Loading a Roblox catalog item for EditableMesh

I want to mess around with some avatar items to achieve a neat effect which involves modifying mesh vertices, I was going to do this with my avatar but I was hit with an error because “I don’t have permission to load those assets”, is there any workaround to this? I could reupload the assets into my account I guess but I am not sure if that is allowed and I don’t know how to do it anyway.

Sorry for the slow response - unfortunately, this isn’t possible. Meshes from the avatar marketplace can’t be loaded into EditableMesh.
