Like per download you get a fixed income, though I doubt this is the case but is there absolutely any benefit? For those who are going to wonder, no I started modding because it looked fun not for benefits
Not as provided by the developers, no. Though you could win modding competitions now and then. If people like your work you can always start a patreon and ask for donations, or start a modding/tutorial youtube channel and earn revenue from that. Generally speaking you can’t actually sell mods without developer permission, though they did just start a official mods program where they incorporate community made mods officially into the game. I assume the mod maker would get a sum of money for this, but I don’t know.
