question Proper Way to import models into 0 AD?

[AGamer]

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:

See https://gitea.wildfiregames.com/0ad/0ad/wiki/ExportingErrors

Either you have loose vertices or multiple materials, and neither are supported.

Stan you did it again! Thanks for the help. I had multiple materials. 

When I removed them, I proceeded to have some model encoding issues which resolved when I deleted the constraints.

The error I was getting was:

XmlParseEntityRef:NoName

I know that is something to do with how Blender set up the XML data in the DAE itself, but idk. Deleting the constraints worked...

Anyway, thank you very much for your help, the model is showing up in game!!
