Are there any general rules of thumb for how many UV maps an object should have, or how large the maps should be?
For Instance I am in the process of creating the LP of this p90. Should the whole gun be unwrapped such that it only takes up one UV space, and thus one map?
In an Eat3D DVD entitled "the fountain" the author creates 3 separate UV maps for the whole fountain piece. He does one for the base, middle, and top of the object. I am unclear on what circumstances warrant this, obviously it would have to be a pretty important set piece to warrant 3 UV maps, but other than that the details are unclear.
Also not sure if the phrase im using "UV maps" is correct. Also how I know this is dependent on many variables, but are there any general rules of thumb for what the texture budgets for objects should be. e.g. A medium prop might get 512x512, a big prop might get 2048x2048 etc.
