Hi Cimaira!

If you need some pointers regarding how to move things from DAZ Studio to Vue, check out my tutorial "DAZ Studio to VUE". You can find the link in  the tutorial section here at Renderiosity. It's a PDF file located at ShareCG.
I prefer to use .OBJ export in most cases and use Collada only if I need to pose the figure in Vue. The tutorial also explains how to improve the materials and how to avoid problems with missing textures.
