Blender 3DT Train & Rail Generator Documentation

Blender Rail & Train Geometry Node: draw a curve and get tracks, sleepers, ballast and banked turns in seconds. Includes junctions, train instancing, and clear controls. Ideal for games and cinematics.

Getting started

• Open the included Blender file in a clean test scene and inspect the Geometry Nodes modifier or node group before changing values.
• Save a working copy, then test the main controls on a simple object so you understand the scale and performance cost.
• Use the product with Blender where those tools are listed on the product page.

Best workflow

Work in small iterations: adjust one control at a time, check the viewport result, then duplicate the setup for your own scene. This keeps procedural changes predictable and easy to art direct.

Compatibility and support

Use the Blender version and requirements shown on the product page. For help, use the product FAQ or contact 3D Tudor through the creator support route shown on Superhive.
