Thanks basicwiz, I do have the morph brush and tried to use it, and I can see how with this tutorial it would work if M4 grabs V4, but what about if V4 grabs herself?... It wouldn't work at that stage of your tutorial where you say "Select M4 as the target and V4's arm as the item to tighten" because you can't choose the same figure for target and object to tighten... I guess the way around it would be, as suggested by Keppel to load a second exact figure of V4, but I was wondering if there was an easier way around it?

Thanks everyone for the many suggestions, I'll try and dig deeper, so to speak...

A picture being worth a thousand words, I basically want this effect (can't put the whole pic, it's not mine...)

Hmm, sorry I did have a look at that link and it talks about magnets but I failed to see how this would help me with my specific issue? I understand I could use magnets to deform the skin of the breasts, but I can do that with the morphing tool already. My issue is that is I can't, in the morphing tool, select V4 breast, and then say that I want to "tighten the fit" with the goal being V4's hand (or vice-versa, doesn't really matter), because "V4 hand" is part of the same figure as "V4 breast" so it won't let me select it. I'd like to know if there is a way around this in effect.

Thanks, I'll have a look!
