Are there any resources out there on modding Unreal Engine 4 games?

I know it’s relatively easy to decrypt the asset files and stuff, and maybe even to decompile the game, but then how would I get the edited stuff back into the game (and in a distributable way)?

Should I expect the game to be able to load the edited asset file without encryption alongside to the encrypted ones, since I probably wouldn’t be able to encrypt it with the same key as them, or nah?

I created this antispam mod for Minetest, and I hope it can be useful for the ones who run their own servers. Feel free to check it out: https://github.com/astra0081X/antispam.
I’d love to hear any feedback!
