uvw mapping, i really want to learn how to properly map. i’ve read many tutorials on uvw, and i understand the main concept of the little pieces pasted on a sculpture
, but on 3dmax i unwrap the uvw and when editting the uvw i flatten the object into several pieces. now i dont get home do i know which piece is which part of the object. on the tutorial it says that when u clicked on the piece on the uvw editor it got red on perspective mode, it doesnt happen in my 3dsmax. also i’ve seen when mapping faces it flattens up but it doesnt actually separate into different pieces, its more like a mask that its afterwards putten in the person’s face. Ive tried searching in google lots of times but i just cant get it right. please help
