Hi,
I've also posted this question on Zbrush Central and one or two other forums and thought I'd give it a try here.
I'm trying to re-pose a model using ZSphere rigging (I'm using ZBrush 4R2b). I've followed this tutorial:
http://www.pixologic.com/blog/2010/12/zbrush-4-part-1-zbrush-rigging-with-a-single-subtool/ as well as this info here:
http://www.pixologic.com/docs/index.php/ZSphere_Rigging
All has gone well with the rigging and posing parts, until I try and preview the high rez sculpted mesh on the pose. When I press Shift and click on the Tool:Adaptive Skin:Preview button the model jumps back to it's original (sculpted) unposed mesh. However, when I click on the Tool:Adaptive Skin:Preview button (not holding Shift), it works (is posed) but unfortunately my high resolution sculpted detail is not displayed, just a smoothed version of my low resolution mesh.
Any ideas on what I'm missing? Seems like a few people have gotten stuck with it as well (according to the replies on that tutorial video page). Otherwise I might try and use Transpose Master. There's a tutorial that follows on from the original one. I can probably adapt it:

Thanks.
