I assume that it is the REP that changed the environment settings to make many things look nice, but it appears overdone in areas. Flat paint military schemes, textures that are set for no reflectivity etc show plenty now. Is there another that is toned down a bit. ..........snipped
I believe that is the envmap.bmp found in FS9/Texture folder.
I've tried many, but for my eyes, the best was one done by Bob Rivera way back during the A-26 project. The only place it was ever offered was in one of his posts during the project. It also contained a new glass_t.bmp for the nose of the a-26.
If you save lots of stuff, the filename is: Glass Texture and envmap.zip
Bob officially released a couple other envmap.bmp's since. I still like and use the original.
the specs of this particular bitmap are
