Current questions and answers regarding the map editor.

Oh, so you also need to storm castles? I'm having a hard time imagining how that can be done without a mod... Unless:
a) you create one unnecessary castle with empty walls, and leave the rest unchanged
b) when attacking it, you destroy the catapult with a combat script, and make its death model empty (destroyed – it disappears)
But I'm afraid it will turn out badly...

There is a special castle that doesn't have a city interface, but it doesn't need one, although you can probably only place a regular arena there :( The problem here is the catapult and some inaccessible wall tiles. I've heard somewhere that it's impossible to fix. And why without a mod? Let there be a mod, but so that we have all the siege arenas + all the other arenas replaced with just larger ones....
Maybe there are other ways to increase the arena size?
