I would love to see this. It's one of the few things I miss from Second Life, where emotes, toys, and other things weren't tied to only one avatar, but to your account as a whole, allowing you to use them on any avatar.

Could potentially also reduce avatar sizes indirectly as well. Instead of hard baking some dances or whatnot into your avatar, you just "add" it to your inventory to use on all avatars, including ones you didn't upload.

This + emotes

It would be pretty good for performance in the long term since the avatars wouldn't need to have all the assets, audio files, textures, and materials pre downloaded to be seen. if you have an avatar that you like it has tons of toggles that you don't use, you are basically forcing everyone in the instance to download things that they wont even see.

so if you want to show a prop, you can just access it in your inventory and it would then be downloaded for the other people in the world, and your avatar would be lighter and more optimized for not having 20 preloaded props.

also if clutter is a concern, just restrict to summon one prop per person and then 3 or 5 for vrc+ users. the prop inventory can be like 50 for normal players and 500 for vrc+.

also crashers... just open the asset inspector (copy and paste the user inspector page) and you can block the prop, report it, send to a friend, favorite, see creator... if you have a prop that crashes you, just dont spawn it again and delete and report. in the avatar system if the avatar is crashing you, you need to go to the website and change it there, otherwhise you insta crash when you log in, and good luck doing that if you are on a steam account where you dont have access to the website ._.

TLDR: the prop system would make avatars lighter and more optimized, and give more options to the player to express themselves

Additional my thought about the feature for prop :

Separately from avatars, these are objects that users can upload and summon into the world.

Restrictions such as disallowing (or very strict restrictions on) general instances and allowing unlimited access only to specific roles in group instances should be implemented at the same time.

These features would allow particle performance without the need to co-create worlds, while still preventing insane avatar uploads that would have a huge impact on performance.

プロップ機能についての私の考えを追加：

アバターとは別途、ユーザーがアップロードしてワールドに呼び出せるオブジェクト。

また、一般的なインスタンスでは許可せず（もしくは非常に厳しい制限にする）、グループインスタンスの特定のロールにのみ無制限に許可する等の制限を同時に実装します。

こういった機能があれば、ワールドを共同製作せずともパーティクルパフォーマンスを行うことが出来るようになり、同時に、パフォーマンスに対して甚大な影響を及ぼす非常識なアバターのアップロードは抑止されたままになります。

I feel this would also be a great starting point for an eventual built in market.

I'm not too sure how selling avatars might work through vrchat, but props would be pretty straight forward

This would also save a lot on avatar performance, making it so props don't need to be added to every avatar upload and can be loaded only when they need to be spawned

Could also add it to the safety options to default that you can only see your friends props

this would be amazing. Personally, I think it'd be great to have friend requests handled as they are described in Ready Player One (the book); where its a custom 3d object that is basically a business card; like it has your username and bio, but also doubles as a friend request.

Just a thought: inventory items could have a different selection outline to be easily distinguishable. For example it being green, orange, dark blue or whatever instead of light blue.
