I need help changing the burn efficiency of the 423 CUI V8 Engine Offroad from the offroad Barstow mod without making the whole mod stop working //"burnEfficiency":0.26 "burnEfficiency":[ [0, 0.1], [0.05, 0.20], [0.4, 0.25], [0.7, 0.32], [1, 0.21], ],
That ^ is that from the default engine's materials.cs or jbeam? if it is the double slash means it's not used, which probably means it doesn't work, yet.
Where exactly are you stuck? Just adjust the numbers in that table? The commented part is old and superceded by the table version, however, it would still work.
