Someone asked me a question do breedables work in opensim? Yes, breedables work in Opensim. I've successfully implemented them since 2016, and I confirmed their functionality again on Kitely in 2019. For instance, on April 16, 2019, Ricardo Sorciere stated:

"Breedable's do work i done that in opensim a long time ago."

This shows that breedables have been proven to work in Opensim for quite some time. I have somewhere all this scripts.
