Hi,

"AttributeError: 'Context' object has no attribute 'depsgraph'

location: :-1"

Just FYI

@happyrobot that add-on is not maintained by the Blender project, the author will need to update it.

@RaduCoc, somehow you have installed the OBJ add-on, rather than using the one that comes with Blender. So you're running an outdated version. It's not clear how you go into that state, but you should remove this folder:

C:\Users\Alex\AppData\Roaming\Blender Foundation\Blender\2.80\scripts\addons\io_scene_obj

I work on the exporter for BabylonJS. It is (or was fully updated for 2.80). I refreshed my Blender yesterday ( windows 64 bit), and I get the same issue. Do not think this should be closed unless the api has changed for getting a depsgraph someplace other than the context.

After running GLTF successfully & looking at their source, they were not passing a desgraph in to_mesh(). Checked API, there are now no args to to_mesh().

Took out mine & it now runs, but there was also an arg to get modifiers applied. Is this happening?

Downloaded the latest 2.80 Beta Windows 64 bit build from today, May 22, 01:38:00 - 0f98c05c8b

The problem still persist. Seems that has something to do with depsgraph:

depsgraph = context.depsgraph
AttributeError: 'Context' object has no attribute 'depsgraph'

Works well now, needed to delete all .config directories and made a fresh install of Blender.
