Nick6794, if you're trying to remove Saturn's rings (which are not procedural rings), you must simply look for this line in the file SolarSys.sc (which is in CatalogsSE.pak):
// Rings texture author: Vladimir Romanyuk "SpaceEngineer"
and replace it with
If you made a planet but you didn't specifiy any rings and they just generated procedurally, just use this tag as well but you won't have to remove anything. Hope this was clear enough
