Thanks for the answer!
Dang, sad to hear that, I tried making the backgrounds very red (an example the Selphie model) - and it seemed like there were transparent bits around her hairline that actually went through her head - I'm not sure if this is just this one model or perhaps it was down to something else (I've never done 3D work) - but if I was to try and get transparent images of the models, is the PS way the optimal route?
Or is there perhaps other software than Noesis that would be better suited?
