When your vehicle is finished and you want to save it as a "UPD" version, follow these steps with AdvDupe2 : Steam Workshop::[ACF] Armored Combat Framework

Place the .txt dupe files directly into this folder or a subfolder.

ACF vehicles are complex "contraptions" that replace standard Source engine physics with realistic drivetrain simulations.

-- Assuming acfVehicle is the table representing your ACF vehicle function DeepCopy(tbl, seen) if seen == nil then seen = {} end local copy = {} for k, v in pairs(tbl) do seen[k] = seen[k] or {} if type(v) == "table" then copy[k] = DeepCopy(v, seen[k]) else copy[k] = v end end return copy end
