How to Access R6 Avatar Mesh Vertices?

I want to get the position of a random vertex from a 3D mesh used in a standard Roblox R6 avatar (e.g., the head, torso, etc.) so I can use it for gameplay logic or visual effects.

When I try to load the mesh using AssetService:CreateEditableMeshAsync(MeshId), I get this error:

AssetService::CreateEditableMeshAsync failed because no permission to load asset

This happens because built-in R6 avatar assets (and R6 bundles) are protected and cannot be accessed via CreateEditableMeshAsync due to permission restrictions.

Additional details:
Here’s the relevant code snippet:

local AssetService = game:GetService("AssetService")

local EditableMesh = AssetService:CreateEditableMeshAsync(MeshId) -- error occurs here

local Vertices = EditableMesh:GetVertices()

local RandomVertex = Vertices[math.random(1, #Vertices)]

local RandomVertexPosition = EditableMesh:GetPosition(RandomVertex)

Note: I don’t actually need to edit the mesh—just read its geometry (vertices and their positions). Is there a workaround to bypass the permission restriction, or another way to obtain this vertex data?

Unfortunately, due to strict restrictions, you have to be the mesh owner in order for the editable mesh api to work. You can just export and reupload the mesh under your own name as a workaround, but I personally think it’s quite a pain.

Are there any other approaches I could try?

You could store the vertex data as positions in a table if you only need to read the geometry for visual purposes. But yeah, there’s no way to use editable meshes unless you own the mesh, and if you did try to store all the vertices you’d still have to find a way to get the vertices without editable meshes.
