Gameplay patch 5 (DEM import)

Diesel Railcar Simulator · published 24 Jun 2026, 17:25 UTC · build 23843657

All newsPlayers around this dateRead on Steam

The fifth gameplay patch is now live with the following changes:

Visuals

  • Fixed a problem with train cars sometimes briefly appearing in the wrong position
  • Fixed LOD building for train cars to happen behind the scenes instead of overlapping the base model
  • Fixed discontinuities in normals and texture coordinates for some models generated from cross sections like road surfaces
  • Fixed material colour loading from .mtl files (fixes Class 205 cable colours)
  • Fixed custom materials to use smoothness slider value when also using a metallic/smoothness map (was previously always 100% causing a shiny surface)
  • Fixed possibly missing custom models on the Laguna Paiva workshop route
  • Possibly fixed grass sometimes being loaded only partially
  • Restored some brown vegetation near the North Landen portal

All editors

  • Fixed editor side panel bug where a wrong item would be shown after selecting an option from a list
  • Fixed parsing of certain length and position values to only accept decimal period (instead of comma) in some editor fields, regardless of the operating system setting

Train editor

  • Fixed train editor to highlight some parts of the models correctly when hovering over with the mouse pointer
  • Added 3D-gizmo

Route editor

  • Fixed grids to remain intact when increasing divisions by more than one at a time
  • Fixed adding a new grid to also open the model node parts of the properties on the side panel
  • Fixed terrain triangulation not being triggered when adding a new terrain node on top of an existing edge
  • Fixed a possible crash when adding or removing terrain nodes
  • Attempted to fix a possible crash when quickly updating terrain presets or other types

DEM importing


The route editor now supports two methods of importing digital elevation maps (DEM):

  • Adding a grid, loading the height of its nodes from a greyscale image file and converting them into terrain nodes
  • Loading terrain nodes directly from a text file (through the route properties side panel option)

See the route editor guide DEM chapter for more information:

Miscellaneous

  • Fixed a rare signal animation related crash
  • Unified cab control and train editor model highlighting. The old outlining method for cab controls had performance issues
  • Removed option to reference models from other vehicles and routes (as a model source)
  • Removed legacy pack support (not the newer "pack2")
  • Optimised grass rendering memory consumption

What's next?


Another patch coming soon
