within the GE aerial images white appears correct, i really havent a clue as to why whites render grey, the background of the .jpeg logo's in this model are white, or near white, i havent tried different image types, .img, .png possibly could render differently (though i doubt it)
i noticed its the same for openGL or Directx , the same for the different video cards/drivers i have used also.
perhaps it is a application mask for some irritable little rendering bug.
the lunar module texture in the model, i will try to find another with color so that it shows up a bit more.
here is another render problem i noticed a few days back,
in GE sketchup if you create a component and then use the scale tool -1 to create a mirror of it, the mirrored component renders black in GEv4.
i also opened a file created with SUPro demo in GE SU, exported to GE and the same the mirrored component rendered black, went back to both programs and in SUpro exploded the mirrored component and in both instances they rendered correctly.
a mirrored component exported with SUpro does not render black, though you dont get textures either.
