Learn what FSX vector scenery changes in roads, coastlines and rivers, what mesh cannot fix, and how to solve layering and duplicate-feature issues.
Yes. In FSX and FSX: Steam Edition, vector scenery add-ons can reposition and refine roads, railways, coastlines, rivers, lakes and other mapped features. They improve geographic accuracy only where their source data and coverage beat the defaults; they do not sharpen ground textures or increase terrain elevation detail.
What does vector scenery change in FSX?
Vector scenery changes the horizontal position and shape of mapped lines and polygons laid over the terrain. The same principles apply to boxed FSX and FSX: Steam Edition, although their installation paths can differ.
| Feature | What vector scenery can improve | What it does not guarantee |
|---|---|---|
| Roads and railways | Routes, junctions, classification and alignment with real-world mapping | Custom bridges, moving traffic or every minor road |
| Coastlines and lakes | The boundary between land and water, plus shoreline placement when supplied | Sharper water textures or corrected aerial imagery |
| Rivers and canals | The route and, for polygon waterways, the mapped width | Flowing water, depth or detailed three-dimensional banks |
Coverage varies by package. One vector add-on may replace only roads, while another includes hydrography, railways, dams and bridge objects. Our regional Southern Africa scenery package illustrates how several of those feature types can be combined.
How is vector scenery different from mesh and landclass?
Vector scenery, terrain mesh, landclass and photographic scenery correct different parts of the FSX world. Installing higher-resolution mesh will not move a misplaced road or redraw an inaccurate coastline.
| Scenery type | What it controls | Choose it when |
|---|---|---|
| Vector | Roads, railways, rivers, shorelines and water polygons | Mapped features follow the wrong route or shape |
| Terrain mesh | Ground elevation | Mountains, valleys or slopes have the wrong shape |
| Landclass | Placement of generic urban, forest and agricultural textures | Towns, woodland or farmland appear in the wrong areas |
| Photo scenery | Aerial or satellite imagery shown on the ground | You want location-specific surface imagery |
Our breakdown of FSX terrain mesh and vector layers explains the distinction in more detail. Photo scenery can still show an old road or shoreline inside its image even after the functional FSX vector feature has been corrected; matching water masks or imagery are then needed.
Why do new roads or coastlines look wrong?
Incorrect coverage, overlapping scenery files and poor layer priority are the usual reasons vector scenery produces no visible change or creates duplicate features.
- Check the documented coverage. Confirm that the package contains the required feature class. A roads-only product will not alter rivers or coastlines.
- Confirm that the scenery area is active. Add or enable its parent scenery folder through the FSX Scenery Library. Use our FSX scenery installation procedure if the area is not listed.
- Test without competing vector packages. Parallel roads, doubled shorelines and overlapping rivers usually indicate that two regional or global products are active over the same location.
- Correct the layer order. Keep airport and local city scenery above broader regional vector scenery, regional packages above global replacements, and add-on replacements above the relevant default FSX layers.
- Look for missing exclusions. Layer order alone cannot erase stock roads or shorelines. A replacement package normally needs suitable exclusions; without them, default and add-on features may both appear.
If a package has separate exclusion, water and road layers, retain the internal order specified by its documentation. Airport-specific scenery should normally remain above broad vector coverage so its local exclusions, flattens and roads take precedence.
When is an FSX vector scenery add-on worthwhile?
Install vector scenery when default roads, water boundaries or rivers are visibly misplaced, especially for low-level VFR flying or when they fail to align with photographic scenery. Choose mesh instead for incorrect terrain height, and landclass for wrongly placed cities, forests or farmland.
A corrected road vector does not automatically add road traffic or three-dimensional bridges. Likewise, more accurate water polygons can expose mismatches with old photo textures, nearby airport flattens or unsuitable terrain mesh. We recommend using one principal vector product per region, then placing airport-specific corrections above it rather than stacking several overlapping replacements.
