Orca command pod is green around the edges when viewed from a distance.

I'm not too knowledgeable when it comes to models, but it seems like it could be something to do with the texture scaling down as the camera moves further away. You can see it in this image (taken with all graphical settings maxed out, 1920x1080 resolution, borderless window, 64-bit, and at the farthest away zoom in the VAB) around the edges of the boxes that come out of the underside of the pod, as well as where the long rectangular section with the attachment nodes attaches to the upper part of the pod.

There's no green when you zoom back in, as seen here:

I should also mention that this is the only part, USI or vanilla, that does this, everything else looks fine while zoomed out.
