So, with Fencer, Oboe, Devil, etc. showing some pretty impressive mottling for NMF, along with my slightly better understanding of how the new spec maps behave, I decided to attack my first skin again. The progress has been hit and miss.
I was able to get mottling in and some panel color variation but the skin seems too white. But when I toned it down I lost some of the effects. (Perhaps that's a good thing.)
Here's what it looks like. Is this now too dark? I definitely think it looks better with the sunlight reflecting off of it than it does without. I believe the photo in flight (Mustang 00.bmp in the file list) is what it looked like about five percent lighter...
The wing still washes out some in light.
