Hello guys,
I'm finally finished with the command center, anims and everything!The anims are a little weird, however, I'm not exactly sure why, but the ring has some problems rotating, I'm gonna be posting a question on the Blender help forum about it later.
...
Also I fixed the texture of the medium infantry, too.
I found that my version of photoshop has some trouble exporting the targa, so after installing GIMP, I used it to export the targas, and it turn out with the alpha. w00t!
Please let me know what you think.
