So basically when you do this: https://www.roblox.com/avatar-thumbnail-3d/json?userId=1
It should give you a cdn towards where you can get some more hashes for different items
https://t0.rbxcdn.com/ce297d8c377fd3fff687bb816a7cc0ce,
we have determined that the first texture is always on t5 or t2 and the material, if there’s more than one texture t1, else t7
and the obj is either t0 or t2. Well most of the time it follows this pattern.
If any one knows more info, that would be appreciated
