• 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.

Lastest development release package corrupt?

Hi Arno,
I just downloaded the latest development release and installed it.
MCX is no longer working on my system - it doesn't even start, no error message, nothing.

I noticed that the file size of ModelconverterX.exe is now 144 Kb and the previous version (which I had fortunately backed up) is 1,132 Kb.

Is the zip package corrupt?

Thanks
Gavin
 
Hi Galvin,

What OS are you running? The latest development release switched from .NET Framework 4.8 to .NET 8.0.

The exe is indeed smaller, but you should see a Model converterX.dll as well now. It might be worth to do a clean install as the structure of files has changed.
 
Hello everyone,

I have Arno's new MCX Development Release running now. But it did not happen without a minor snag. I assumed that since I was running Win 11 24H2 that I was updated on the .NET Framework. Not so fast buddy. I had version 7.0 on my machine because back in 2023 I had installed Visual Studio. So Windows doesn't necessarily keep it self updated on .NET Framework versions. So I updated my Visual Studio and along with it got .NET Framework 9.0. I'm sure you could install the .NET Framework by itself but I got myself a two for one by updating Visual Studio. The Visual Studio installer also warned me that my .NET Framework versions 7.0 and 6.0 which were installed on my machine were no longer supported. One last piece a advice. If you install .NET Framework 8.0 or newer you need to restart your machine for the new version to be loaded and active.

No need to install visual studio of course just to run MCX. On this page you can also download the .NET 8.0 redistributable directly:

dotnet.microsoft.com

Download .NET 8.0 (Linux, macOS, and Windows) | .NET

.NET 8.0 downloads for Linux, macOS, and Windows. .NET is a free, cross-platform, open-source developer platform for building many different types of applications.
dotnet.microsoft.com dotnet.microsoft.com

In MCX there is also a check for the .NET version, but that might not run correctly when the right version is not present.

Arno,

In my case MCX never started or ran without the correct version of the .NET Framework version installed, so consequently I never got a warning message.

Yes, the check is inside MCX, so I guess it only runs once the application gets started. Let me see if I can add a check in another way that does not require the application to start first.
 
I thought it may be related to .NET 8.0 and gladly found this thread. Somewhere I saw a link to the ModelconverterX forum, wich ended in a site not found page. Obviously it has not been updated. To my opinion, it is pretty hard to find help.
After installing .NET 8.0, which did not need a system restart, the actual development version starts again. Thanks Dan.

P.S. Next problem, can no longer drag and drop a .bgl file onto MCX to open. Via menu it works. Is there a setting somewhere?

Let me double check the drag and drop, that should still work.
 
Yep. The drag-n-drop isn't working for me either. Not for BGLs, XMLs, glTFs, ...
 
I can't reproduce that issue here, on my machine it works. I tried it both with the developmnent release that is online now and with my latest code. If I drag a file on the preview window it loads the object just fine. When I drag it on the EXE it also works.

Or are you dragging it in a different way?
 
Meanwhile I restarted the system and it works now.

It seems the installation of .NET 8.0 need a restart, to make this work. With the older version MCX 1.70 it was always possible so I guess this was a .NET problem.
 
I downloaded and checked the stable release, and drag'n'drop worked right away. So it was a problem with the development version.

I used Windows Explorer, and looked at the properties of the development version. Security tab. Then edited the permissions of my users to allow full control. Then drag'n'drop worked in the display window. Don't know why I had to do this on my computer. Works now.

Hi,
My bad - I'm running Win 10 but hadn't upgraded to NET 8.0.

I downloaded the NET 8.0 redistributable, installed, rebooted and now MCX works fine.
 
Glad to read most issues are fixed now.

I'll check if I can add a warning or something when the right .net version is missing.
