This happens also in other routes, and is probably due to the minimum distance DM are drawn. This was 1300m for a standard 2km standard terrain viewing distance, and is now fixed to 500 m.
I don't want to always bother James with the Bernina route :sweatingbullets: , hence here is an example from route SUD-ITALIA_01 (Tirrenica Meridionale V2).
This is how it looks now:
and this is how it looked with V09:
In my opinion the cutoff distance could follow following rule
500m < Viewing distance - 700m <1300m
because it can be supposed that normal terrain has been created in the route at least up to 1300m distance from the tracks.
Anyhow with Viewing distance < 2 km the probability to view artifacts should be higher.
Also the possibility of defining how many meters to lower the DM, that now is no more present, was of help in some cases.

Hi Walter,
there is no bug report on this.
There was this bug report by myself
https://bugs.launchp...or/+bug/1213712
but it was closed after James set the cutoff distance at 500.
By the way another reason why such problems were scarcely noticeable in MSTS is that MSTS draws the terrtex on both faces of the DM terrain.

Walter, basically it's a DM bug in the route if you can see gaps (it occurs when the DM terrain rises above the normal terrain and you have that particular location at the cut-off point for terrain drawing, either 500m or the viewing distance). We have a limited set of bad options for trying to hide it when it happens.
I didn't know MSTS did that, but we can easily do the same in OR.

I think that would be nice! Here is how MSTS does. This is the place where the standard terrain ends (it's far away from the tracks). The DM display begins at a certain distance,as in ORTS, so you obviously see a gap. But as can easily be seen the DM display is doubleface.
I would add that artifacts as those shown by Walt not necessarily are DM bugs. One must remember that the DM mesh is much larger than standard terrain mesh, so it can easily happen that at a specific point DM terrain is higher than standard terrain.

Please try X.1803; I've made the near-plane for low-resolution terrain vary from 500m to 1500m using viewing distance - 500m, and enabled double-sided drawing of it.

Cool, glad that worked. It's always a bit uncertain how such changes will affect that hundreds of thousands of miles of railway available to people. :pardon:
