I've often wondered similarly for movies, especially CGI. So much time and money is spent to make complicated environments and intricate character models -- the end result gets preserved in the final cut, but what happens to the original assets? Do VFX studios typically maintain archives of past material, or does it all get wiped after each project? I'd think it would be handy to have for remasters, sequels, etc., even if they don't really care about preservation for preservation's sake. Physical props end up in museums or fetch a high price at auction from private collectors, but whither Avengers_Endgame_Thanos_final_final_FINAL.obj?
