Avatar appears extremely small in the preview screen
available in future release
chiugame
Thank you for your continued work on the development and maintenance of VRChat.
Currently, there is an issue where the avatar appears extremely small in the avatar preview screen.
Because of this issue, the accessory position editing feature is practically unusable.
Specifically, the following situations occur:
- The avatar is so small that manipulating positions is practically impossible
- Please see the attached image for details on this situation
If possible, I would appreciate it if this behavior could be investigated.
Thank you very much.

Looking at the avatar ID avtr_c112abee-1d02-4655-8f91-d8a37a9f488c, I can see two issues going on.
The primary issue here is that the avatar uses a skinned mesh renderer which tracks to the world origin. I observed this from the "Nail_strap" object, but it's possible other objects did as well. As a result the further you would get away from the world origin the larger the calculated bounding box for the avatar became. This is something we are able to solve on our end and already have a fix for.
However even with the above fix your character still shows up about half height in the pedestal, this is due to objects on the avatar with a wide bounding box. Specifically the "Iwashi_HeadAcc" object I believe is the reason, it has a very large calculated bounds. That will need to be resolved on the setup of the avatar itself.

Kiro Thank you very much for your prompt response and detailed investigation.
The point that the size changes depending on the distance from the world origin completely matches the phenomenon we were experiencing, and it makes perfect sense.
I sincerely appreciate that you have already prepared a fix on the VRChat end.
Regarding the points that require correction on the avatar setup side (such as the bounding box issue with the Iwashi_HeadAcc), we will make the fixes on our end as you pointed out.
Thank you again for identifying the cause and for your detailed report.

Do you have a sample avatar ID?
What does the avatar look like in Avatar Details' 3D preview?

WubTheCaptain Thank you for looking into this.
Unfortunately, the avatars that reproduce this issue are all private, so I cannot provide a public sample avatar ID at this time. I am also unsure of the exact cause or what specific conditions trigger this behavior.
Regarding the Avatar Details' 3D preview, it looks exactly the same — the avatar appears extremely small there as well.
I have attached a screenshot of the Avatar Details preview for your reference.
Thank you for your help.

chiugame Developers can still access private avatar IDs.
This is a bug with the avatar that should be fixed in Unity Editor for the avatar imo, not with the accessories UI. Several reasons could cause it, for example mixing armature / FBX export scales (1 & 100 in Unity).
(Amendment 11:43 UTC: "Apply Transforms" in Blender FBX export several times will cause those too, IIRC.)

WubTheCaptain Thank you for the clarification regarding private avatar IDs.
Here is the avatar ID for your investigation:
avtr_c112abee-1d02-4655-8f91-d8a37a9f488c
I understand that the issue may be rooted in the avatar's configuration, such as scale mismatches.
However, I noticed that the avatar is displayed at the correct size in the newly added "Appearance" tab.
Since the VRChat client is clearly capable of rendering this avatar correctly in that specific menu, I believe it should be possible to achieve the same result in the preview and accessory editing screens.
I would appreciate it if the rendering logic used in the "Appearance" tab could be applied to these other screens as well to ensure consistent and usable behavior.
Thank you for your consideration.
