I've been having trouble for months now with uploading a rigged outfit.
From what I can tell, the model seems properly rigged in Blender (3.3.1, made in blender 2.8ish). But upon uploading to Second Life (Firestorm), the model is completely invisible.
Ticking off the "Weights" option makes the model appear, but that's not terribly helpful.
I'm not at all sure what to fix here. The best lead I have is that years ago I uploaded a model with an older version of blender (I think 2.79?) and it worked. And uploading that model in a more modern version of blender doesn't let it upload. Vice versa, putting my current outfit in an older version of blender won't let it upload.
And while I could theoretically re-make the entire outfit in an older version of blender, that would be incredibly painful, as well as not even guaranteed to work.
Regardless, any help in getting this mesh to upload would be appreciated.
