You can load either an existing object made in the LFS editor, or an external model in OBJ format. The corresponding buttons are located in the bottom left corner of the screen:

== Vehicle model structure ==
  
−
=== Loading an entire vehicle made in LFS editor ===
+
Modeller uses 3D meshes to represent the vehicle model in 3D space. All meshes are built from three basic structures - points, edges and triangles.
  
−
An existing vehicle model can be loaded into the modeller by loading a vehicle in the [[Vehicle Editor]] and switching to the modeller by pressing {{key press|E}} or clicking the {{old button|E - Edit Model|#a1a1ff}} button.

=== Points ===
  
−
=== Loading an object saved in LFS editor ===
+
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|point mode]] as small square buttons.
  
−
To load a standalone object saved from the modeller or the [[Vehicle Editor]], enter the modeller in a standalone mode from the LFS editor entry screen and then click the {{old button|LOAD|#00ff00}} button at the bottom left of the screen. Such object can be either the main object (car body) or a subobject, like a steering wheel.
+
=== Edges ===
  
−
=== Loading an external OBJ file ===
+
An edge always connects two points by a straight line. They are used to construct triangles. Edges are represented in 3D viewport in [[/Triangle Mode|triangle]] and [[/Point Mode|point]] modes as thin lines.
  
−
If you have a 3D model in [https://en.wikipedia.org/wiki/Wavefront_.obj_file OBJ format] that you want to import into the modeller, you can load it by clicking the {{old button|OBJ|#ffffa1}} button at the bottom left of the screen. The file must be located in the 'data\obj' directory and must have a '.obj' extension.
+
=== Triangles ===
  
−
The OBJ file must be exported properly to be useable in the LFS editor. You can read about [[LFS_Editor_Guides#Importing_from_other_3D_modelling_software|importing from other 3D modelling software]] on the [[LFS_Editor_Guides|guides]] page.
+
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.
  
−
==== Warning about licenses ====
+
A triangle is defined as the area between three points, with an edge on every side.
  
−
If you are using a file made by someone else as part of your model, even if you modify it, you will need to declare this when you upload your mod.
+
== Editing modes ==
  
−
You will need to specify the license that the original creator applied to the model and provide information such as the name of the creator and a link to a website where the license information is displayed.
+
Buttons for switching editing modes are located at the top left of the screen. You can also press {{key press|1}} to {{key press|8}} on your keyboard to switch between the modes.
  
−
If no license is stated, by you or the original creator, you cannot upload the mod!

LFS Editor
Vehicle Mods

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

LFS Editor entry screen
Modeller start screen - standalone mode

Requirements

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. Click the Modeller button to enter the Modeller.

The modeller can also be entered from the Vehicle Editor by pressing E or clicking the E - Edit Model button on the right hand side of the vehicle editor.

General modeller tips

  • Press ⇧ Shift + F to temporarily hide the editor buttons.
  • To reduce clutter, use hide selected to temporarily hide points and triangles, then unhide all to show the again.

User interface

The modeller interface consists of the following parts:

  1. 3D model view
  2. editing mode selector
  3. editing mode specific controls
  4. load / save object
  5. special view modes and view options
  6. common editor view controls

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.

LFS editor mesh parts.jpg

Points

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.

Edges

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

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.

subob Subobject Mode
tri Triangle Mode
point Point Mode
build Build Mode
map Texture Mapping Mode
cutout Texture Cutout Mode

view View Mode

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.

If you have an subobject selected, another row of buttons appears, allowing you to load or save the current subobject.

Load / save object buttons
subobject Indicates that a subobject is currently selected
load Load a new subobject, replacing the selected subobject
save Save the current subobject as an object in data\3dob
main object The name of the main object
LOAD Load a new object from data\3dob
SAVE Load the main object to data\3dob
skinXFG_DEFAULT Click the skin name (e.g. XFG_DEFAULT) to select a JPG image in data\skins to use as a skin in the editor
OBJ Load an OBJ file from data\obj
