The gp lines and gp surfaces in ADE can be displayed, but they disappear when imported into the P3DV5 version. What could be the reason?

hi all，The gp lines and gp surfaces in ADE can be displayed, but they disappear when imported into the P3DV5 version. What could be the reason?

Are you adding the CVX BGL file that ADE creates into an active scenery folder? It’s an extra BGL file.

Are you sure the required texture files are being added to the adjoining texture folder?

Also, if you changed P3Dv5.x's default airport elevation and re-compiled your project, you may have an _ALT BGL conflict to fix.


Download BGL2XML version 10.x and decompile any _ALT BGL ADE output for local ICAO's if altitude was changed from P3Dv5.x' default.

https://www.fsdeveloper.com/forum/threads/bgl2xml-gui-v-1-10.448225/


If ADE output a _ALT BGL for any local ICAO's, it / they will be located in:

[Prepar3D_v4_install-path]\Scenery\World\scenery\ sub-folder


Post the XML code BGL2XML outputs, within a reply here in this thread for local ICAO's if was altitude changed from P3Dv5.x' default.


IIUC, a search of your post history at FSDEV suggests you may be (rather secretively) working on one- or both- Shanghai city airports:

https://en.wikipedia.org/wiki/Shanghai_Pudong_International_Airport

https://en.wikipedia.org/wiki/Shanghai_Hongqiao_International_Airport


If that is so, please recall that you previously expressed an interest in flattening the entire city to (1) altitude.

P3D already does this for both airport flattens (Airport Bounds Polygon = "ABP") at Shanghai.

But if you did make a (1) altitude terrain flatten for the entire city, it might be in a custom CVX BGL separate from airfield ABP flattens.

ADE shows this altitude info in airport properties for those (2) P3Dv4.x default (aka 'stock') ICAOs ARPs and RWYs; ABP's should match:

ZSSS
Shanghai
Hongqiao
31.197777875,121.335555464
3.048 Meters

ZSPD
Shanghai
Pudong
31.141666733,121.789999902
3.048 Meters


ADE's status bar at the bottom of its GUI, tells us the info we need to find the P3Dv4.x default airport folder scenery path.


The P3Dv4.x default terrain-modifying flatten ABP for those (2) P3Dv4.x default (aka 'stock') ICAOs is in:

[Prepar3D_v4_install-path]\Scenery\1002\scenery\cvx8020.bgl


ADE lists Altitude assigned to any replacement ABP flatten for the (2) P3Dv4.x default (aka 'stock') ICAOs.


If you made replacement ABP flattens for those (2) P3Dv4.x default (aka 'stock') ICAOs, please tell us what the Altitude is for each one.

I have put everything in, but maybe it's because there is a landscape I created in my scene, and the two conflict, so it won't display?

Thanks, I'll give it a try.
