This might be more what we're looking for. Spring is more updated and from what I've seen has more open code and steady development, but is hampered more as it's like StarCraft - The map engine is rather lackluster. I'll download the 2100 code/engine and take a look.
Just looking at the forums, it seems we may run into the same issue with polycount we had with MC2/MCO. Also, Warzone doesn't support DDS, but appears to just support PNG (I'll make an account and hound the developers about all this, in a day or two.) PNG is awesome, but runs into the same problem with TGA. They're big files (though not as large as Targas) and that means more graphics memory. Another issues is the models seem to be in a ".pie" format. I found a model importer, but I'll need to find out how animations are done, first. I don't want to get stuck in the same position I was previously, where I really couldn't add anything, other than textures, due to the fact I couldn't use the tools I'm familiar with.
