Sure, that'll take just a few minutes :р EDIT: Don't forget to change icon path to the full fishtank, because it's currently using the same icon as the empty one. Also, just saying, even though the full fish tank's weight is 35, the amount of water stored is nowhere near that. As in, it literally stores 4 bottles of water. item HCFishtankfull { IsWaterSource = TRUE, Weight = 35, CanStoreWater = TRUE, Type = Drainable, UseWhileEquipped = FALSE, UseDelta = 0.02641, DisplayName = Full Fish Tank, ReplaceOnDeplete = HCFishtank, ReplaceOnUseOn = WaterSource-HCFishtankfull, --> Icon = HCFishtank, ResizeWorldIcon = FALSE, }
