The eyeball bit goes back to at least Poser 4.  Usually you use ctrl+mouse click to select the outermost layer of the eyeball, and use the Bryce top left glass mat (default), and all the other layers should shine through.

As for dynamic clothing, I'm not sure about later versions, but Version 5 didn't play well with it, though the object versions would sometimes 'come over'.

There's a program (or was) in Freestuff called 'grouper', that would tie all your textures together for export from Poser to Bryce.

I wish I'd said that.. The Staircase Wit
