There is plenty of information on how to do it, it just has to be found. Starting from the ground up wont be easy though but its possible. I feel like im mostly over the technical hill and it took me around 9 months.
basically the programs I used are 3ds max, zbrush, xnormal, and NDO2, Photoshop, marmoset. As for the youtube, never realy put too much thought into it. I might do it when I get better, to expose my work more.
