• 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 and Mixamo animation

Good day Arno;
I run some tests with the latest mcx release; using mixamo animated characters; they fine if not loaded into mcx and saved again.
What happen if they are loaded into mcx even without any modification; saved; the compiler hang at the point it compile the gltf part; and there it stay.
An example of file is from Rhumbaflappy here https://drive.google.com/file/d/1WVBqv0PpCzqTmKQYJyfv1-eqJ5BAhlw4/view

Also if the lod is added and saved the compile do hang at the point it compile the first LOD00 gltf; basically something stop the files being compiled after being saved with mcx.
There are ways around it; but i wonder why this happen ? As it would be very useful to manipulate these kind of files in mcx in case of need. This is the MSFS 2024 sdk; I did not test in 2020.

for your time
 
Hi,

Do you mean that the MSFS packager tool has issues with the glTF files that ModelConverterX made? Do you get any warnings or errors in the log?

I am not really familiar with packiging something else than scenery projects, so I must say I never tried a SimObject like this.
 
Yes; if you save the gltf after download the mixamo fbx and converter with fbx2gltf; load the gltf into mcx and save it; sdk hang at the point it compile the gltf part; it just hang; no error showed.
 
OK, I'll see if I can reproduce it.
 
Hi,

I can reproduce the issue here. Now let me check what is different from other skin and bone animated models that don't have this issue.
 
I have done some analysis yesterday, but I don't fully understand it yet.

When I export the model the package tool gets stuck. If I remove all bones from the object it does export fine (in that case it still includes the weights to the model parts). If I remove the shirt and arms/legs modelparts I can export the entire model with all bones included.

So it seems there is some interaction between specific bones and specific model parts here. But I don't see any weird data yet.
 
Hi Arno;
is quite strange; as Mcx work with all other kind of rigged / animated objects; this is the only instance I come across. Having said all that; the first model I have converted; from Mixamo; I did use Mcx; and after push and pull; it did worked; I have to try to reproduce the steps and let you know. However; If i remember correctly the original model was from a different source; directly from ai; than the Rhumbaflappy model; I have to try to reproduce the steps and come back here if I find anything of help. My suspect is on the original model position / structure rather than anything else.
