When a material that uses BumpOffset is fed into the Emissive Color of Surface Opaque Default Lit material and then applied to a nanite mesh, a visible seam can be seen along edges and the intersections with other geometry. Disabling nanite (r.nanite 0) will remove the seam.
Steps to Reproduce
1. Open the project in the editor
2. Notice a red jagged line at the seam running between the two intersecting planes
