I have never had a problem to export an animated file from Fragmotion or MilkShape into 3dgs but quite often the same file does not work if converted into FBX file format
Well, that is of course a problem sometimes. But it is a special pipeline problem between the used FBX version and the target software then. I would blame the target software here, or the app/plugin hat has written the FBX. Or even the chosen FBX format. There is more than one. And there are various settings too. But not FBX in general
Make it simple , this is a general rule
Milkshape is a bit too simple and limited for my flavour ...
