Imagine if you could chose a range to rotate objects to create a nice looking scatter that's quick and easy to place.
example: I want to rotate between the ranges of 90 degrees and 100 degrees to make the chairs with a table look like they've been used and some people haven't pushed their seats back in.
this will help place junk. Other ideas on how this helps is with placing junk on a shelf to face the right direction but deviate slightly to indicate use.
I do this all the time but manually. it chews up time sometimes having to correct every individual placement to be slightly off, and making sure not to repeat placements for realisms sake.
