could you add an steam icon tgo the barrel? right now it is not different from the empty barrel

When I put the empties and steam barrels next to each other I can differentiate them. Maybe your monitor?

I'll see if I can make the barrel a brighter white. For now I'm trying to keep it looking like the other non-descript vanilla barrels already in the game.

But I'm open to making the barrels bigger.

You're right, they are different, I was using Fnei, and they looked pretty similar, but they are not

I'll check using FNEI.
I still have the issue of the different steam barrels all looking the same.
