How di you do this? Please go through the detailed procedure.
Thanks.
Basically I had to redraw the *_t.dds files again, but I was able to take a few shortcuts.
In Photoshop I first deselected the areas I wanted to preserve like the markings, and nose art.
Then I used the levels function to clip the low and high end of the brightness range. This had the effect of reducing the contrast to a fairly narrow range. I then used brightness adjustments to get the shade right, and colorizing to set the tint. In this case a 5% saturated blue grey.
Next I redrew the panel lines with a slightly darker grey, and then applied an overall 2% monochromatic noise filter. Now the textures looked like panels of uniformly tarnished aluminum with the original markings intact.
Then I addressed the *_r.dds files. These were a bit easier to deal with because they were generally just an overall 17% brightness grey. A quick adjustment with the brightness tool to lower this to 10% made the environmental reflections much more subtle and natural looking for weathered aluminum.
For reflective areas of the skin the *_r.dds should typically be in the 10-16% brightness range depending on the *_t.dds luminosity and your personal tastes. (Try something >50% some time just for fun.) For matte painted areas the brightness should fall into the 0 - 5% brightness range.
The tweaks to the M3D involved setting the glossiness to 00 00 7E 43 so that the highlight reflections were fairly tight / narrow rather than diffused over a large area.

As you can see there is a range to the environmental reflections that depends on the condition of the individual aircraft's finish.
