Whew! Thanks a million TT! Had no idea that button was active unless sun/shadows was turned on. Didn't even think to try that.

I'll post this model to the forum once it's completed. I'd call it the Mother of all SU projects. 18 buildings and all the related parking lots, side walks, grounds, tress etc.

Really TT, thanks for the fix!
