why? my answer to this question will make you laugh: i think this scaling thing could be an additional option to deal with shadow min bias. actually i am busy testing this idea with differing results. sometimes it seems to be easier to set the value right with a bigger universe, but i can't say for sure at the moment. might well be that i am wasting my time. accordingly, if you'd help me, you might well waste your time too:) success or failure, a script for that would be most welcome... ;)A.
