ok, here comes a more precise description of my problem.

first of I create a new UVset. having it active I bake texture. one problem is - within color mode there is no option to bake diffuse color only which I need. 2nd prob is the camera. I can bake from top/side/front/camera which doesn´t bake the texture to all faces but only those who are visible in viewport.. this is a heck! how do I bake all faces at once? and how do I bake diffuse color only?
