Hi folks , Iv'e modeled a left boot which has been converted from poly's to sub d's.I now want to mirror it so as to have a right boot using sud d surfaces>mirror geometry but I get an error message saying"select a subdivision surface whose geometry you want to mirror" even though the object is already selected. In an earlier file Iwas able to mirror a low poly boot but it attaches itself to the mirrored object even though 'merge with original is turned off in the options box. any suggestions? Cheers.
