It's just textures displayed in the viewport ('6' button), plus in the lighting tab of the viewport I have 'use all lights' checked.
I never went into the lighting tab until I did a lighting course, but now I use it all the time. You can switch of all the lights in the scene, and just use the default, or you can just have one on at a time (handy when placing lights), or, as in the playblast, all lights.
P.s Bullet. Sorry man, havnt checked the last attachment you sent, am about to do so now....!
