    Seems I need to read up on EOT as objects in ORTS.

    8.18. EOT - End of train device

    I also kind of wish I knew what the air-powered battery charger sounds like.

      I can see what I can do, if I come across a newer EOT..

        I finally started on it this afternoon. The story so far. For now, I'm using the sound of escaping air from a pressure vessel. I can see that the newer devices have an alphanumeric display and smooth cases, while the older variant has just a 2-digit 7-segment LED with some castellated edges. I'm going to opt for the newer version.

            Pete, I wonder what all of those chamfered edges cost polygon wise? What number are you getting for polygons? The old EOTs were pretty basic and economical in terms of polygons.

              Mine comes in at 2,035 triangles with a single draw call and 0.13 kujus according to shape viewer, which is less than the MSTS default US2 Hopper car.

              My question is how do you get the end of the hose from the EOT to match the trailing brake hose on any piece of rolling stock?

              Keep working on yours Pete, I have stopped further work on mine as this was just a diversion from what I would really be working on. I can upload the source files if anyone wants to have a play. Model exports as both .S and .GLTF.

              Cheers,

              Marek.

                Hi Marek,

                BEAUTIFUL - funny - we used to build entire freight cars with that number of polys - how times change.

                  My idea was to generate a high poly master to create the Ambient Occlusion map to add to a lower poly version.

                  And, explain to me how a modern EOT device is *not* treated like a freight object using someone else's wheels and brakes... :-)

                    Is there a hole that flashes a light, to signal the rear of a train on this device (like a F.R.E.D.)? I assume it is an ultra bright LED with a 100K hour life.

                      On reflection, this would be a FA, but how would that work with the current OR setup? Messy to say the least. So I guess like other current OR/MSTS EOT devices it is a freight car of some sort and yeah, BIZARRE!!! The worst part is and has always been that tagging the Camera #3 to that EOT results in a VERY shaky/unsteady image, as it bounces around like a basketball when the consist is in motion. I suppose that happens because the mass is very small, and who knows how many fake wheels are attached to this EOT device.

                        Well, there are specs for EOTs in the OpenRails Manual, but I'm not yet convinced about the best way to define it.

                          Hey Pete,

                          The EOT release I did includes an SMS file for the little air turbine. It should be reasonably accurate for your EOT. There's a few different kinds of EOTs I wanted to make for a planned set 2 (including this one), but I haven't had the time, so I'm glad you're having at it!

                            Thanks Scott. Yeap, times change and thankfully in this hobby you can either change with the times or stay back in time, something for everyone.

                            Good to see you back and compliments on your coding work.

                            Cheers,

                            Marek.

                              No hole, I didn't even know there was a hole, I know little about EOT's in general and my first exposure to this particular model of EOT was the images in this thread.

                              As advised, this is not complete, it was just a diversion for me, I have no use for it on 'my' railway coupled with the fact I don't spend a lot of time watching the end of the train.

                              Project files (Blender 4.5.1 and GIMP 3.2.4) sans reference images are in the attached zip may pique someones interest. Do as you wish with them.

                                Hi Marek,

                                Thanks buddy - this was a path I was reluctant to take. It started as just a couple of tweaks for my own use.

                                Now I just code - I can’t remember the last time I opened ORTS to run a train or open Blender to work on one of my many incomplete models. Well over a year now.

                                I guess those that can - should?

                                We are in dire need of some improvements. It seems the bulk of the interest and work in ORTS seems focused on minutiae - while the bigger picture has been pretty neglected for years.

                                Keep up the good work - always a pleasure.


                                Regards,
