Certain Meshes not Rendering (Invisible)

[Yotingo]

Hi,

I just recently purchased Obi Softbody and have been trying to integrate it into my project. I was able to follow the Youtube tutorial just fine and everything worked with a standard sphere. 

Now I'm trying to use a skinned mesh but nothing is being rendered when I assign the 'Mesh' onto the 'Skinned Mesh Renderer' component.

I have done the following:
 - Enabled Read/Write on the mesh
 - Copying the 'Skinned Mesh Renderer' component from another to ensure the 'Bounds' are correct
 - Adding the Obi components to a pre-existing (working) mesh after deleting the associated armature. | This rendered at first (as broken disjointed triangles) but disappeared after running.
 - Smashed face on keyboard

The fourth attempt was the most satisfying but nearly resulted in a fatal error.
Any help would be appreciated!
