Yes, that can be complex to establish a list with all blueprints used for someone who have done a great project without a specific plan on this aspect ![]()
About the mention of blueprints authors, I think its mainly a question of respect of other’s peoples work, but he can solve this by a simple list in the shared world thread, no need to make something complex or too detailed. Something like this should be enough, and even better with the links to the blueprints threads:
“ Thanks to the following authors for their blueprints used in my world :
- Author 1 for Blueprints 1 & 2
- Author 2 for Blueprint 3
- …”
And about the risk of blueprints being stolen, yes, it's always possible, but all authors take this risk when publishing, regardless of the field. Here, it would just be a bad behavior without major consequences. There's no money at stake, just a bit of reputation in a community of players, so something quite secondary for most authors.
