Ther are two image texture names for the cockpit, one is for the dash and the other is for the cage, each one needs it's own set of images to do the whole cockpit. It is not necessary to do both the dash and cage, you may just do one or the other.
You will need 5 images for each texture.
One at 256x256, 128x128, 64x64, 32x32 and 16x16. The name of each image should end with the numbers one thru
five. All the images must be in the same folder. Then open the Hudpatcher click "create custom tek file", select the folder that contains your cockpit texture, choose a name for your Tek file and wa-la you now have have made a cockpit texture tek file. I hope this explains it well enough, I'm not that good at writing instructions
Example:
cage1.tga
cage2.tga
cage3.tga
cage4.tga
cage5.tga
cdash1.tga
cdash2.tga
cdash3.tga
cdash4.tga
cdash5.tga
