• 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.

Replaced Island doesn't show up

I recently replaced the entire default Island Set for Tangier Island with photoreal scenery. I've basically completed the project but noticed last evening that the landmass no longer shows up in "map" view or any other map utility. The airport ICAO shows up, but the Island itself does not. Since I removed the default, is it because there is no "landclass" attached to the new Island and if that's the case, how do I get the Island to show up again?
 
You need to create a hydro poly with a "hole" for your island. However, if there is a GPS hydro poly you may have further problems.

Nope, not what I'm talking about. In the sim, the Island is there. . .I've already finished the scenery as I stated in my initial post and I've been flying in and out of there for a week. What I mean is this. . . .if I pull up the "map" in flightsim. . .the Island doesn't show. . .the physical appearance of an Island is not there, only the ICAO code (which is loaded via the AFCAD).

Yes it is what you mean. The GPS display uses GPS Hydro Polys. If they are missing you won't see the island in map view.

Note. You cannot exclude GPS Hydro Polys, that was an omission on Aces part.
 
Hi George:

I was wondering if you might have encountered any additional information on what one should do when making scenery for this type of island scenario where both a GPS Map view and "3D rendered / in-flight" view are required / desired ? :o


By that I mean:

If we are able to successfully exclude and then re-make an island as a standard FSX compliant "in-flight visible" scenery as Ed did, is there another scenery BGL file we should also make (as a low-resolution GPS Hydro Poly )... perhaps even derived from our source data for the "visible" island, that is needed to provide a visual representation for the island in the GPS Map view ? :confused:


I haven't yet checked all other possible BGLs beyond those I originally referenced to the Lundy Island project in the linked thread posted for Ed above to see if UTX does this, but I speculate that may indeed be what they do in another BGL file aside from those used for standard "in-flight visible" scenery components.


If it is the case that another separate GPS Hydro Poly needs to be made in addition to the "visible" island, does the same construction process apply, so that with a different GUID for that "GPS" island being chosen, BGLComp simply compiles the low-resolution GPS version for us on the basis of a subroutine specific to that GPS Hydro Poly GUID in our SHP2VEC source file code ?

...Or must we create a separately rendered "low resolution" version of the shorelines etc. ourselves with new vertices before feeding the data to SHP2VEC ?

Just wondering what we might do in such situations. :rolleyes:


PS: In relation to the "partially non-excludable GPS Hydro Poly" in your above cited Lundy Island project, I was wondering if one can simply "cover up" non-excludable "GPS" islands made of GPS Hydro Poly GUID coded BGLs by creating another replacement "GPS" island placed in an "opaque" layer higher in the FSX Scenery Library ?

Conceptually this would be like placing textures on top of textures so that the topmost is what is seen in the GPS map "top down" view... comparable to what we can do with textured ground polys covering up custom photoreal ground textures if they are placed a fraction of a foot or meter (ex: 0.125) above to minimize Z-Buffer fighting in standard "in-flight visible" scenery.

Oh, and what would be the difference in methodology required (if any) to accommodate a GPS Hydro Poly while also having properly blend masked custom land class photoreal textures for the "in-flight visible" portion of the scenery such as Ed may have done above, instead of using default land class vector polys (ex: created via FSX-KML or SBuilderX) ?


Thanks very much for sharing any additional insights you might have on this. :)

No, I have given up trying to get an island to display in map view.
 
Hi George:

Can't blame you for being frustrated with the apparent limitations in FSX with GPS Hydro Polys; but being a "preferentially irrepressible" sort, I was wondering if some workaround might still be achievable in FSX via another method that is not too cumbersome where both a GPS Map view and "3D rendered / in-flight" view are required / desired ? :p


Ed and Lance's discussion answered part of my questions posed above, and (characteristically... of course!) triggered some further "wondering" on my part regarding some possibilities in the thread linked below; perhaps this might be of some interest in your work with islands in the future ? :rolleyes:
