Mass Per Liter

Weight reduction mod reduces the mass of fillers with the same capacity
Only works on stuffable items

The default coefficient is
g_currentMission.fillTypeManager.fillTypes[i].massPerLiter = g_currentMission.fillTypeManager.fillTypes[i].massPerLiter * 0.0005;
If you want to modify the multiplier later, you can make it smaller and lighter

Need to decompress!!!
