Thanks Carver413...I have already looked there and not much joy on the sprite side I'm afraid

I DID find these blender models here:
http://opengameart.org/content/blend...-freeciv-units

Maybe I could take some 2d side view shots of the submarine and ship models in blender as sprites, but I can't figure out how to do this even after reading the manual

But then I do like my submarine sprites already and they wouldn't match those...
