I assume you have read the basics on packing with mega pack?

It depends a bit for which game you are doing this? Cossacks or American Conquest?

But my gutfeeling says it may be something with the frames itself. Are they 8bit, 16 bit,..?

Could you write down the exact procedure you followed?

I'll see if I can help then.

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!

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. . . ....

edit: It was the background color that made it work. The stugh I used had a white background and it showed up with bad colors. The others I was trying to use had black backgrounds and didnt work at all. I guess that's why it didn't work. Interesting.
