Well, I tried a few more things, but no luck. I need someone who does modeling to paste a working MFD screen object from a different helicopter into the Havoc HAVOC_VIRTUAL_COCKPIT_INSTRUMENT_NEEDLES.ees file right over the engine gauges, then save it. Send me the ees or lws file and the name of the MFD object you pasted in (and the texture name if you know what it is) then I can fix the Havoc engine gauges. I don't think it will work any other way.
I can send you the NEEDLES.lws file if you tell me where to send it via a PM.
I think I'll go work on something else for a while.
