Hi, why in the OP Center i don't see the aircraft specific settings?

 

I use P3D 3.2 and the latest version of PMDG 777

 

thanks

Is this a newly installed livery?  If so, there might not be an ini file until you load the aircraft, make a change in the FMC-based options for the aircraft.  Now there is an ini file and the OC will behave as expected.

I sometimes download liveries and no ini file gets installed, the repainter I think is at fault for not including one in the package - David Lee
