Create: Train Parts — Changelog

Major Features

Added Multi-Size Bellows

• Added a new Bellow block for connecting train carriages.
• Added five different sizes:
  • 1×2
  • 2×2
  • 2×3
  • 3×2
  • 3×3
• Bellows now dynamically adapt their geometry and rendering to their size.
• Added custom models and item sprites for all sizes.
• Added crafting recipes using Create Belt Connectors.

Added Bellow Physics & Collision

• Added collision support for bellows on moving train contraptions.
• Bellows now have collision geometry that follows their curved shape.
• Added oriented collision boxes for more accurate frame collisions.
• Improved collision detection to prevent jitter when standing underneath bellows.
• Improved bellow alignment between connected carriages.

Added Bellow Ponder Scenes

• Added a new Ponder scene explaining how to connect bellows.
• Added animated bellow connections to the Ponder scene.
• Improved the presentation and animation of the connection process.

Improvements

Bellows

• Completely reworked bellow rendering and geometry.
• Improved the appearance of bellow frames and cable connections.
• Added dedicated frame end models.
• Improved curved segment positioning to prevent visual gaps and Z-fighting.
• Improved rendering on moving contraptions.
• Fixed bellow placement and sizing behaviour.
• Improved item model scaling for different bellow sizes.
• Added a placement arrow to help with positioning.
• Improved model textures and rendering.

Level Crossings

• Improved crossing barrier collision behaviour.
• Fixed collision shapes when barriers are disabled or closed.
• Improved barrier mode handling.
• Barrier mode changes now propagate correctly to connected arm blocks, including those on contraptions.
• Improved crossing bell collision behaviour.

Model & Rendering Optimizations

• Reduced the number of generated model files by combining multiple model variants.
• Added runtime model variant handling and caching.
• Removed unnecessary duplicate model elements.
• Improved generated model resource handling.

Bug Fixes
