• 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.

FSXA Ground Polygon Texture disappears at long distance

Hello:

I have some ground polygons with textures, all the textures have mip maps.
The problem that I have is the at long distance the polygon texture disappears and I can see the default ground.

Is there a way or method to solve this issue?

Hi,

In the Ground Polygon Wizard it says layering and visibility. Does that not work for you???
 
I have the concrete polygon with a visibility of 10km and layer=16.

If I use a texture without mip maps the texture doesn't disappear at long distance.

Regards
 
The problem was that I had created the Texture with DXT1 Format. I changed to DXT3 format and the bitmaps were created well. I can see my polygon textures at long distance.
For ground polygons use DXT3 texture instead of DXT1 textures.

Interesting that one apparently can limit or improve FS object visibility distance via choice of BMP texture file DXT-type: :idea:

BTW: While the OP's above reported maximum visibility distance for the OP's Ground Polygons (10 Kilometers = 5.399555 Nautical Miles) is slightly different than that of the reported maximum visibility distance for ex: Autogen 'Tree' objects, it is also remarkably 'close', and it raises questions (for me, at least) about whether / how texture format plays a role in the way the FS rendering engine may control "autogen fade-in / fade-out" as implemented in FS2Kx (...or P3d ?). :scratchch


Interested readers may wish to see this 'worked example' in a FS world globe terrain grid location quad size at 41°08′19.88″N

http://www.fsdeveloper.com/forum/threads/autogen-radius.81821/#post-233623


9.25 LOD-13 quad tiles x 1223 Meters (avg.) span per quad tile = 11,312.75 Meters

11,312.75 Meters = 11.31275 Kilometers or 6.108396 Nautical Miles "autogen object visibility distance"

[EDITED]

NOTE: For more info regarding the position on the FS 3D world globe where reported size / aspect ratio of MSFS terrain grid Quads / Area Points may be closest to equiangular quadrilaterals in configuration ...see:

[END_EDIT]


Thanks for sharing your work-flow and troubleshooting as you develop your project; it may help with better understanding how the FS SDK operates in those areas which are (still) under-documented and less well understood. :)
