i Cant edit the appearance of this mesh for some reason,please help me fix it
What are you trying to change specifically? you can change the material by selecting a material at the top of the property window… for this to appear on a mesh, you have to delete any TextureId that is there. You can also add a different appearance to the mesh by uploading a different MeshId.
You’re currently selecting a Model (see in the properties beside ClassName). Select the mesh inside the Model to view the mesh’s properties and change the appearance.
