Would you recommend this for anything? What if the size specs were a 512? Would baking at 2048 and knocking it down 75% to 512 be good or would most of the details become too obscured?
rendering out larger isnt something i do all the time, but it can help if you have really fine details that arent showing up quite right, or are getting poorly anti-aliased. Not sure what you mean about 75% ? A 512x512 is actually 1/16th the size of a 2048x2048.
