Whenever I or someone else equips a UGC Bundle created by someone who isn’t Roblox and plays an R6 game that does not override the player’s avatar, the avatar body defaults to the 1.0/blocky variant and not an R6 version of the UGC bundle.
Here is a picture of my equipped avatar body parts - it is utilising the custom S15 avatar bundle, a UGC bundle evolved, skinned version of the original Robloxian 2.0.
And this is what happened when I joined an R6 Roblox game. My avatar’s body defaults to the 1.0 body.
Expected behavior
The expected behaviour I would want would be a UGC bundle that acts like a Roblox-created bundle - that being, when I enter an R6 game, my body turns into an R6 variant of its R15 variant. This would provide consistency across all Roblox experiences and would not discourage the use of UGC bundles by many talented UGC creators.
