• 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 groundpoly weather issue?

Now that I've solved my mipmap problems I run into another problem (see image):

My ground consists of a combination of a 3D model (because of slope) and a small part of a 2002 ground poly (easily spotted in the image) because the PAPI there would vanish behind the 3D model.
Now, both work perfectly together, but only with fair weather. If I use lower visibility settings I get the effect you see in the image. When I get closer to the errand area, the effect vanishes and the shading is perfect again :eek: - the same occurs if I fly backwards.
As this effect also only occurse if I look in this direction (which is away from the refpoint) I wonder if it's got to do with refpoints. Has anybody ever experienced a problem with wrong 2002-groundpoly shading under certain visibility settings if the user is between the errand part of the groundpoly and its refpoint?

A bit tricky, I know, but I'm really lost again. :o

Hi Thorsten,

Do both parts have the same reference point?

I have seen weird effects with FS2002 ground polygons before, because the shading of each tile is determined by the distance to its reference point. So that can give different shading in different tiles at lower visibilities.
 
I had similar problems when I was using Ground Poly's for my imagery. The first time I looked at the scenery in low visiblity, the fogging was all messed up.

In the end, I decided to use the FSX native photoscenery technique instead, and now the quality is 10x as good, and there are no issues at low visibility.

As far as the PAPI disappearing, just make one from scratch using the separation plane technique and you won't have to worry about it getting clipped.
 
Unfortunately I already use tweaked BGL-Lights for the PAPI, but as the ground is an FSX 3D mdl the PAPI vanishes, no matter how it's created.

I think I'll try another refpoint (within the area).
