I am currently using both Gen4 and Genesis.

My computer is a first gen Intel MacPro and I'm running Snow Leopard since I can't buy Mountain Lion (although it works on 1st Gen-Apple decided it wants me to buy a new computer).It is a 4 core Xeon 2.66 Ghz so it works fine for most of my purposes.

DSON works- other than persistent poke through issues. Those have to be solved with the Morph brush-or post work.

I have lots of morph packages loaded in Genesis- when I transfer active morphs to the Elf Dress it takes 5 minutes the first time-as it projects the entire list. I suppose there is no way to make it ignore projecting foot morphs on the hair-although that would save time!

 The poke though gets worse when I re-apply "transfer active morphs"- although it only take seconds the second time around.

Unlike SOME people :-) -I rarely render MALE figures- but when I do-some of them are bearded- and Mec4D's beards (fiber mesh) move along with the face with Genesis. There are NO (to my knowledge) realistic beards for the Gen 4 figures.
