Boni, I always use texture projection( that is one vilters is referencing to). I although use a program that is no longer available, though you can still get the demo here and there on the internet. It was once very popular and not so hard to do. You dont have to worry about seams at all. I thought i already explained that to you in another thread?

I made a very sloppy example for you. The nose is always a troublesome area due to the stretching of the pores. Projection painting corrects this by 90 %. On the left you see like 2D painting( photoshop etc) and on the right 3D projection painting. As you can see the pores are not stretched. Dont look too good lol cuz i didnt make it a great fit for both pictures.
