• 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.

High Altitude Object Placement Solution.

Hi Everyone.

I'm having problems with object placement at high altitudes. More specifically the problem where objects I place at high altitudes are shifted from where I originally place them. I know the method of adding blank animations to stop it, but I want to know more about why these shifts happen.

My question to everyone, is there any logic to why the objects shift at high altitudes? Does the Latitude/Longitude and Altitude have an affect on what direction and how much the objects shift? Or is the high altitude shift problem a random thing? Has anyone worked out a formula that could work out how much offset and direction/angle to compensate for? I would love to work out a way that we could add in the coordinates and altitude of where the object needs to be and it works out the offset that is required to place the object in the correct location.

Cheers
Che

IIUC, the offsets are due to various factors, and leave scenery objects incorrectly placed for the progressive changes in FS' LOD / Quad Mesh ("Matrix") ID vertex grid interval size and Geographic coordinate position in 3D space with increasing altitude from the surface of the FS "ground", as well as not being corrected for the "curved Earth" shape of the FS 3D spheroid world model.

Thanks for the reply Garry!

The ground polys aren't shifted on mine too, which is fantastic, though I'll keep an eye on it.....things always go wrong.

I guess I'll have to manually correct the object placement, the airport isn't big so I guess the offset of an object at one end of the airport will be the same as the other end, thereabouts anyway. I will probably have to have different placement files for each version of Flight Sim too.
