Is it better to have one or two large skins, or three or four smaller ones? Currently, I have modeled a house that uses 2 512x768 skins, and 2 256x384 skins...(yes, they are big. I plan on reducing them later on). Anyways, Would it be better, after reduced, to clump these skins together, and make one or two bigger skins, or keep them seperate, and use three or four smaller skins?

Thank you.
