Hi dobin.

Yes there is more changes needed. I should have mentioned that you must make modifications to the panel.cfg too. No one asked so I assumed they knew. I should know better. :-/

First backup the original panel.cfg. Then you need to edit all the gauge entries that are in another panel folder.

Like this one from the CS_B52 panel.cfg:

[Window04] <-- 2D panel
file_1024=..\..\b747_400\panel\ECU_Background_1024.bmp <- location of the background image used
size_mm=404,366
position=7
windowsize_ratio=0.8
visible=0
update_rate=6
ident=THROTTLE_PANEL
gauge00=..\..\b747_400\panel\Boeing747-400!Throttle Quadrant, 0, 0

The =..\..\ takes you to the FSX\SimObjects\Airplanes folder, then the b747_400\panel\ takes you to the default FS 747 panel folder (I guess you might have figured this). The default FS 747 panel folder is in the folder where you find all the background images and gauges which you need to use.

[VCockpit01] <- VC panel
size_mm=512,512
pixel_size=512,512
texture=$747_1
background_color=0,0,0
gauge00=..\..\b747_400\panel\Boeing747-400!Standby Altimeter, 0, 113, 111, 101
gauge01=..\..\b747_400\panel\Boeing747-400!Standby Airspeed Indicator, 112, 114, 111, 110
gauge02=..\..\b747_400\panel\Boeing747-400!Standby Attitude Indicator, 113, 1, 111, 111
gauge03=..\..\b747_400\panel\Boeing747-400!Primary Flight Display, 6, 234, 243, 267
gauge04=..\..\b747_400\panel\Boeing747-400!Multi-Function Display, 286, 259, 224, 252
gauge05=..\..\b747_400\panel\Boeing747-400!Clock, 1, 1, 113, 113
gauge06=..\..\b747_400\panel\Boeing747-400!EICAS Display, 286, 2, 224, 252
gauge07=Magnetic_Compass!Magnetic-Compass,225, 166, 60, 59
gauge08=..\..\b747_400\panel\Boeing747-400!Autopilot IAS-Mach Window, 233, 0, 45, 15
gauge09=..\..\b747_400\panel\Boeing747-400!Autopilot VS Window, 226, 15, 59, 16
gauge10=..\..\b747_400\panel\Boeing747-400!Autopilot Heading Window, 233, 31, 45, 15
gauge11=..\..\b747_400\panel\Boeing747-400!Autopilot Altitude Window, 226, 47, 59, 16
gauge12=..\..\b747_400\panel\Boeing747-400!Autopilot Hdg Switch, 259, 253, 25, 29
gauge13=..\..\b747_400\panel\Boeing747-400!Autopilot Localizer Switch, 256, 64, 29, 30
gauge14=..\..\b747_400\panel\Boeing747-400!Autopilot Approach Switch, 226, 96, 29, 29
gauge15=..\..\b747_400\panel\Boeing747-400!Autopilot VS Switch,256, 96, 29, 29
gauge16=..\..\b747_400\panel\Boeing747-400!Autopilot Nav Switch, 226, 126, 29, 29
gauge17=..\..\b747_400\panel\Boeing747-400!Autopilot IAS-Mach Switch, 256, 126, 29, 30
gauge18=..\..\b747_400\panel\Boeing747-400!Autopilot Speed Switch, 257, 285, 29, 29
gauge19=..\..\b747_400\panel\Boeing747-400!Autopilot Altitude Hold Switch, 226, 64, 29, 30
gauge20=..\..\b747_400\panel\Boeing747-400!Autopilot Master Switch, 259, 227, 25, 24
gauge21=Captain_Sim.b520.icon!iExit, 0,0, 2,2 <- this entry means the gauge is in the same folder as the panel.cfg OR the FSX\GAUGES folder

If you are unsure how to do it. Let me know which aircraft you are wanting to use the VC from, I will do my best to show you exactly what those changes need to be.

Hope this helps.
