Space Engineers 2 Alpha: VS 1.5 - Modding

Keen Support shared this announcement 2 months ago

Hello, Engineers!

With VS 1.5 update, we’re introducing the first phase of modding support for Space Engineers 2. This includes the release of the VRAGE3 Mod HUB (a tool for mod creation, management and publishing) and VRAGE3 Mod Editor (a tool for creating mod content). They are the same tools our designers and artists use to build Space Engineers 2. You are now able to create, modify, and preview content with ease directly in the VRAGE3 engine using a visual, game-integrated workflow.

  • First Phase: Data Modding Support
    • Skybox
    • Armor & Blocks
    • Character Model
    • Tools
    • Animations
    • Voxel Materials
    • Particles
    • Sounds & Music
  • VRAGE3 Mod HUB released; Tool for mod creation, management and publishing
    • Mod management and publishing right in the HUB
    • Steam Library > Tools
  • VRAGE3 Mod Editor released; Tool for creating mod content
    • Blender Support - Blender VRAGE Tools: https://github.com/KeenSoftwareHouse/Blender-VRAGE-Tools
    • Automatic Generation of Assets / Model files
    • Automatic Mount Points Generation
    • Built-in VRAGE3 Engine Block Preview
    • No Entity Type Restrictions
    • Proper Deformable Armor Blocks modding
    • Pre-generated Block Templates in the Editor
    • Dummies are now added in the Editor - not on the model itself
    • Dynamic Gizmo Transforms for Model Dummies - for example conveyor ports, etc.
    • Accessible Block Animations - such as infinite rotation and more
  • Improved ship roll motions
  • Added Unsubscribe Button to the Blueprint Screen
  • Added multiple sounds (Voxel Hand, Ship Drill, Toolbar selection, Magboots, Block not placed)
  • First-person is the default camera mode now
  • Character Animations additions and further polish

Example Mods: 

  • World sometimes fails to load with outdated mods
  • Modding: Scripting and code APIs are not included yet, but they’ll be released later as development progresses.
  • Color picker will be included in undo-redo for paint gun in a future update
  • After entering a cockpit for the first time after starting the game, the character may peek through the cockpit - this will be fixed in an upcoming update.
  • Keyboard and mouse controls are not customizable yet, but they will be!
  • Toolbar block groups and sizes (block selection via R key) are a temporary mechanism and will be redesigned in a near update.
  • We’re aware of incompatibility at launch of Space Engineers 2 on Intel Arc A-Series and Core Ultra Series 1 built-in Arc GPUs. We are working with Intel to enable the game experience and will provide relevant updates as development progresses.
  • We are solving ship movement edge cases (jittering in slow speeds or too many gyros present)
  • Performance
    • Performance optimization is ongoing. For Alpha release, we’re targeting 16x Red Ship grids at 60 FPS on recommended hardware.
    • Autosave may cause brief lags during gameplay.
    • Performance optimizations of ship collisions and destruction are ongoing, so it won’t be lag-free at this moment. We will be continuously improving it in the following updates.
    • PCU values per block may appear higher compared to Space Engineers 1, reflecting SE2's increased detail and more precise performance measurements. While the current total PCU limit is set at 400,000 in VS1, we plan to raise this threshold in future updates as we implement scheduled optimization improvements.
  • Space Engineers 2 Workshop: Displaying Steam Workshop Collections in-game is planned. We are working on better handling when Steam is offline.
  • The current GUI (Graphical User Interface) and HUD (Heads-Up Display) are works in progress. Our team is prioritizing core functionality first. Once we've confirmed all features are working as intended, we'll enhance the visual design and overall aesthetics.
  • Some blocks are decorative-only for now (for example, the Assembler is present but cannot produce components)
  • The inventory system will be implemented in a future update
  • Fracture models will receive additional visual updates in future versions.
  • The paint tool’s limited palette is temporary; future updates will include RGB/HSV color settings and custom palettes.
  • Work on enhanced sound effects is ongoing
  • The Alpha releases in English language, more localizations will follow
  • Tutorials will be added closer to the end of development.
