• 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.

FS2004 Groundpoly bleed

Hi! I've a strage problem in my scenery. First of all I have a LWM flatten set to 69.8m which is the airport elevation. I created a 2x2 grid in Gmax, appliyed textures and tweaked (layer 8) as groundpoly. Loaded FS, all ok.

Then I created a rectangle as a roughly runway, exported and tweaked (layer 12). Now, when I load I see the first grid bleeding through the runway. All polygons are 0 elevation (z: 0 in gmax). I'm really going crazy as I cannot go thru this. Any hints? I need to put also an Area16 polygon or LWM should be enough?:confused:

Hi,

LWM flatten should be enough, area16 flattens are really old.

Thank you Arno. I removed the Area16 flatten and kept only the LWM one made by SBuilder9. All elevation's points are set to the same value (69.8m). I made several groundpoly and I never faced this problem.
As I said, the strange fact is that the bleed effects comes only when I have more than two objects (es: ground and runway, or grass and ground). If I leave only one model, all is ok.
I also tried to create a brand new polygon in gmax, tweaked and placed but the problem remains. The LWM flatten polygon cover the entire airport area, this means that runway, grass and ground polygon are inside my lwm.
Any hints? it could be up to the LWM itself?

I solved this issue by using a workaround: I've elevated all flatten models of 0.0125m above the surface and that strange effect disappeared. Btw it's strange, as I made several groundpoly and I've neved faced this kind of issue. I hope the trick I used won't bring me drawbacks... :rolleyes:

Just for information: the shimmering effect was due to the autogen suppression tweak I've implemented. In order to avoid that strage behavior, I had to set the ground layer's to 14.
