I just bought a [GUI]Splatter in the shop and it doesn't work. How do I make it work? I activated it and I see an edit button by it. Thanks in advance.

Splatter is just like a texture u can edit..

Splatter is a texture used to modify the main menu's appearance. The picture is a like a texture : jpg format etc...
Don't you have a template?

Ok, I understand how the Splatter works now, and I don't think you need a template.
