Well, I have two tgd files, each with a planet that I've worked on. I would like to import one planet into the other file to use it as a moon. In order to do this, I saved the planet's surfacing as a tgc and tried to import it into the other to file so I could attach it to a second planet object. However, the tgc is imported into the main node window instead the the upper level nodes of the second planet object. So all of my surfacing can't be connected to the planet it's meant for. Does this clear it up a bit?
