Hello.

Thanks for the permission. If I understand correctly, the model is traditionally made in 3ds Max format and the finished model will be converted to glTF 2.0 format instead of shape format?
Sorry, English is not my native language, I use Google Translate. If I sometimes use slang words or Hungarian railway terms, I turn it aside.

Sincerely, Laci 1959

That's correct :). And no worries, I'm aware that English is quite hard for a lot of people, but sometimes Google Translate messes up and produces sentences that are hard to understand.

glTF support is already in unstable. I have not yet added means to tag the externally animated elements like individual wheels or bogies, but internal animations already work, the code should recognize the same names as for the stf files.

Excellent news!

Now all we need is a .s to glTF convertor.

That is not necessary, since .s works as before, and it will so for the infinite future.

Hello.

According to them, will an old model work with the old shape format and a model created with the new glTF 2.0 editor with its own format?
Can a model created in Max format be converted to shape or glTF 2.0 format? The first, of course, doesn't make much sense after that.

Sincerely, Laci1959

The .s format model will continue to work in Openrails indefinitely, so there is no need to convert them to glTF. The Gmax editor may not have a glTF exporter, it is a quite old program. (I'm not sure about this, of course, this is just an assumption.) But all currently actively developed 3D editors should have a glTF exporter available, I believe.

By the way, main differences that may affect the edited models:

1. If I know right, .s uses -Z forward, +X right, +Y up coordinate system. While the glTF, by its specification, uses +Z forward, +X left, +Y up.
2. glTF uses the sRGB color space for its base color textures, while the .s is linear RGB.

Please all you guys keep this in mind when exporting models to various formats.

Hi all,

Finally I have been able to finish up the machine to a status that I was able to make a first glTF export with 3DS max, with it looking like this:


However, the shape doesn't show yet in OpenRails, but in the log I find the following error:

I guess the glTF export is not completely correct for OpenRails yet, or I made an error in referring to the shape in my .eng file.
Anyone who has a guess at the error? If needed I can provide the model and eng file to someone who wants to look into it.

I guess that's because the glTF change is not present in the current Unstable Version as shown here at the end of the log.

It's been blocked automatically because it now conflicts (very slightly) with a change that has been made to the Testing Version.

I am hoping that GPZ will be able to resolve the conflict, so glTF will once more be available.

[Rj Zondervan]

Ah, that would explain it. I'll check what unstable version I should have to test run my model.

EDIT: That indeed worked, as shown by the screens below.
There are few things to fix in the export (the normal maps are rendered a little too subtle for my taste, some parts are too reflective), but overall I'm not unhappy. Next up would be getting the animations working I guess.

Hello.
My congrats: today is railroad emploee's day (professional holiday)
And Your "child" have performed first excursion out of engine house.
As it goes very usual, check model's origin hight: it's again 5cm lower,
So the wheels are sunk in rails.
