Exporting tracks from blender 2.80

[alex25]

i've been trying to export all objects from blender 2.80 into a jpk file but no objects get exported. if i export just one object to a joe file then it works fine. not quite sure what i'm doing wrong? i've tried selecting all objects, deselecting them all but still no objects get exported. i'm doing this on debian. any ideas?

looking at blender-scripts/blender28/vdrift.py at joe_pack.from_mesh() at line 367 i see

  objlist = bpy.context.scene.collection.objects

but it's empty so no wonder nothing gets exported.

thanks.
