I would like to upgrade some CC jewelry to be only available at a selected BV destination. I would also like others to be 'findable' by searching at the beach.
I can upgrade accessories to BV in general using the Wardrobe Wrangler, and it has options for these special upgrades as well, but these have never worked for me (and the DJS forum is no more).
I guess I would have to change things in SimPE, and I'd be grateful for any tips.

I tried searching the tutorials and forums here with the same question in mind, but didn't come up with much. (anyone? any MTS2 threads on this?) I did find some at MATY though.

MATY BV jewelry tutorial threads
Converting Pre-BV Accessories to fit in new BV Accessory Section
Upgraded Jewelry for the BV Machine

Thanks for pointing me to these threads. The first one actually has a short tutorial on the first page on how to do this all in SimPE. It worked fine, with the exception that an earring which was set as collectible might have replaced the shell earring and/or the shell necklace.
