I have 5 custom planets. Everything works great. But they look like billiard balls. 

I followed https://community.amplitude-studios.com/amplitude-studios/endless-space-2/forums/75-modding/threads/29329-modding-question-new-unique-planets?page=1

Yet I'm obviously not understanding something. I exported, replaced all the textures for CustomPlanet16, stuck the PlanetRemapping.xml in Public > Mapping, and... Nothing. No effect. I also tried remapping one of the vanilla planets to see if that would work, but absolutely nothing I have done has seemed to affect anything at all. Still, all my planets look like billiard balls. 

My mod works perfectly, everything is fantastic, but this one stupid thing is stopping me. I need help. Thanks in advance.
