Hi guys,
First post - sorry it's a stupid 'please help' post.
I'm just starting to use 2D Toolkit. I started using Unity 3D a couple of months ago, and am on the latest version of Unity 4.
When creating a Sprite Collection, I create the prefab, then go to the inspector, see all the lovely values and...
...no 'Open Editor' button appears anywhere. I've added the prefab to the scene, and otherwise done everything I can in the tutorial to start in my creation of a nice batch of sprites, but I seem to have stumbled at the first hurdle.
Any thoughts? Cheese? Chickens? Anything?
