I’ve already tried to paint the “610gal drop tanks” on the F-15A using GIMP and making sure to implement the changes to the .blk file but they keep the original paint scheme. Are we able to paint them at all, and if so, how?
Currently, there is no way to get any drop tanks re-texture to show up in the game. I don’t know why, but no drop tank can be re-textured until they either fix this or add the functionality.
I’m hoping for it too, but you’ll just have to wait or submit a bug report to see if they know this is a common issue with drop tanks.
