Hello,

First of all, the structures in your mod are incredible !

I try to understand the way structure are generated in the biomes (using Biomes o' plenty)
I used this setup:

[structures.castle]
#Generate Castles?
generate = true
#Castle Spawn Chance [default: 0.5]
#Range: 0.0 ~ 1.0
spawn_chance = 1.0
#Castle Distance (in chunks) [default: 40]
#Range: 1 ~ 500
distance = 40
#Castle Minimum Separation (in chunks) [default: 8]
#Range: 1 ~ 500
separation = 8
#Biome Types the Castle can generate in
biome_categories = ["PLAINS", "FOREST", "TAIGA"]
#Biomes the Castle can NOT generate in
biome_blacklist = []

My understanding is each biomes with category Plains, Forest or Taiga will spawn a castle because of the spawn_chance = 1.
For what I see, it isn't the case at all (closest Castle 7000 blocks away).

The delta of the flatness is 4

Plains like the golden prairy doesn't have a castle by example.

What am I missing to try to increase the spawn rate of Valhesia structures through the world ?

Thanks for your time

Hi, thanks! Regarding your problem, I invite you to try our latest version (1.16.5-0.1.0), the config file has been improved. Some structures are still a bit rare with Biomes O' Plenty but we are working on it. If you want to make the castle a little less rare you can lower the "spacing" and increase the "spawn_chance".
