If you use 3DS Max then you should try the TextTools by Renderhjs…](http://www.renderhjs.net/textools/) script.
Its got everything under one roof, its donate-ware and it works in Max 2014 too.
UV-ing for textures and lightmap channels can be a pain when your starting out :mad:, but tools like this really help take the edge off of it IMO…:o
Good luck on your UV adventures…
