Some basic questions on how to generate terrain. I'm getting an error that "attempt to index local 'tp' (a nil value)".
I have Terrain preset: custom , with pattern set with string.

I'm using generation scripts like these to try (they boot back to main menu):
{"maze 4 (bifurcation)", "Maze4(8, 40)"}
Translate({"maze 4 (bifurcation)", "Maze4(4, 50)"}, -0, -0)
TP({"maze 4 (bifurcation)", "Maze4(8, 40)"},{"maze 4 (bifurcation)", "Maze4(8, 40)"})

Why do the patterns need a name? They're not used ingame as far as i can tell, makes config strings longer.

If i do something like...
TP( ...What do i put here???... , {"maze 4 (bifurcation)", "Maze4(8, 40)"} )
... i don't understand how to add default terrain generation script to just add grass/sand/mud the default world. Terrain needs to be normal, but water be maze4-like. It's just default maze4 has way too small gaps and i have trouble even seeing those tiny dots in map. Water canals need to be wider too.
