Lighting different on Landscape and Static Meshes for decals

Anyone know a fix for this?

My decal is lit different anytime it overlaps a static mesh compared to my landscape.

Found a solution. I set the decals Normal map to a Constant 3Vector and set it to R: .5 G .5 B: 1.0 for a flat normal. I think ti was trying to pickup the normals of the underlying meshes and getting weird.

Nope. I just realized the rotation of the decal is what makes it look bright or not… hmmmmm
