Does Open Rails use the .sd file data to set the distance between wagons/cars for coupling?

Hi David,

Nope. I believe the only current ORTS use of an SD file is to control the Bell Animation speed on steam locomotives.

It does respect the ESD_Display_Level() value. I routinely set my tools objects to ESDL(10) and when running OR set the display to level value at 9. Everything from 0 to 9 displays but not 10.

FWIW ALL placed objects in my work follow a standard sequence of display levels... tools highest, vegetation next, misc stuff, then buildings are at 3, interactives are 2, roads 1, track 0. If I were to recast those today I'd put buildings 5 and spread out road and track items across the lowest five values (0 to 4).

Both TSRE and MSTS RE sort the world files by this display level and many, many times I've found that to be useful.

Thanks. How is the distance between wagons in a consist set in OR? In MSTS, this is done with the Bounding Box entry in the .sd file.

Hi David,

It's just the [Size] entry in the ENG/WAG. The coupler slack plays into this via the [r0] value in the coupler block - as you can have the size set way too small with way too large values set for r0... Keep in mind ORTS only uses (1) Coupler Block...

If you look at the WAG files for that USRA Box paint kit I uploaded (which apparently was a complete waste of time) - I tried to distill everything out that wasn't needed by ORTS - it's surprisingly brief...

Hi Dave,

Sounds cool - so how do your set ORTS to display a specific ESD level ?

It's done on one of the options tabs... I think video.
