Weird looking engine

[cyclops365 0]

Hi

So I flew a flight today and noticed the inside of my engine looking like this. I'm pretty sure after using the PMDG 737 for a month it hasn't looked like this until now...

Is there a way to get this back to the way it was?

Thanks

I believe this is a common issue if you load the NGX, then switch to a different aircraft.  For example, load the NGX, then switch to a different livery.  The manual says this is a no no for that very reason, it can cause faults.  When you restart the sim, it will be back to normal.  Remember to only load 1 PMDG aircraft at a time.  Don't switch liveries once the aircraft is loaded without a restart of the sim.

Brilliant, Seems like that's the answer. Cheers
