Broken Materials in 931

There is a bug in the newly released 931. When:
  • Clouds are set to stratus and
  • Pixel shaders are on and
  • The airplane has an OBJ that uses ATTR_diffuse_rgb
the attribute is ignored, which typically makes things appear white. The primary example that has been reported to me is the throttle quadrant of the Piper Malibu.

This is simply a bug in the shaders (which is failing to apply the diffuse tinting to ambient-only lighting conditions); I have a fix, but I'm not sure how soon it will be released. We will probably do a small bug-fix release with this and one or two other things, but this is yet to be finalized, since Austin is out of the office this week.
