you can isolate figures and such by hiding everything and rendering one element at a time but then you have to play with reconstructing shadows and such. or using the alpha for that element, to isolate it in a master image. there is a new tool for Studio though which is designed to create masks of all your surfaces specifically for the purpose of isolating parts in Photoshop. http://www.daz3d.com/i.x/shop/itemdetails/-/?item=5636&cat=5
