3D Model Building Software

Most of the content of 3D Train Studio consists of 3D models that have been created in external 3D programs such as Blender, Autodesk 3ds Max or SketchUp. Every user of 3D Train Studio can add their own content to the program. The Studio does not limit the creation of models to a specific program, but supports all programs that can export models to the glTF-2.0 format or the X format.


Model creation for 3D Train Studio with the free program Blender, especially in version 2.8 or higher, is recommended.

Blender 2.8 and newer:

  • Supports the export to glTF without special addons.
  • For animated models, the frame rate in the Output tab must be set to 24.

Blender 2.79 and older

  • Download the adapted DirectX exporter and unzip it to “C: \ Program Files \ Blender Foundation \ Blender \ <Version> \ scripts \ addons”, overwriting the existing directory “io_scene_x”. The exporter contains a few modifications so that the DirectX models are fully compatible with 3D Train Studio. For more information see “_init_.py” in the archive.

Autodesk 3ds Max

Autodesk 3ds Max has had several name changes over the years:

  • 3D Studio, 1988-1994
  • 3D Studio MAX, 1996 – 1999
  • Discreet 3ds Max, 2000 – 2004
  • Autodesk 3ds Max, 2005 – 2022 and onwards

Autodesk 3ds Max costs £246/month. Discounts are available for longer contracts and for Educational sector users.


3D models can be created with the free Google SketchUp. Sketchup calculates and exports back surfaces by default. Back surfaces are usually unnecessary for 3D Train Studio and so they should be deactivated. SketchUp does not support animation.
