Is it legal and ok to use the GZDoom engine commercially, like putting a game/mod on steam?

like, how much of the code is legal to use for a commercial game/mod?


and if anybody knows, where could i get non-copyrighted textures and sprites for said game, too? i looked on Realm667 but it says i'd have to get permission from the creators but i have no idea how to contact them.


thanks! and sorry if this was the wrong place to ask.

All of the code in GZDoom itself is GPL-licensed and fine of use in commercial products.

You'll have a hard time finding anything for free. The vast majority of sprites and textures from the community are based on assets from Doom and other games and can't be used in commercial products. The only assets that can be used in commercial products are ones licensed under permissive licenses such as Creative Commons (except those with a Non-Commercial clause, which also can't be used in commercial products) and made from scratch. (or made from other permissively-licensed assets)
