before posting this thread I searched forum on this topic. they have been discussing Maya along with ZBrush/Mudbox workflow.
I would like to know, if it is possible to convert a high > low poly ONLY/within Maya?
NOTE : Unfortunately I already UV mapped and also textured the model.

eg: I have a Car as shown in screenshot (more than 2 million polys). I want to have a low poly model, coz rendering a single frame takes around 5 mins (without any render passes). So how can this be accomplished.
Sorry for noob question, I have ignored this topic before, but "learned" things quite lately.
