SOLVED:
My file was 1024x1024, which meant that it only showed the corner of the file. I fixed it by downscaling.
data.lua file:
Code: Select all
require ("prototypes.liquids")Code: Select all
data:extend({
    {
        type = "fluid",
        name = "oxygen",
        subgroup = "fluid",
        default_temperature  = "0",
        base_color = { r = 139 / 255, g = 139 / 255, b = 139 / 255 },
        flow_color = { r = 139 / 255, g = 139 / 255, b = 139 / 255 },
        icon = "__petrochem-revamp__/graphics/icons/fluids/molecule-oxygen.png",
        icon_size = 64,
        icon_mipmaps = 4,
        order = "b"
    },
})
