I would find this extremely helpful, emulating your modeling style is fairly simple with use of the wonderful papa viewer tools from the community, but understanding the conditions under which you bake your textures is both essential, and incredibly difficult with the resources obtainable at the moment. I understand what the textures do, but some posts on styling and a couple basic techniques for emulation would be wonderful.
