• 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 Reduce flickering of ground polys

Is there any way of optimizing custom ground polys (especially taxiway lines etc) so that when viewed from afar/at an angle the flicker/aliasing is reduced/less noticeable? My own ground poly seem to flicker more easily than default and ADE ground polys. Is this because the textures are too opaque? Maybe have too much contrast?
Note: Ground polys made in blender, converted using ground poly tool in MCX

I've been working on including mipmaps and giving a little "full opacity gap" for the mipmap to blend with the base texture which have reduced it slightly but the flickering is still quite bad. Any other ideas?
 
The flickering is caused by the game engine trying to display what becomes at a distance a very small area of ground poly. Since you are using MCX GPW one of the things that you can do is control the distance that the GP is drawn by texture. The default is 10000 meters. You can make your line texture show at say 500 meters and this will reduce the flickering. In real life you really can't see the lines clearly as you taxi along until you are closer to them.

Maybe I was doing it wrong but I tried to reduce it assuming that it would determine what is visible based off of the viewer location. However, it was visible based off of the distance from the center of the GP. For example, if I was outside of the set radius from the center, none of the polys would be visible. I'm thinking instead of editing the ground poly textures so that the increasingly compressed mipmaps also have higher opacity but I don't know if that's how other developers do it.
 
Same issue for me, the line looks flickering from far. Minimaps on texture just reduce a little shimmering issue.
