@ThePortuguesePlayer I looked into the issue and it's because of the order of the objects in the Blender scene. The glass material will see through any objects that are below...
Also to answer this question, > Is it possible for the exporter to order the objects and materials considering alpha usage to see if that fixes this bug? No it...
If you want to keep the same name, you can try this: rename the object, duplicate it, delete original model and then rename the duplicated model to what it was...
You need to apply transformation for your object(s). Press ctrl+a with them selected and choose all transformations.
No idea what you mean by 'upside-down'. Also yes, that's intentional. They take the name of the collection because you can have multiple spheres/meshes in the same collision model.
Is it just the name for the UV map or is there anything else wrong?
I don't think the issue mentioned above is the reason for the crash. It's more likely that the exported col file had the wrong name.
This issue is fixed in the typing branch
@FlorinPT No
:facepalm: Might as well just use a different file format to remove the limitation, right? Like I said, you CANNOT remove this limitation. It will not be a DFF file...
