Sadly without the use of mods, this can't be done in any way as Minecraft wouldn't "support" it. And even if it would be possible it would suck out all the player's ender chest as anyone can access any ender chest but still get their private inventory.
@BlackSpigot.comI am reaching you about support for the Unity/VrChat Section of BlackSpigot.com. Please open a conversation with me I will send my discord. I need more file space in order to upload models, witch is what people want.
