Wonderful SteinerX. Now two things, first, the button files should be in tga, not dds. Second, I've added psd into your icon directory. Please take a look at the included button effects and tell me what you think of them.
About the brushes file, You could add the pictures to the tga file I used for the Jumpgate Icon and edit the relevant brushes file. That would be the easiest way. or, if you insist we can make a completely new brushes file for you.
And I put a few pictures of the ships into the icon folder. Especially take a look at the troligan, this would be my preferred version for ingame usage.
Put the relevant tga and the brush files into the icon directory. You need to convert the brush to txt and then edit it and convert to bin again for ingame use (same as with the loadscreen brush). If You want me to convert it to txt for you, just tell me! Can`t do it atm because I'm at work
Yes, other races will be added when the time comes. I opt for having 2 races (minbari, ea) mostly finished first so we can leave prealpha then.
Edit: Yep, Welcome back ZEROibis, we were missing you!
