Orange spot on mesh

Hello all,

After importing a mesh (single mesh), applied the maps (Base color, rough, metal, normal) and building the lighting, I got bright orange sport in the viewport.
They aren’t visible ingame, which is good.
But i was still wondering if anything was going wrong here.

PS : no issue in the 3D model viewer

Got it :
“screen space reflection” was active under Show - Visualize - Screen space reflection
