I will definitely save before trying to render to new window with the ultra global lighting of 75 lights. I will lock hair props before posing. I will uncheck IK before applying a ready-made pose (most of the time they give twisted effects if IK is on) If I spend an eternity getting an expression right I'll save it so I won't need to do that again. Ah, what's the use, been saying all this to myself for the past 4 years, you'd think I would have learnt by now :))
