Scenery Objects Tab (Objects)

The Scenery Objects tab (available in the side toolbar) is one of the primary environments in the editor. It handles browsing, placing, aligning, modifying, and attaching all scenery objects (Sceneryobjects) – from buildings, shelters, and fences to traffic signs, signals, and interactive bus stop displays with dynamic text.

1. Library Toolbar

The top of the side panel features utilities for managing the model library:

Button	Function
REBUILD LIBRARY	Rescans simulator directories and completely rebuilds the cache for all available .sco objects from scratch.
OPEN IN EXPLORER	Opens the folder containing the selected object in Windows Explorer.
RELOAD MESH	Reloads 3D geometry (.o3d / .x) and textures directly from disk without restarting the editor.
ROTATE THUMBNAIL	Rotates the 3D preview thumbnail in the library by 45 degrees for alternate viewing angles.
REFRESH THUMBNAIL	Re-renders a fresh preview thumbnail for the selected element.
MARK AS VEGETATION	Classifies the model as vegetation (tree/shrub), enabling it to be used within the vegetation placement system.

2. Search and Browsing Modes

The editor provides a dynamic search system and three alternative library views:

A. Object Search

• Search Scope: Dropdown allows filtering where queries are matched:
  • Path – searches file path strings only,
  • Name – searches object names,
  • Everywhere – searches all metadata (paths, names, .sco groups).

B. Library View Modes

FLAT LISTGROUPS TREEDIR TREE

Displays all objects in a flat scrollable grid with large thumbnails, object names, authors/folders, and favorite star toggles.

Organizes objects into hierarchical folders based on categories/groups defined inside .sco files.

Mirrors the physical folder structure on disk within Sceneryobjects and Vehicles.

C. Large 3D Preview (Big Thumbnail)

Clicking LMB on a thumbnail in the library opens an enlarged interactive 3D preview window.

---

3. Favorites System (Favourites)

A categorized favorites system allows instant access to frequently used assets:

1. Adding to Favorites: Click the star icon next to any object in the library, or drag & drop the object directly onto the quick access bar.
2. Choosing or Creating a Category: Clicking the star icon opens a dialog. Select an existing category (e.g., Signs, Barriers, Shelters) or enter a new name and click +.
3. Quick Access Shelf: Favorite items appear on the horizontal bar across the bottom of the screen with visual thumbnails:
4. Category Management / Editing: Right-click on any object in the quick access bar to open the management dialog:
   • REMOVE FROM ACTUAL CATEGORY... – removes the object from the active category.
   • DROP CATEGORY (red trash can) – deletes the entire category.
   • BLACK CATEGORY NAME BUTTON – reassigns the object to another category.

5. Basic Placement and Replacement

• ADD: (key: N) Spawns a new instance of the active library object under the cursor. Tracks the mouse until LMB or Enter is pressed.
• REPLACE: Enables instant model replacement for one or more placed objects. Select objects on the map, choose a new model from the library, and click REPLACE – objects are swapped while preserving their original coordinates, elevation, and rotation angles!

---

6. Placement Along Spline (Add as spline)

Rapidly places long sequences of repetitive objects (such as guardrails, fences, light poles, or noise barriers) along road or sidewalk paths:

Workflow:

1. Select an object in the library or on the map.
2. Click ADD AS SPLINE.
3. A guide line with a green start node appears in the scene:
   • Click LMB on the ground to anchor the starting point.
   • Drag the cursor – a yellow end node appears, generating a real-time preview of repeated instances.
4. Clicking LMB confirms the segment and immediately begins the next one from the end node (enabling multi-segment fence lines).
5. Pressing Enter confirms the final segment and exits the tool; Esc aborts.

In-Flight Shortcuts During Placement:

Shortcut	Function	Description
+ / = / NumPad +	Increase Spacing (+0.1 m)	Increases spacing (Distance) between consecutive instances by 10 cm along the line.
- / - / NumPad -	Decrease Spacing (-0.1 m)	Decreases spacing (Distance) by 10 cm, condensing placement (minimum: 0.1 m).
R	Rotate by 15°	Rotates all placed instances by 15 degrees around their vertical axis (e.g., facing guardrails toward the road).
Up / Down	Lateral Offset (±0.1 m)	Shifts instances along the X-axis relative to the line by 10 cm (closer/further from road edge).
Left / Right	Longitudinal Offset (±0.1 m)	Shifts instances along the Y-axis relative to the line by 10 cm.
Ctrl (hold)	Node Snapping	Automatically snaps nodes to nearby road spline endpoints.
LMB	Confirm and Continue	Commits the segment and starts a new one from the current cursor position.
Enter / NumPad Enter	Confirm and Finish	Commits the segment and exits placement mode.
Esc	Cancel	Cancels the preview and exits without changes.

7. Attaching to Another Object (Attach to object)

Enables mounting child objects (e.g., sign faces, mileage markers) directly to a parent base object (e.g., posts, masts, gantries):

Technical Requirements:

The parent object must define attachment points in its .sco configuration file:

Example:

[new_attachment]

attach_trans
0
0
2.2

Step-by-Step Procedure:

1. Select the child object to be mounted (e.g., a sign plate):
2. Click ATTACH TO OBJECT – the object highlights in red, entering target selection mode:
3. Click LMB on the parent object (post). The child snaps to default attachment slot 0:
4. In the POINT NUMBER field, you can adjust the slot index (e.g., entering 1):
5. The child immediately repositions to the new attachment slot on the post:

8. Attaching to Splines (Attach to spline)

Binds an object directly to the longitudinal centerline of a road spline ([splineAttachement]):

1. Select the object and click ATTACH TO SPLINE.
2. Hover over the target spline (highlights in green) and click LMB:
3. The object attaches along the spline axis and orients to its tangent:
4. Adjust binding parameters in the side panel:
   • DISTANCE – interval in meters along the spline for repeating instances.
   • RANGE – longitudinal segment length over which instances repeat.

9. Editing Dynamic Labels (Label)

The LABEL tool inputs dynamic text strings on 3D models with defined text textures ([texttexture]):

Text Object Types:

Special ObjectsStandard Text Objects

Displays structured parameter inputs for standardized models (e.g., bus stop timetables, destination boards, platforms).

For standard objects (e.g., bus shelters, direction signs, mileposts), click NEW LABEL + to add text lines: Entered text is rendered onto the 3D model in real time:

10. Transformation and Relationship Properties

The lower side panel displays transform controls for the selected object:

• Coordinates and Rotation:
  • X, Y – horizontal coordinates on the tile (meters).
  • Z – vertical elevation (meters).
  • ROT – rotation around vertical axis (Heading/Yaw in degrees).
  • PITCH – longitudinal tilt angle.
  • BANK – lateral roll angle.
  • ID CODE – unique internal numeric ID in the OMSI map structure.

Snapping Options

• SNAPPING TO OBJECTS: Snaps edges and corners to neighboring objects. The numeric field sets snap tolerance in meters (e.g., 0.00).
• SNAPPING TO TERRAIN: Snaps the base of the object to the terrain elevation beneath it.

Hierarchies and Parent Links

• PARENT TO: ID of parent object (e.g., an intersection crossing controlling this traffic signal).
• ATTACHED TO: ID of base object to which this instance is physically mounted.

Traffic Light Configuration

If the object is a traffic signal, a TRAFFIC LIGHT phase selector appears. If not yet linked to an intersection, the editor prompts: "Parent to crossing first".
