I have and Item/ItemStack and I need to get it's texture as an usual image. (I'm quite new to modding)
I tried doing random stuff with ResourceLocation, ItemRenderer and BlockRenderDispatcher, but didn't succeed. I know that now it's all models and not textures (and some other info), but I'm just too new to this to know what ways to do this exist
Can you help me?

Thanks, but I sill don't understand some details
I tried your way and created this:

Player p = Minecraft.getInstance().player;
Item item = p.getInventory().getSelected().getItem();
Block b = Block.byItem(item);
Minecraft.getInstance().getItemRenderer().getModel(item.getDefaultInstance(), p.getLevel(), p, 1).getQuads(b.defaultBlockState(), Direction.NORTH, new Random()).get(0).getSprite()

But what are the 4th argument in getModel(...) and 3rd argument in getQuads(...)? Am I using all of this in any supposed way? (I just don't know what to put in the arguments) Anyway, this (somehow) gives me the TextureAtlasSprite, but how can I save it to png file?
