Im doing this for American conquest.
I think its the bmps too because when I use megapack to pack them to Gps then when I view them all I get is a black screen. Nothing else. Although it does tell me my frame numbers and acts like it wants to work, it doesn't show anything. Also when I press zoom it doesn't show I zoomed in the 100% thing if that tells you anything.
The frames im using are 24bit.
The weird thing is that I used a bitmap of a tank sprite from the old game WestFront and packed it to gp. I could see it in the Gpviewer but with disfigured colors (dark, grey). I was like ok that worked, but why are my bmps not working?
So I copied and pasted my sprite over the WestFront sprite. I packed it and I saw the tank with a silhouette of my soldier over the tank . My sprite though was alpha colors.
I followed everything in the readme and I can successfully pack (repack) AC gp files.
Here are some Im using. They are rough though!
Here is the West front image that kinda worked.
I also think its the colors?
Edit: Doing more tests.

Ah I dont know what it is. I tried 8 bit 16 bit 24 bit depth bmps. Everyone I try I get nothing in the gp viewer. Just black. Maybe. . . ....
