• 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.

MSFS20 Airport Ground Poly That Follows MSFS DEM Model

Hi all,

I've created a ground poly in Blender, and successfully exported as glTF and put inside the sim. However since the ground poly is flat, at some places it penetrates the ground. In P3D we can use MCX Ground Poly Wizard and it will convert everything to follow earth curvature inside sim. But for now it can only export as P3D BGL. I've also read some posts about projected mesh and its texture quality problems. Any idea how to create 3D ground mesh? Should I edit the model inside Blender and download some DEM model to be imported, so when I export the model is already in 3D. But I believe that's a hard thing to do. Or is there any external tools/addons that can convert everything? Still wondering how those payware addons managed to design 3D ground poly, sloped in X and Y direction with crisp texture. Thanks!

Projected mesh is crisp enough for large scale objects. Smaller details can be made with plain 3d objects put above the main mesh at a very small elevation to avoid penetrating the ground or z-fighting. You can also use native aprons with custom materials. For now there is no analogue of FSX/P3D style ground polys AFAIK.
 
But I'm still wondering how payware devs managed to create crisp ground poly, because I think they're not using built in aprons by wandering around in dev camera. Or are they?

Why not? They possibly use custom materials for the aprons, but otherwise you can do everything you need with them alone.
 
Skidmarks made with pure projected mesh:

To me it looks crisp enough.
 
Skidmarks to the left of the plane's nose are imported as scenery, to the right - as projected mesh. Can you spot any difference?

Skidmarks with white markings, again projected mesh. No problems with crispness whatsoever:

Nice! The texture is crisp enough from those pics. I'll try using projected mesh for now. Thanks!
