The main question I have is how to deal with subdivisions on a Low poly model where I use alot of tris(as opposed to quads). When I subdivide it, it can get pretty hairy in spots and I usually find myself doing alot of painstaking vert welding in trouble areas. (or just fixing up the normal maps in photoshop)
Do you make a copy of your low poly and totally work it over into quads and then subdivide it? Do you just take the hit on your tricount and keep the lowpoly in quads?
Any advice or tutorial links on improving efficiency here would be awesome
