Troubleshooting

RWDecal is written in Python which is then compiled into an executable to make it easy to distribute. Some of the python modules are written in C++. In some rare cases you may need to install the Microsoft Visual C++ Redistributable package.

Known Bugs

Bug #6:

Placing many decals in a route can result in a "Something bad has happened" RailWorks message
Versions Affected: Not version specific
Cause:

This is a fault with RailWorks and not the fault of RWDecal. If you experiance this problem please report it Rail Simulator support.

 

support@railsimulator.com

Temporary Solution:

The fault seems to be memory related. When driving a route with a large number of decals in it, as you go along decals are loaded. It appears that decals are not removed from memory and so after a while you may run out of resources and cause a crash.

 

As decals are meant to only be left in during the design stage and as it takes approx 40 miles of driving (in my experiance) before the error happens, it is still possible to test routes with decals in place for large distances.

 

Decals should be removed from a route after objects have been placed.

Status: Waiting for Rail Simulator to resolve

 

 

Bug #5:

After placing many decals in RailWorks new decals render completely in black. Sometimes RailWorks crashes when this happens
Versions Affected: Not version specific
Cause:

This is a fault with RailWorks and not the fault of RWDecal. If you experiance this problem please report it Rail Simulator support.

 

support@railsimulator.com

Temporary Solution:

IT seems to be related to not enough texture memory so the chance of this happening can be reduced by doing one of the following:

  1. Always use chunks and not full decals and make sure you change the decal quality setting to low (setting is on the Preferences menu)
  2. If you don't intend to leave decals in your route when you have finished creating it then only place decals to cover relatively small areas (less than 10km for example). When you have finsiehd laying track, trees, roads etc simply remove the decals.
Status: Waiting for Rail Simulator to resolve

 

Bug #4: Flashing decals when they overlap
Versions Affected: Not version specific
Cause: This is a fault with RailWorks and not the fault of RWDecal. Overlapping decals have "Z fight" for who can be on top. This is an issue with RailWorks and nothing to do with RWDecal.
Temporary Solution: Do not overlap decals
Status: Waiting for Rail Simulator to resolve

 

Bug #3: Fatal Exception if users select the same latitude or the same longitude for both the Lower Left and Upper Right coordinates
Versions Affected: 2.0.6
Cause: RWDecal fails to detect this user error when you click "Run" and allows decal creation to start. After the first stages of decal creation you get the fatal exception message.
Temporary Solution: Do not select the same latitude or longitude values for your decal in the lower left or upper right boxes. This would create a zero sized decal which is impossible.
Status: Resolved - Upgrade to version 2.0.12 or later

 

Bug #2: Fatal Error when configuring the RailWorks, Developer or Product folder locations
Versions Affected: 2.0.6
Cause: RWDecal checks to make sure that the paths you select are likely to be correct. IT does this using regular expressions that are case sensitive. So if there is a difference in case for the RailWorks path you select for any of the locations then it thinks you are selecting a folder outside of the RailWorks path.
Temporary Solution: Make sure you do not copy and paste paths when trying to select folders. Only select folders by selecting them using the dialog options.
Status: Resolved - Upgrade to version 2.0.12 or later

 

 

Bug #1:

Fatal Exception occurs towards the end of decal creation if you create markers for chunks but no markers for the full decal.
Versions Affected: 2.0.6
Cause:

Reference to a variable in RWDecal before it is assigned

Temporary Solution: Make sure you always create at least "Corners" or "Centre" marker for all decals you create.
Status: Resolved - Upgrade to version 2.0.12 or later
