UMM maybe i'm missing the point here but why don't u just layout the subdiv surfaces UV's and texture them? why do u need to convert them back to polys?. and if u are going to convert to polys texture it and then convert back to subdiv's then it doesn't matter if u lose a little detail on the poly model because u r not going to lose detail on the texture when u convert back to subdivs um if i'm talkin a loada rubbish then tell me
