Sandustry launches into Early Access on August 13, 2026, and the developer has already confirmed that the game is built with modding in mind from day one. A Sandustry new buildings mod lets you add custom machines, tweak production chains, and reshape entire maps, which matters because the base game only ships with a fixed set of structures. Get ready to turn the vanilla experience into something that fits your playstyle, whether you want faster drills, smarter logistics, or entirely new factory layouts.
Why Build a Sandustry New Buildings Mod
The official Sandustry website states that the game supports custom maps, new buildings, processes, and full overhauls, with dedicated modding tools shipped alongside the game. That means you are not fighting the engine when you start creating content, because the developers designed the architecture to accept player-made additions from the very first build. The modding tools are not an afterthought, and the community has already started experimenting with them in the official Discord server. When you create a Sandustry new buildings mod, you gain control over several core systems that directly affect how you play:
-
Production chain balance — adjust output rates, input requirements, and energy costs for any machine
-
Building placement rules — change footprint sizes, adjacency bonuses, and conveyor compatibility
-
Custom machine behaviors — script unique logic that the vanilla buildings do not offer
-
Map generation parameters — control ore distribution, cave density, and biome variety
-
Visual identity — give your buildings distinct textures and animations that fit your theme
The real payoff comes from combining these systems into a cohesive experience, because a single building tweak rarely transforms the game on its own. Players who report the most satisfying results typically pair new machines with custom maps that are designed around those machines, which creates a feedback loop between world generation and factory design. If you want to understand the full pipeline before you start, the mod installation guide walks through the folder structure and file requirements in detail.
Core Systems You Can Modify
Understanding what the modding tools actually expose is the first step toward building something meaningful, and the official documentation covers three main pillars: buildings, processes, and maps. Each pillar has its own set of parameters that you can tweak, and the best Sandustry new buildings mod projects touch at least two of them to create a coherent experience.
Building Parameters and Machine Logic
Every building in Sandustry is defined by a set of JSON files that control its behavior, and the modding tools let you create new entries from scratch or override existing ones. The most important fields include processing speed, input and output slots, power consumption, and visual scale, but advanced mods can also define custom logic through the scripting API.
| Parameter | Vanilla Range | Modded Potential | Impact on Gameplay |
|---|---|---|---|
| Processing speed | 0.5x – 2.0x | 0.1x – 10.0x | Directly affects production throughput |
| Input slots | 1 – 3 | 1 – 8 | Enables complex multi-ingredient recipes |
| Output slots | 1 – 2 | 1 – 6 | Allows byproducts and parallel outputs |
| Power consumption | 5 – 50 units | 0 – 200 units | Changes energy grid requirements |
| Building footprint | 1×1 to 3×3 | 1×1 to 5×5 | Alters factory layout planning |
The scripting API is where the Sandustry new buildings mod really shines, because it lets you define conditional behaviors that vanilla machines cannot express. For example, you could create a drill that speeds up when it detects a specific ore type nearby, or a smelter that produces different alloys depending on the time of day. Community reports suggest that the most popular custom machines are those that solve a specific logistical pain point, rather than simply boosting numbers.
Map Generation and World Layout
Sandustry map mods control how the world generates, and the parameters here are just as important as the building stats. The official tools expose seed values, ore distribution curves, cave density, and even the placement of ancient civilization ruins that hold valuable secrets.
| Map Parameter | Default Value | Modded Range | What It Changes |
|---|---|---|---|
| Ore density | 1.0 | 0.2 – 3.0 | How much raw material you find per chunk |
| Cave frequency | 0.4 | 0.0 – 1.0 | How often underground passages appear |
| Vault count | 3 | 0 – 10 | Number of ancient ruins to discover |
| Surface height variance | 0.3 | 0.0 – 1.0 | How mountainous or flat the terrain is |
| Resource tier spread | 1.0 | 0.5 – 2.0 | How quickly higher-tier ores appear |
Players who pair a Sandustry new buildings mod with custom map generation often report that the combination feels like a completely different game, because the world now contains the exact resources your custom machines need. If you want to understand how vanilla world generation works before you modify it, the cave exploration guide explains the default vault and ore distribution mechanics in detail.
Building a Complete Mod Setup
A complete Sandustry mod setup rarely consists of a single file, because the most satisfying experiences come from layering multiple mods that complement each other. The official Discord server hosts a growing collection of community mods, and the developer actively shares modding tools and examples there. The key is to plan your setup before you start downloading or creating content, because conflicting mods can cause crashes or silent balance issues.
Combining Gameplay and QoL Mods
Sandustry gameplay mods change the core rules, while Sandustry quality of life mods remove friction without altering the fundamental experience. The best setups include both, because gameplay mods often introduce complexity that quality of life mods then manage.
-
Gameplay mods — new machines, altered recipes, harder or easier resource curves, custom victory conditions
-
Quality of life mods — faster conveyor speeds, larger inventory stacks, clearer building previews, automated sorting
-
Map mods — custom world seeds, tailored ore distributions, hand-crafted cave networks, themed biomes
The trick is to test each mod in isolation before combining them, because two mods that both modify the same JSON file will conflict. Community reports indicate that the most stable setups use a single gameplay mod as the foundation, then add quality of life mods that do not touch the same files. The visual mods guide covers how to handle texture and asset conflicts if you want to customize the look of your custom buildings as well.
Step-by-Step Mod Creation Workflow
Creating your first Sandustry new buildings mod follows a predictable workflow, and the dedicated modding tools make the process more approachable than you might expect. Here is the sequence that most community creators recommend:
-
Set up your workspace — create a mod folder in the game directory and copy the example files from the modding tools
-
Define your building — write the JSON file that specifies stats, slots, and visual properties
-
Test the building — launch the game with your mod enabled and verify that the building appears in the build menu
-
Add custom logic — use the scripting API to implement any unique behaviors your machine needs
-
Balance the numbers — run test factories to ensure your building fits the intended progression curve
-
Package and share — compress your mod folder and share it on the Discord server or Steam Workshop once that becomes available
The modding tools that ship with the game include a validator that checks your JSON files for common errors, which saves you from the trial-and-error debugging that plagued early modding scenes in other games. If you want a deeper dive into the technical side, the modding tutorial covers the scripting API and advanced file structures in detail.
Balancing Your Custom Machines
Balance is the hardest part of any Sandustry new buildings mod, because a machine that is too powerful trivializes the game, while one that is too weak gets ignored entirely. The community has developed several heuristics for evaluating custom buildings, and the most useful approach is to compare your machine against the vanilla equivalent that occupies the same production niche.
| Vanilla Building | Production Rate | Power Cost | Your Custom Building Should |
|---|---|---|---|
| Basic Drill | 1 ore / 2s | 10 units | Match or slightly exceed this rate |
| Furnace | 1 ingot / 4s | 15 units | Offer a trade-off, not a strict upgrade |
| Assembler | 1 part / 6s | 25 units | Require more inputs for faster output |
| Conveyor | 5 items / s | 5 units | Move items faster but consume more power |
The golden rule that experienced modders follow is that a custom building should solve a problem the vanilla game does not address, rather than simply being a better version of an existing machine. For example, a drill that mines in a 3×3 area instead of a single tile is interesting because it changes your mining strategy, not because it just mines faster. The factory buildings guide explains the vanilla machine balance in detail, which gives you a solid reference point for your own creations.
Frequently Asked Questions
What files do I need to create a Sandustry new buildings mod?
You need a JSON file that defines the building's stats and properties, plus optional script files for custom logic and texture files for the visual appearance. The modding tools that ship with the game include example files that show the correct structure, and the validator checks your work before you test it in-game.
Can I combine Sandustry map mods with custom buildings?
Yes, and this combination often produces the best results because you can design a world that specifically supports your custom machines. Map mods control ore distribution, cave density, and vault placement, so you can ensure your new buildings have the resources they need. Just verify that both mods do not modify the same files.
Do Sandustry quality of life mods affect game balance?
Quality of life mods are designed to remove friction without changing the core balance, so they typically do not affect production rates or resource costs. Faster conveyors and larger inventory stacks make the game more comfortable to play, but they do not give you an economic advantage over vanilla players.
Where can I share my Sandustry mod setup with other players?
The official Sandustry Discord server is the primary hub for community mods, and the developer actively shares modding tools and examples there. You can also check the Steam announcements for news about Workshop support, which may arrive after the Early Access launch on August 13, 2026.
How do I fix conflicts between multiple Sandustry gameplay mods?
Start by isolating mods: load only your new buildings mod, then add others one by one. Use the validator to catch duplicate building IDs early. If conflicts persist, check shared JSON files for overlapping machine definitions—rename unique IDs to resolve clashes.
