Step 2: Export Your Model to XML
Once you have a model you would like to use in Blender open Edit Mode and hit the "a" key to select all points. In the bottom panel select text editor.
Open a new file in the text editor. Open the blend2java.py file that you downloaded. Run.
Ok your object should now be in .XML wherever you saved it (if you have and error message make shure you only have 1 material for the object). Rename the object (it will have a weird name).
