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
