Make a new SDK for players to add items to their inventory.
People that split world drop items from their avatar and have them in their inventory instead would lower vram usuage for avatars. Especially If the world drop item isnt activly in use.
Would be a possible way to expand the market place for vrchat in the future.
Having these items work like and be treated like avatars would be best, Limit what can be uploaded (poly count and vram size ect).
Maybe having custom uploaded items only show up for friends with default safty settings migth be best to.
