Not sure about how you are re-creating the part nodes to the tree nodes (Probably just by that parts.cfg), so this may not even be feasible. My question then is it possible for your editor to have parts listed, by part 'name' to link to a tree node? Basically for mod support that would allow a tree creator, to cater for mods on a case by case basis, or leave them out if they are not there? In essence, a backwards link from tree -> part, rather than the other way around. If this ISNT possible, then as a suggestion, having some sort of 'editor' part for your program that can scan the part.cfg files, and 'insert' the tree nodes (again, on a case by case basis I guess) And with that, a sort of index file list could be distributed with a mod, or a tree (or both) that allows insertion into the career mode.
