I'm hoping someone can help me out. I've been trying to edit some cameos using the following steps:
extracting them using XCC mixer
convert them using OpenRA.Utility (and temperat.pal)
edit them
convert back to shp (again with OpenRA.Utility)
My problem is with step 4: "OpenRA.Utility --shp" doesn't take a 'palette' parameter, so I'm guessing the input png needs to already use the correct palette, but I'm kinda stumped as to how to do that.
It was my understanding that XCC mixer would be able to perform all these steps (except #3 of course), based on this post by raminator.
I also found the Open Source SHP Builder, which is nice enough, but it seems its shps aren't recognized by OpenRA as valid files.
