Custom Mesh for Image?

So the image component generates a mesh based on the ImageType. However this mesh is always a rectangle, which might not make sense for all configurations. Does anyone have some good pointers on how to extend Image to add more ImageTypes, which generate different mesh-forms (circular for example, or using the SpriteRenderer algorithm to generate a mesh fitting the image)…

Nobody has any ideas?

As the functions that generate the mesh are internal to the Unity engine, doubt there’s much we can do, apart from altering the mesh post output.
Possibly raise it as a feature request through the tool maybe?
