A Dutch steamengine Let's see what glTF would mean for some models

This resulted in me taking the challenge of creating PBR textures for the machine, as it has quite a lot of bare metals (mainly copper and brass, but also a lot of bare steel).
Now, a few screenshots of how that turns out:
In these screens we can see most clearly the following effects:
- The effect of glass with reflections
- The effects of a bump map and a combination of metalness and roughness maps on the fire chest and the cab, combined with a dented normal map to mock irregularities in these flat sheets of metal.
- The effect of a rough, but bare crown of copper on the exhaust
- Bare metal with a normal map to show have a small indent for letterings (the number plate (bronze) and the factory plates(brass))
Here we see through the spokes of a wheel a leaf spring that is made with a normal map.
And finally a render of the engine. It shows clearly the brass effects on the steam dome and safety valve casing. Also, it shows the oil lamps with brass rings, copper chimneys and a first attempt on a mirror
Overall I am quite pleased in how this is turning out. However, I have still a lot to do, with most noticable that I have to create the same kind of textures for the tender, and I have yet to start working on the 3D cab, but that I can finish after releasing a public beta.
I also have some questions regarding some parts of the implementation of glTF in OpenRails, primarily on animations (Will the naming convention for the animated parts be the same for example) and lights, so I will try to follow Peter's project closely, and keep track of what I would have to change.

From one steam locomotive modeler to another - that's some mighty fine work there - sir. Nice render.
:)
Yeah - PBR textures hold a lot of promise - it was a game changer when introduced into the Flight Sim community.

Please think about posting a tutorial about how to texture like that.

I would like to ask for pictures to show me as the way of the future in a Facebook group.

I'm working on it, but keep in mind that it will be based on a model in 3DS Max with textures made in Paint.NET, so it might be not really applicable to your model or texture editor (certainly Adobe will have some tricks that are way easier, but I tend to avoid software made by Adobe).

Hi,
I'm not completely sure what you are trying to ask. If you want to use my screenshots in a facebook group: feel free :), I made this topic to show you all what could be with glTF support, so it would be fair if anyone can use the screenshots to spread that notion ;).

Anyway, well done!

The series were indeed designed by Beyer Peacock, and the screenshots are also of one of the 36 engines built by Beyer Peacock. However, the designs were given in property to the 'company for the exploitation of state railways' in the Netherlands and later on passed to it's successor 'Dutch Railways'. This means that another 53 engines were built by Werkspoor in the Netherlands, 5 were built by Henschel in Germany and 10 by Hanomag, also in Germany between 1910 and 1921.
The engines turned out to be such a success that in 1928 a slightly modified series of 5 was added, built by German factory Schwartzkopff.

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.

The first 36 units were build by Beyer Peacock.
Others were build by Werkspoor (Amsterdam, Netherlands) (48), Hanomag (Germany) (10) and Henschel (Germany) (18).
Later orders were placed at Werkspoor (1921, 6) and Schwarzkopf (1928, 5).
The last engine was withdrawn in 1958 and is now in the Dutch Railway Museum (no longer operational).
