Mate I cant do any of it in my own eyes...but hey I give it a crack even if I know and complain I cant do it...gives dave something to do in his spare time too....

You will do fine.....I found when I texture in PS (havent done it in Maya yet) I have the UV map...get my colours from real images with the dropper...and spray/paint my own little colour pallete in the corner. That way you dont have to keep trying to get the colours matched...just a tip

cheers bullet
