    Distant Mountains

    Hello!

    Who knows the standart MSTS distant mountains viewing distance?
    Does this option show mountains from original MSTS, or it is new OR function?

    It is the latter.

      MSTS near viewing was just 2000m, which meant 4 tiles -- the one you were on and the three closest to the tile corner that was closest to where the camera was located. Beyond 2000m was the start of Distant Mountains and AFAIK the ultimate view limit wasn't discovered; route builders would add 2 - 4 more tiles and that was that.

      In Open Rails the default is/was 9 tiles -- the one you were in and the 8 that surrounded that tile. Recently a number of major improvements have been added that will allow you to specify the near terrain anywhere between 2000 and 10000m and the Distant Mountain Terrain up to 100000m (but you really do need to have DM terrain that far out otherwise a bug will cause it to crash.

      Extending the view distance adds a whole lot of work to do, often crushing frame rates. To help deal with that there is one more option to look into and that's... ahh, I don't recall the name!!! ... something to do with rendering multiple instances of the same model just one time instead of for each one. It does make a big difference but often not enough to get frame rates back to where they were before. And so what that means is each person is going to have to find out for themselves what near distance view value to use and that will likely vary from one PC to another and on the same PC from one route to another.

      Hope this helps.

        The default viewing distances in Open Rails should work well and similar to MSTS. The distant mountains shown in OR are the same as those in MSTS (the way they're displayed isn't the same, but the data is the same) so they'll only work on routes which had distant mountains in MSTS already.
