When I first encounter this, I think the demo requires the directory under "rafx/demo-editor" which doesn't exist. Then i run demo-editor, some directors were generated, but the required "rafx/demo-editor/data/build-data/tog" is still missing. I don't know what to do. Thanks if there is clearer way to run this demo!
