 ===== Creating a Superstructure =====
 To make it as easy as possible for users to get started, we recommend using an existing Superstructure that is already included in the Modding SDK.
-However, for advanced users who want to understand how a Superstructure is created from scratch, the following steps explain the manual process.

-===== Explaining the Superstructure Contents =====
+===== Using Custom Meshes for Superstructures =====
+If you want to use **custom meshes** for your Superstructure (for example rails, clamps, sleepers, or ballast), it is highly recommended to base them on existing assets from the SDK.
+To do this, you can export the original meshes from Unreal Engine back into **FBX format** and use them as reference in your 3D software (e.g. Blender).
+This helps ensure:
+  * Correct origin placement
+  * Proper scale and orientation
+  * Compatibility with the Railtool and Superstructure system
+A detailed guide on how to export Unreal assets can be found here:
+  * [[manual:subwaysim:map_construction:export_assets|Export Assets back to .fbx]]
+Using reference meshes greatly reduces alignment issues and avoids unexpected behavior when assigning custom assets to a Superstructure Data Asset.

+===== Superstructure Contents =====
+In this section, we explain how a **Superstructure Data Asset** is structured and which information it contains.
+The Superstructure defines all fundamental properties required by the Railtool to generate tracks correctly.
+It controls the visual appearance, physical layout, and functional behavior of the railway infrastructure.
+The Data Asset is divided into **three main sections**:
+  * **Base Settings**
+  * **Switches**
+  * **Third Rail**
+----
+===== Base Settings =====
+The **Base Settings** section contains all fundamental information required to create standard track segments.
+==== Base Settings Overview ====
+^ Property ^ Description ^
+| **Rail Material** | Material applied to the rails and visible track geometry. |
+| **Clamp Normal** | Static Mesh used for standard rail clamps. |
+| **Guide Rails** | Additional guiding rails for special track sections. |
+| **Gauge** | Distance between the rails. |
+| **Sleeper Spacing** | Distance between individual sleepers. |
+| **Sleeper** | Static Mesh used for sleepers. |
+| **Ballast Offset** | XYZ offset applied to the ballast mesh. |
+| **Ballast** | Static Mesh used for the ballast bed. |
+{{:manual:subwaysim:creating_superstructure:super4.png?direct&800|}}
+==== Rail Material ====
+Defines the material applied to the rail geometry.
+==== Clamp Normal ====
+Specifies the Static Mesh used for standard rail clamps.
+==== Guide Rails ====
+Guide Rails are additional rail elements used in:
+  * Switches
+  * Tight curves
+  * Special track sections
+They are also known as:
+  * Guard Rails
+  * Guide Rails
+  * Zwangsschienen / Führungsschienen
+=== Guide Rail Data Layer ====
+Guide Rails are defined using a **Data Layer Asset**.
+=== Guide Rail Parameters ====
+^ Property ^ Description ^
+| **Name** | Name of the Data Layer asset. |
+| **Guide Rail Distance** | Distance from the standard rail. |
+| **Clamp** | Holder mesh for the guide rail. |
+| **Material** | Material applied to the guide rail. |
+| **Start Mesh** | Mesh at the beginning of the guide rail. |
+| **End Mesh** | Mesh at the end of the guide rail. |
+| **Cm to UCoordinate** | Conversion factor for UV mapping. |
+| **Profile** | Procedural cross-section definition. |
+{{:manual:subwaysim:creating_superstructure:super4_1.png?direct&800|}}
+=== Guide Rail Profile ====
+The profile defines the procedural geometry of the guide rail.
+=== Important Notes ====
+  * All distances are defined in **Unreal Units (cm)**
+  * Incorrect profiles may cause visual or collision issues
+----
+==== Gauge ====
+Defines the track gauge.
+Standard gauge:
+  * **1435 mm**
+  * **143.5 cm (Unreal Units)**
+----
+==== Sleeper Spacing ====
+Defines the distance between sleepers along the track.
+----
+==== Sleeper ====
+Defines the Static Mesh used for sleepers.
+----
+==== Ballast Offset ====
+Defines the XYZ offset of the ballast mesh.
+----
+==== Ballast ====
+Defines the Static Mesh used for the ballast bed.
+----

+The **Switches** section defines meshes and parameters for automatically generated turnouts.
+==== Switches Overview ====
+^ Property ^ Description ^
+| **Switch Guard Dist** | Guide rail distance at switch exit. |
+| **Clamp Mini Inner** | Small clamp at switch start. |
+| **Clamp Blade** | Clamp for switch blades. |
+| **Clamp Guard** | Clamp for rails with guide rail. |
+| **Clamp Single Inner Half** | Inner single clamp. |
+| **Clamp Single Outer Half** | Outer single clamp. |
+| **Hollow Sleeper** | Sleeper with internal linkage. |
+| **Switch Motor** | Motor mesh. |
+| **Manual Switch Lever** | Blueprint for manual switches. |
+| **Switch Blade Throw Bar** | Blade linkage. |
+| **Clearance Marker Mesh** | Clearance marker mesh. |

+===== Third Rail =====
+The **Third Rail** section defines the power rail system for electric vehicles.
+If no Third Rail Data Layer is present, vehicles will display:
+**"No Power"**
+==== Third Rail Overview ====
+^ Property ^ Description ^
+| **Third Rail Begin** | Start mesh. |
+| **Third Rail Mid** | Looping mesh. |
+| **Third Rail End** | End mesh. |

+==== Important Notes ====
+<WRAP center round important>
+  * Third Rail Data Layers are required for powered tracks
+  * Incorrect offsets can lead to power loss or misalignment
+</WRAP>

+===== Next Step =====
+With the Superstructure configured, all fundamental data required for track generation is now available.
+In the next chapter, you will learn how to use the Railtool to actually place tracks, create curves, switches, and define railway layouts on your map.
