Hey, I was trying to import a model from a different game into 0 AD. I joined all of the mesh parts together, scaled it to the 0 AD armature, weight painted, and then exported to Collada. First error I ran into was the "Multiple Polysets" error. To remedy this, I clicked on the mesh and then selected export selected only. Then I got a "No Objects in Scene" error.  I am wondering if I did something wrong or formatted it incorrectly. I know that you are supposed to remove the light and camera from the scene, but anything else, I have no idea... I would really appreciate some help from you guys    Here is the scene for reference:

Can you test since I gave you some extra rights ?

No, pointing to my fork. Pushing did not work while configured to the main repository. I did try first without changing the config, to test if the gitea update changed something and after that i changed the setting and did the same commands again. 

Was it still pointing to 0ad/0ad ?

Oh nice  i already tested it before u added me ,  the git lfs pull 0ad-base main worked without errors. (unix fashion no complaint is all right)
