I'm looking for the "model" folder, y'know, the folder that cointain the models of blocks. I'm coding for 1.18.1, can't find the folder, already searched for it in the assets.forge, but I can't find it at all. I've heard that there should be a folder called "assets.minecraft.models" but the stuff simply is not there. Searched for it, for half an hour, and I'm don't find it. Obs: "Don't know the .json codes, i'm new at modding(not exactly, but it's been a really looong time since the last time I coded )."
