Okay, if I make a project with 3DGS and I upgrade to Pro before distributing it, how hard is it for the end-user to make use of anything they might build if I distribute the World Editor with the finished game?

I mean in the project, I have buildings - a different building for each different level - and these buildings use the names of textures to identify which part of the building it is, e.g. window, door, eaves, roof, etc...

Even if I can successfully train the end-user to correctly name the buildings that they build, how can their building be incorporated into the main game? Currently, each building I make for the game gets a little icon (button) that the user can select to start that level. How can I code the game to use the user's buildings?

I would appreciate any of your input on this topic, regardless of how small a tip it would be. Other ideas for how to do this are also welcome.
