How did you fix the Ai Mesh?
OK, this is a view of the AI mesh.
Note that I had to widen (elevate) the terrain at the bottom of the ladders, and add some "turf" texture on it. I also deleted the Faces on the cliff, because they're useless, even dangerous (the AI might think it's a good idea to climb the cliff). Stupid AI.
Secret is try (in CHEAT!:Town Walls), test (in CHEAT!:Besiege Castle), and then again and again...
Till the AI does what you want it to do.
Anyway, now I've finsihed the Swadians Castle, added ladders and/or small decorative siege camps, and I'm currently working on the Cities. Stay tuned fo updates next week!
Inshallah.
Reindi CastleRindyar Castle is a bit... difficult. Sometimes, the Attacker's Army won't use the 2nd ladder, sometimes it will. Don't know why, exactly. Tried everything. The reinforcement wave will do exactly the contrary, though. It won't take the 1st ladder.
Derchios CastleKelredan CastleRyibelet CastleTevarin CastleSenuzgda CastleHaringoth CastleVyincourd Castle already had 2 ladders.
Tilbaut Castle is quite unmodificable, due to its architecture and steep terrain.
