Description
Placemod adds new extraordinary very optimized and fast structure generator in the world. It spawns different structures based on schematics in the world on the server side. During the world exploration you can find various discoveries neatly generated from schematics. Produced structures can reach gigantic proportions, since schematics is not limited by size.
Any user can add arbitrary schematic to make it possible automatically appear in the world. Mod config provides the ability to adjust spawn rate. It is possible to generate villages constructed from schematic sets. I have collected more than 800+ great schematics and include them to standard mod releases.

Details
When Minecraft first time starts with this mod it may take a time is about 1 min, first reading any schematic entails appropriate calculating flags: permissible biomes, schematic air-skin to speed up and decorate spawn routine.

Even if your schematic have ground level (with grass, gravel, stone, dirt etc.) it will dig down as it is necessary.
if your scheme is made roughly mod will automatically detect air outside of your structure and place it goodly.
Villagers automatically spawns around towns and villages.
Every chest will have random loot according to its spawn method.

Schematics
You can find all *.schematics inside Placemod/Schematics/.
By default it has next subdirectories: Common, Floating, Underground, Underwater, Water, Village.
You can put your own folders and schematics inside without any problems.
* Common - conventional buildings
* Floating - hovering in the sky, like floating islands
* Underground - fully dug into the ground
* Underwater - appears under water
* Water - spawns exactly on water
* Village - same folder schematics tries to appear all at once

Mod Configuration
Spawn rate adjusting Config file located in config/placemod.cfg
[DENSITY = 0.01] Density is average amount of structures that can be spawned in one chunk
[RATIO_A = 1.0] Smoothing of saturation function
[RATIO_B = 0.5] Degree of saturation function
Saturation function f(x) = 2/(1+e^(-A*x^B))-1, where x - structure size deviation from average size. This function affects structure relative spawn chance.

Notice: Config file is very sensitive. There is no bad-numbers-protection, so put only reasonable values.

[STRICT_MODE = false] Flag 'false' allows to spawn floating structures additionally in common biome. May be only true or false.
[BALANCE_MODE=true] Replace rich blocks to poor
[FORCE_LIFT=0] Pull out structure from the ground and lift up (recommended 0)
[ROUGHNESS_FACTOR = 1.0] Multiplier of minimal acceptable roughness
[CHEST_LOOT_CHANCE=0.25] Chest loot chance [0..1]
[PREVENT_COMMAND_BLOCK=false] Prevent command block for spawning
[PREVENT_MOB_SPAWNERS=false] Prevent mob spawners to appear in the world

[ALLOW_ONLY_VANILLA_BLOCKS=true] Allows to paste only vanilla blocks

[MIN_CHEST_ITEMS= 2] Min number of stack per chest inclusive
[MAX_CHEST_ITEMS= 7] Max number of stacks per chest exclusive
[MAX_CHEST_STACK_SIZE= 3] Max item stack size for chest loot

[LOAD_OUTPUT=true] Outputs schematic-load messages to console

[ALLOWED_DIMENSIONS = -1, 0, 1] Structures is able to spawn only in those dimensions

Permissible biomes
Mod automatically classifies biome type as one of the: mesa, sand, snow, mushroom, water, nether, all others. Mod function checks biome pertinence to it class each time before structure spawning. It is fully compatible with Biomes O'Plenty, classical biomes and others gen-based mods.

Notice: When you add new schematics to the mod or create schematic-pack try to keep each schematic name with their author or publisher name in brackets (for example [Rock477]FloatingIsland, [Hiro24]Atlantis), and delete all special and whitespace symbols from name for convenience.

Notice: Do not create subfolders deeper inside Placemod/Schematics/ with names "Common", "Floating", "Underground", "Underwater", "Village", "Water", because it indicates spawn method and may to confuse you. That Folders already been created.

Requires: Forge

FAQ:

- Are you using any dependencies like schematica to spawn structures in the world?

- Placemod are fully independent. It can be easily added or removed.

- Where does the schematic folder go?

- %appdata%/.minecraft/Placemod/Schematics/Spawn style/Your folder/Your schematics

- For using own Schematics, do we also need the .flags and .structure files, or those are generated by the mod itself.

- You need only schematics. Nothing more. You don't need to touch *.flag and *.structure files, they will be generated automatically.

- How to make structures way more rare.

- Go to config and open placemod.cfg file then put density, for instance 10 times less than before (0.005 to 0.0005)

I hope you enjoy!
