alot of the time when avis are ripped they are broken in some things like gogo or radial toggles does this fix it when uploading?

[LargestBoi]

@Rabidbean3713
The uploader tool doesn't "Rip" the avatar, it simply alters the existing avatar content and repacks it for upload. Long as the avatar is supported (SDK3 and unity 2019 or 2022) then it'll upload just fine. Its current ability to 'edit' the avatar ends at being able to bypass majority of password systems.

Will the upload function for Quest be added in the future? It would be very convenient, as some avatars can’t be properly taken and uploaded for Quest.

[LargestBoi]

@LordNesstor3
Unlikely at this point as the average user can't easily obtain corresponding quest VRCAs for uploading.

Wait so is this just hotswapping or am i stupid (dose it keep the original avatar id)

[LargestBoi]

@F15Fast
It's essentially a hot-swap without requiring unity, with the ability to remove/patch avatar passwords. It also is significantly safer then asset tools net based hotswappers/reuploaders due to some of the special sauce in UBZig.

The newly uploaded avatar doesn't contain ids linking to the original.

@LargestBoi would be cool if it was capable of making it a unity file ngl

[LargestBoi]

@Msiprism
Just use asset ripper or SARS or summin to get project ready files, this projects scope ends at going from VRCA to uploaded content.

[Msiprism]

@LargestBoi eh sars is ass assetripper aint bad just redo a whole avatar you have no clue how to even the menu was put together
