from low poly to higher poly do you just convert it to a subdiv? or is there something im missing? and i've noticed nurbs can't me unwrapped that way cause they dont really have UV's right?
are you gonna rig it eventually?
I don't know whether I would convert something from low to high poly, Id probably just plan the model to be high poly from the beginning.
As for Nurbs, Im not really sure about those, I only ever model with Editable Polys :S
Sorry I cant be much help
I did end up rigging the character to put him in his "beauty Shot", Ill put it up here tomorrow if I remember.
PS. The Colours on the wall decoration on my last post up there ^ look horrible on the monitor Im using right now, I hope its not what everyone is seeing.
