How can I make an effect move along with the character?
Take a look at how it's done on the heroines of the "Haven" faction in the NHF project or in UVH

I think I've found an optimal solution, but you can also break down the donor model into parts and attach its parts to the recipient's skeleton with effects - at least, I've started creating a heroine for the "Sylvan" faction! :smile13:
