Modeller is a part of the LFS Editor. It is used to edit the 3D model, which includes editing the mesh and applying textures.


To be able to use the modeller, you must have an S3 license. To get the S3 license, you can visit the LFS shop page.

Entering the modeller

First, follow the instructions how to download and install the LFS Editor.

Once you have the editor installed and run the LFS Editor application, you will be presented with the entry screen.

Vehicle model structure

Modeller uses 3D meshes to represent the vehicle model in 3D space. All meshes are built from three basic structures - points, edges and triangles.

The most elementary part of a 3D model is the point (also referred to as a vertex) which is a single point in 3D space. Points are represented in the 3D viewport in point mode as small square buttons.


An edge always connects two points by a straight line. They are used to construct triangles. Edges are represented in 3D viewport in triangle and point modes as thin lines.


Triangles (often abbreviated to tris) are used to build the actual surface of the object. They are what you see when you render the mesh. If this area does not contain a face, it will simply be transparent or nonexistent in the actual model.

A triangle is defined as the area between three points, with an edge on every side.

Editing modes

Buttons for switching editing modes are located at the top left of the screen. You can also press 1 to 8 on your keyboard to switch between the modes.

Load / save object

At the bottom left of the screen, there is a set of buttons used to load or save an object in the Modeller.
