Engine Nacelle NACA Duct model issue

[LanceCriminal86]

Sometime in the last few patches, I noticed a change in the NACA ducts along the sides of the engine nacelles. It's almost as though there's an issue with the normals or a material. In some lighting these ducts "glow", even though the light is on the opposite side of the aircraft. Sometimes they almost seem see-through or hyper reflective.

 

It's the same on the stock skins and on custom skins.

 

I mentioned this in the skinner's thread but hadn't heard anything and wanted to make sure it was here in the log.

 

 

 

 

 

 

In the model viewer, here's the "Albedo" render mode, note issue doesn't seem to appear

 

Normals mode shows it (but doesn't seem to be present in the actual Normal map?)

 

Roughness

 

Metallic

 

"Diffuse Light" mode shows it:

 

 

There was nothing in the AO map or any of the other render options so I didn't capture them. Trying to add AO shadows in that spot did not fix or abate the issue at all. Still magical glowiness.
