-mesh in sculptris and use it as a complete Body-morph. Check carefully what you are going to export. Just export the figure mesh - no attached hair or clothes nor any props, or your import won't work.
