When you say it is incompatible with OPM are you referring to Outer Planets mod? And is it because the planets would be too close to each other? im just looking to add as many planets as I can to my awesome gameplay! so far.. multiple star systems wouldn't work with OPM apparently as far as I can tell or I just did it wrong... nobody in these communities seems to do video tutorials the way minecraft modders do.
