Hi,
I noticed that quality raise the capacity but it seems not to change above 25k for me. Would be rly nice if thats working wit higher capacity.

Hi again,

I tested a bit locally and found this solution:

in control.lua

      --local mulP = mulP * (1+1*entity.quality.level) Removed quality effect on density
      --Added a quality effect on the capacity (game does this already because of prototype copy)
        local fluid_capacity = 25000 * (1 + (entity.quality and entity.quality.level or 0))

Changed max clamp from 5000000 * mulP to fluid_capacity * 200.0 * mulP:

    -- bound it just in case something crazy happened
    if target_energy < 0 then
      target_energy = 0
        elseif target_energy > fluid_capacity * 200.0 * mulP then
          target_energy = fluid_capacity * 200.0 * mulP
    end

Changed near-full clamp from fixed 24999.999/25000 to fluid_capacity - 0.001 / fluid_capacity:

        -- round it up if it's extremely close to full, to avoid floating point not-quite-full issues
        if new_level >= fluid_capacity - 0.001 then
          new_level = fluid_capacity
        end

If i understood it right now. I removed density quality effect on the fluid and instead allowed higher capacity.
