Metal environment problem with Trainzmesh

[aurelien031]

Good evening everyone,

I just upgraded to SP6 on my 22PE, and I've noticed that several of my trainzmzsh creations have a problem with the ".m.reflect" metal environment. It appears with a greenish tint. What should I do?

Thanks in advance. Sincerely, Aurélien

This is due to those assets having an issue with the textures associated with m.reflect, metal environment. In previous versions, Trainz ignored the problem. If hadn't noticed before, what was supposed to be a metallic texture was dull grey or appeared white.

Even if m.reflect materials were correctly made in pre-TRS19 assets, they are not reproduced properly in TRS19 or TRS22. Quite a disappointing performance by the Trainz developers in my opinion.

Good evening, thank you for your replies. What should I do then? Sincerely, Aurélien.

I think the green tint in TRS19+ is an indicator of incorrect material setup of m.reflect in the original asset. You could investigate that and correct it, but since you are using TRS22 and it can’t properly reproduce even a correctly-made m.reflect material, that effort seems like a waste of time.

You would probably better off updating your creation to a build 4.6 (or higher) asset with proper PBR materials. Have a look at the Wiki and see what PBR material is likely to support the type of reflection you want. I suggest m.pbrmetal with a strong metallicity component, but there might be better options available (I haven’t checked the Wiki for a while).

The green tint might be a sign of the m.reflect material missing a diffuse texture.

Hello Aurélien,

For me, a fully reflective PBR material never looks as good as it did with m.reflect.
I mentioned this some years ago:

Maybe I should have experimented with the roughness value.
