‘nonetype’ object has no attribute ‘name’ (Collada Export 2.49b)

The problem is related to the material assignments. Your Object refers to a material which actually does (no longer) exist in your blend file. It is unclear how this situation can happen. It may be an error in the Jass-Library (if you created your character from the character templates in it).

You can fix the problem as follows:

• go to object mode
• locate the material panel in the edit button section
• Remove all material indexes from the object by pressing the “delete” butto until The material index list contains “0 Mat 0″, see image on the right.
• go to the material section and add/create the materials you need.

Now you can retry the export. It should work now.
