Hi everyone,
I'm a new user of GIMP so apologies if I have missed something obvious. I am trying to make a texture file (skidmarks on a road). I need only the rubber tyre markings to be visible on an otherwise transparent image so it blends into the base road texture underneath (hope this makes sense). The file type must be DDS for best in-game performance (PNG is hardware intensive to render, DDS is not). The image I have made exports perfectly to PNG, with black tyre marks on a transparent background, however when exporting to DDS format it outputs a completely black image.
I have tried all possible DDS output combinations (compressions and formats) with no improvement. I believe the best output should be using "Alpha Exponent (DXT5)" compression option but happy to be corrected on this. Not using Mipmaps (but should I? If so, how?).
I have tried many different combinations of Alpha layers, image layers, Alpha channels etc.
Screenshots of my latest attempt below (working PNG output, fully black DDS output)

Can anyone point me in the right direction?
Let me know if you need me to provide any more info.
Thanks in advance!
