It made for Femm but the concepts are the same. The hard part may be finding a good donor for Dusk. The donor's JCM need to be plain morphs. No dependencies need to be setup. It "can" work if the donor has dependencies setup but it takes more work.

If you get stuck in JCM and them not cross talking the way they should post back. I'll get that working for you. In the long run if you're going to work with Dusk more. The best way is to make a Dev rig. That way you only have to do it once.
