I've been working through and old mod i made but never published and have an odd issue.  The mod adds about 11 custom planet types, which all work fine except with one visual aspect: the emissive texture maps for the planets work on some custom planets, but not others.  One new planet type's textures will work fine, but another's wont, swap them to replace another planet's textures and suddenly the do work.  I've checked file paths and names, i've tried the textures on planettypecustom01-20, works on some but not others. Textures that don't work on some custom planets will work fine if i replace say, raia's textures with them (as an example).  I'm stumped as to why this is happening.  Any ideas out there? Anyone had this happen before?

I just really don't get this.  Using the default PlanetRemapping.xml contents/files some custom planets show emissive textures fine, but when custom files are substituted, don't; and simultaneously some custom planets don't show emissive textures when using default PlanetRemapping.xml contents/files, but do when using custom files. Yet more never show emissive textures, default PlanetRemapping.xml contents/files or custom.  Is there some unwritten rule? Odd file formatting option? Do some custom planet prefabs just not work properly? 

Is there anyone left here at all? lol 

Ok now this is just ridiculous, I change ONLY the smoothness textures on one custom planet that's emissive textures DID work, and now the emissive textures DON'T work; and switching the smoothness textures back to the old ones does NOT resolve the issue. WTF is this...?

No one know? Or just dead forum?

Sorry, I'm usually the person to answer modding questions but the planet texture stuff was never really documented. The only help I can give you is to suggest you look at the modding example for planets or look at the Planet Type Eden mod.
