With this Code you can show which Fluid is inside ^^

{ { icon = "base/graphics/icons/storage-tank.png", tint = { r = 1, g = 1, b = 1, a = 1 } }, { icon = v.icon, tint = { r = 1, g = 1, b = 1, a = 0.85 } } },

Have fun with it :P

Thank you, LuziferSenpai! I was going to look into icon generator as soon as I finish the initial mod fixes. I've looked into Omnibarrels' code to figure out how to work with icons, and now you've posted some info too, so it shouldn't be a problem. I really want to use a mask or two to make the icon more readable, I think it's pretty easy to do too.

Look in my Straight Pipes MODS, there I use it too ^^
