how do I use it in generated maps?
I know how it works in themes, but it does not show on the map I made. If I run it as a theme it works.
Not possible yet (as it would essentially double the memory required for the map alone etc.) but this might be possible in future versions.
Ah, ok. I have a pretty cool LandBackTex on my theme, it just wasn't picking it up on my Map that was pointing to that theme for it's info.
