So, everyone using the new JustFlight Piper Arrow III with this mod and having issues with the bezel of the GNS530/GNS430 covering some pixels, here’s the fix:
Navigate to the file in your Community folder, copy it somewhere as backup.
Then open the file in a text editor:
justflight-aircraft-pa28-arrow-iii\SimObjects\Airplanes\JF_PA28_Arrow\panel\panel.cfg
Find this block (this is from the original file):
[VCockpit05]
size_mm = 350,190
pixel_size = 350,190
texture = $SCREEN_GNS430
htmlgauge00=NavSystems/GPS/AS430/AS430.html, 0, 0, 350, 190
[VCockpit06]
size_mm = 320,234
pixel_size = 320,234
texture = $SCREEN_GNS530
htmlgauge00=NavSystems/GPS/AS530/AS530.html, 0, 0, 320,234
And replace it with the following:
[VCockpit05]
size_mm = 350,190
pixel_size = 350,190
texture = $SCREEN_GNS430
htmlgauge00=NavSystems/GPS/AS430/AS430.html, 4, 3, 342, 183
[VCockpit06]
size_mm = 320,234
pixel_size = 320,234
texture = $SCREEN_GNS530
htmlgauge00=NavSystems/GPS/AS530/AS530.html, 4, 3, 316, 231
Save the file and restart the sim to see the effect.
Here’s my original post about the “before” state:
And here’s how it looks after the fix:
@LikelyMatt you asked to be notified
