Any help will be appreciated since we have lots of uncovered information about topologies and other custom maps stuff.</note> Custom Maps in Rust allow us to make our own unique variant of the Rust world within the game boundaries. #Overview Full list of content available regarding custom maps for now: <page>Terrain</page> – what is terrain and how it works, splat types (splat/biome/alpha/topology) information. <page>Topology</page> – full list of topologies, tables and lots of other useful information how to work with it and make things on your map spawn properly. <page>Map Data</page> – detailed article for nerds about how .map files and SDK. <page>Map Data</page> – detailed article for nerds about how .map files and SDK work. #SDK All interactions with map data requires using [Rust.World SDK](https://github.com/Facepunch/Rust.World). It is a foundation for writing your own tools, allowing you to visualize, edit and save data within .map files. At this moment SDK allows you to modify this data: (to-do: change the list if it's not accurate? add actual links to articles about these things?) + <page>Terrain</page> (land/water height data) + Splat (textures, biome, alpha, topology data) + Prefabs (ID, position, rotation, scale) + Paths (rivers/roads: position, width, texture type for roads?) #Prefabs limitations <note>This should go to "Prefabs" article but I'll leave it here for now.</note> At this moment SDK has some limitations that you should keep in mind while working with your custom map. ##Networked entities cannot be rescaled All doors, IO entities, deployable objects (for example, <page>Work Bench Level 3</page> or <page>Bed</page>) cannot be rescaled and will remain at values `1, 1, 1` no matter what. ##Some building elements won't spawn with stability enabled on your server Almost all items from **Construction** category that you can insert into building blocks like <page>Reinforced Glass Window</page> or <page>Netting</page> won't spawn as long as you have building stability enabled on your server. Make sure to disable it if you want to use any of these prefabs. ##Deployable objects will decay Furnaces, wooden signs, and many other prefabs (usually they have "Deployed" in their name) will decay. If you want to use them as a decoration for your maps but don't want them to disappear, you have to disable decay on your server. #Hosting Custom Maps See <page>Hosting a custom map</page>.
