• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FSX New islands not showing on GPS map

I used SBX to create some islands that exist in real life but are not present in FSX. That worked fine but I noticed that when I look in the a/c GPS (standard GPS device) these new islands are not showing, all I see is water...

How can I have these new islands appear on the GPS as well?
 
Nope, I haven't but isn't that to show water? I need to show the islands rather than the (excesive) water. Or am I misunderstanding what a GPS_Hydro_Poly is?
 
GPS water is a separate item within FSX than "regular" water. You excluded the regular water, correct? So how are your islands to show if you haven't excluded the default GPS water and added revised GPS water?

You *should* be able to copy and paste your new water data and then change the TAG to reflect it's for the GPS.
 
So basically I need two things:

1. Copy my Water current Exclude_All_Terrain_Items polygon and mark it Exclude_All_Water_Polygons_GPS ?

2. Copy my QMID 11 Water Polygon and tag it GPS_Hydro_Polygon, right?

And... if I have a GPS Hydro Polygon, do I also need to copy all the polygon "holes" (the islands) and select the GPS_Hydro_Polygon as their parent? or can I leave it as is? Please confirm.

I have never done a SBX polygon copy, mainly because once it is place (right after the copy) it becomes very difficult to edit it, you don't know whether you are clicking on the copy or the original and then the whole thing moves and the project is screwed up. Would have been nice to have finer control of layers.

BTW Selecting a polygon I see it is selected but the Edit|Copy menu item is greyed out in spite of the selection. Problem there also being as I said, once you place it there is no way to tag one of them because you can view either ALL excludes or none, I see no option to select your polygons or lines from a list to perform this kind of operation. For excludes it is not so much of a problem because one can make it a different shape (no need to copy) but for other polygons (water) you want to preserve the coast without having to do that detailed redrawing again.

I've never done GPS water revisions and appreciate you being the "beta tester". :D It *should* work like any other terrain addition/deletion.

You can try the Windows standard Ctrl-C and Ctrl-V for making a copy. Note you need to be using the "Poly cursor" mode when copying and pasting through the menus, IIRC?

When making a duplicate poly I will offset it slightly until I am satisfied that things are doing what I want, then will go back and zoom in real close to position the poly for final compile.

Click to expand...

What you can do is for example, delete everything from your project except the water polygons, tag them as GPS hydro polygons, then export that to a new file as "SBuilder SBX". Then you could re-open your project and use "Append > SBuilder SBX" to import the GPS polys into the project at the last minute before you select all lines and polys for export to .bgl.

I keep SBXs of every part of my project, one for the hydro polys, one for the shorelines, another for hydro poly excludes, and one for shoreline excludes. etc. This has come in very handy as a backup measure, but it can also be useful for merging projects. I don't have any excludes (shoreline or water poly) in my actual project because like you mentioned, it's impossible to work with duplicate polygons that occupy the same area. I import the exclude SBXs into the project just before I export it to the sim, then close without saving so the exclude polys don't get saved into the project.

Great ideas guys! So far I have been having only two SBPs, one for the landclasses and the other for polygons, lines & objects.

I keep my water and land polygons together because I can see how closely matched they are (no or very little gaps) and edit accordingly. However, for the GPS Hydro Polygons it seems I should just create a separate SBP for that.
 
But .SPBs and .SBXs aren't the same thing. You can export and append an .SBX which means you can open your water polys file and import (append) polys or lines exported from another file. Check out the "File > Append" and "File > Export" options in SBuilderX. It's a bit like gmax, where you can merge parts of one gmax file into another scene.

The GPS code is totally screwed.

I created separate files containing:

1. Hydro-poly only



2. GPS-Poly only



3. Both GPS and Hydro polys




The results in FSX were surprising:

1. With the GPS-Poly only, nothing was displayed in FSX or the GPs.

2. With the Hydro-poly only, an "H" was displayed in FSX but nothing on the GPS.



3. With both thr GPS and hydro-polys, A "G" was displayed in FSX :eek: but again, nothing on the GPS.
