Painted originally in Photoshop for FSX

edwardbarnett

I have a paint for my C182 that I made in Photoshop and used in FSX. Now I have P3d v4 and I want to use this paint, but I don't have Photoshop right now, so I'm trying to use Gimp to convert it to .dds, but I can't find the right settings to make it display properly in P3d. In Photoshop I used 888 8 without inverted mips, but in Gimp I don't have that option. How do I convert this .png file to the corresponding .dds file so that it displays correctly?
Any help you guys can provide would be greatly appreciated.
Thank you in advance.
