• 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.

MCX Problem creating platform

Messages

Hi Arno, it's me who contacted Gary GB because my FS 2020 trains/simobjects are crossing solid bridges I created in MCX with an automatic platform on the deck ballast. So I downloaded the latest version of MCX, but I don't know how to use it to solve my problem. In the previous version, I could create a platform on the deck, and it was clearly marked in red in the correct place. In this version, it doesn't appear, and when I try to convert it, the fspackagetool opens but displays a red error message. I also tried setting "true" in the textures for "collision material" and "road material" (I don't see "ground material"?), but I get the same error message. Oddly enough, the bridge is sturdy when I land on it with a plane, but not for simobjects in FS 2024, whereas everything works correctly in FS 2020 (cars and trains). Pat.

Hi Pat,

Compared to earlier versions of ModelConverterX the platforms are no longer rendered as fully red polygons, they are now rendered as a red wireframe. So that can indeed make them a little less visible (but it is because in MSFS they are invisible materials as well and that is how I render those).

So in theory the way to create them has not changed. Did you make the platform manually or did you use the auto platform function?

The error that you posted does not look familiar to me. But let me try to add a platform to a model here on my machine and see if I can export it as a scenery package afterwards.
 
Hi,

I just tried to make a platform for a bridge here on my machine. My conclusion is:

  1. The rendering of the platforms in the preview is indeed not always very clear. That is something I need to improve.
  2. Exporting the bridge with platform to a MSFS 2020 package works fine.
  3. When I export as a MSFS 2024 package I do indeed also get the package_order_hint can not be empty error. It seems that line in the manifest.json should be package_order_hint": "CUSTOM_AIRPORT", instead of an empty string. Not sure why the fspackage tool writes it as an empty string. Maybe ModelConverterX should write some extra data to the project XML file that is packaged. I need to look into that.
 
For the last issue, I have found how I should write that information to the XML file. So I'll update the exporter for that.

 
I have implemented the change now so that when exporting as a MSFS scenery package ModelConverterX does set the package order hint attribute correctly. The change will be in the next development release.
 
A new build with the fix for the compile error is online now.
