However when I run the SpriteAttacher script and it adds an item at runtime, that item is now getting a white background (in fact some of the background is even appearing yellow light the bottom right part), even though its an alpha image.
Do you know why my sprite is attaching with white space (instead of alpha)? The first image shows its whitespace, and the second shows the sprite settings (where it has alpha).

Turns out I'm a derp. Forgot I changed the shader!
loader = new SpriteAttachmentLoader(sprite, Shader.Find("Spine/Skeleton"));
loader = new SpriteAttachmentLoader(sprite, Shader.Find("Sprites/Default"));
