hey there Zev0,  if the parent figure is what you refer as the controller then i did,since selecting the parent figure is needed in order to save the conforming item as wearable asset. sadly  when i load back the asset, the custom ERC is not there any more.

posted my question earlier in daz, just want to post it here for more replies and possible solutions.
