Look at F14\Textures\LOD
there is a DDS there called 3in1
you need to make a copy of it in your livery (if not already present) and copy your texture over the original.
to save some time, you can open your already baked DDS, check load MIP in layers and grab MIP3 that's exactly the correct size you need (sometime you'll need MIP2). just copy the layer over to 3in1 and position it over the original you want to override, then just save the thing and update the descrition.lua (if you don't have it done already).
