I have a bunch of models I converted for use in space engine. They were all created by third parties, some of them now defunct, as third party consumer addons for M$ Flight Simulator. Since I am considering releasing them as part of my TPE Universe, how do I go about respecting copyright laws when doing so? Specifically, the models are theirs, and the textures are both theirs and mine, since these models were released as paint kits, so fourth parties could modify the textures and (re-)release at will given proper crediting.
As for proper crediting, how do I do that part to begin with?
