Texture banding issue

Version: 1.37.19.0

Frequency: Consistently

Severity: High

Context: In flight

Bug description:
We’re observing a hint of darker shading. Maybe AO?. It appears that these lines align with the geometric edges. I experimented with this on a current project, applying only a material with any maps plugged. The problem was there. I don’t recall encountering this prior to SU15,maybe I’m wrong.

**Repro steps:Select any aircraft and fly. Screenshot are from TBM on ground
