I thoroughly sympathize. I have a substantial aversion to playing games with a wiki. As a player, I do not like having to guess whether game content is something I am supposed to look up online, or figure out in the game. If the former, creators should just put the information in the game, even if it is nothing more than an inelegant text file. And I often feel that, if I am just going to follow an online guide, I might as well skip installing the game and just watch a playthrough on YouTube.

MeshMixer is the program I use for a lot of mesh editing. It has a nice set of features, but feature development was ended in 2021, so there may be more modern options available.
