UV mapper should work just fine in RD3D. And, yep, there won't be any posability. A work-around for mapping would be to render your figs in Poser from the six ordinal directions. Then use these renderings to construct a six sided map in Photoshop or whatever and apply it to the object using the box/face>full box mapping mode. I think that type of mapping is covered in the RD3D manual, though I can't remember for sure.
