See attached.
These are two different backgrounds that are part of my front end. I created them in the same way (Game Object | 2D Object | tk2d | sprite), but about a month apart. Has there been an update in versions of 2dtoolkit that I've forgotten about?
The first background, as seen in nomat.png, I created 3 months ago. It does not have a material attached in the inspector. It renders nice and quick on mobile.
The second background, as seen in mat.png, I created about 6 weeks ago. It has a material attached in the inspector as you can see. It renders like a dog on mobile.
I've tried dicing them, not dicing them, removing the material (it just doesn't render then, even though not having a material on the first background does still render - so odd).
Any ideas?
