Switch to underground mode and watch an empty tunnel. Wait for a train to enter. You will see only the smoke, but not the train.
If you switch to normal mode and back to underground, while the train is in the tunnel, then you can see the train normally.
Is this the sliced underground mode or the full underground mode?
Full undergound, I didn't test with sliced mode though
In which case, I am afraid that I cannot reproduce this, at least not on the single threaded Windows build that I am now running to run certain tests. Are there any particular conditions required to reproduce this?
I have noticed this on the offline copy of bridgewater-brunel game. There is a long double track tunnel, with several signalboxes over it, where I saw this happened = jsut while I was testing if the rotate bug was fixed.
It is that very saved game that I am using to test - can you give me the co-ordinates of where this occurs?
tunnel entrance at 817,1055 near Hadfield city
I see it now with that tunnel. That is exceedingly odd - I am not quite sure what would cause that or where to look to test for it, since I have never (or, at least, I think, hardly ever) looked in any detail at the code for determinng whether vehicle graphics are displayed.
Sliced mode is OK.
Very odd indeed.
