Models loaded in Three.js 155dev are dark

[andreasrosdal]

Description

The models loaded in Three.js 155dev are dark. They are loaded using the GLTFLoader.
Using Three.js r154 the models had correctly lighting.

Is there some API change in this build that I need to update the code using Three.js?

Reproduction steps

1. Build Fciv.net using Three.js 155dev.
2. Start a new game.
3. Observe darkness.

Can you please verify if you are affected by #26392?

[andreasrosdal]

Yes, I am affected by #26392

Further, I am using

THREE.ColorManagement.enabled = false;

here: https://github.com/fciv-net/fciv-net/blob/main/freeciv-web/src/main/webapp/javascript/webgl/mapview.js#L69
in order to opt-out of using the new colour model in r152 (described in #25917 where the objects were too bright).

I am interested in doing the correct migrations in order to use Three.js correctly and get as good colours as possible.

Further, I hope to be a good early adopter and tester of new features in Three.js.
