MM: It's the wrong trousers, Grommit!
It's 'cause I'm in the middle of retexturing the valk - the upper half is sporting nice new properly weathered textures, while the legs are still wearing very basic textures I did when I still intended to turn it into a VF-1S Hikaru...
Dat: Yeah, it's the GI rig. I'm not positive what causes that, but I suspect that that patrticular rig is making more evident the effects of the edge normals. Those bay door surfaces are basically single rectangles with the edges set very soft - so the entire poly is blending out the curvature of the edges where the "front" meets the 4 "sides". I get the feeling that tweaking those edge normals would fix it - though I don't know if I will, I kind of like the effect....
