Material too bright without any lights

Hi there,

I have a scene where I have a terrain and a material applied to it.

My material is mainly orange like this :

I made the project two days ago and everything was working fine until now, this is what I get in the viewport even when the lights are disabled, the material is very bright :

Then if I build the scene and the lights, I get this weird red artefacts :

Any idea of the origin of the problem?

Thanks

Hi,

Thanks for your answer (sorry I am late).
I think the issue was linked to the SkySphere BP that I imported from the default content file.

Have a great day
