Actually the icons in world have some sort of glow.

Describe the solution you'd like
I would like to control weather an icon is glowing or not.

Actually I found out the used shader for the images is UI/Default.
This explains why icons on the sign look as they do.

1. The default shader does not respect any light from the 3D scene.
2. I guess the glow effect comes from the bloom effect, which is post processing so effects everything.

Here's a list with shaders

[Info   : Unity Log] ToonDeferredShading2017
[Info   : Unity Log] Sprites/Default
[Info   : Unity Log] Sprites/Mask
[Info   : Unity Log] Hidden/InternalErrorShader
[Info   : Unity Log] Skybox/Procedural

Maybe it makes sense to create a custom mesh for this, which takes two materials, one for the wood and one for the sign.
This would have the following advantages:

• in game lighting
• no blitting effects

This needs investigation of which is the standard material and how to apply it at runtime. Shouldn't be too difficult with the in game editor.
