Hey, long time lurker here. I had made a Serperior species addon for Starbound a few months ago, and had plans to make a Starpounds compatibility addon for it.
Which I did.
If anyone’s interested, I put it on Google Drive in case they want the same compatibility. It’s even got the combined state sprites, just throw the folder in your Starbound mods folder and it should work.
I might try and update the old Umbreon Big Fatties sprites someone else had made to be compatible with current Starpounds, too. Anyways, the title of this post doesn’t mean much if I don’t go from here and ask; Anyone else got species compatibility mods for Starpounds they’d be willing to share? Interested to see what people may have had cooked up!
