I'm trying to create a gauge that reads Turbine %RPM (Left and Right) in each engine. The gauge works fine, however when I try to add a mask image to the '%RPM meter' strips, the strip completely disappears.I tried to create the mask image using Paint and Gimp, however every time I color the Mask Image with two different colors (0,0,0 and 1,1,1) it all just seems to blend into one (0,0,0); therefore making the whole thing transparent. Can anyone explain to me how to create mask images using Paint or Gimp?Is it not keeping the color properties because it needs to be 36bit? I'm really lost so plz help

Make certain you are using 24bit RGB mode, and not 8bit Indexed Color mode. After creation of the mask, you can then reduce from 24-bit RGB to 8bit Indexed Color mode.
