Unusable Grey Export, 0 draw calls on all exports

[chris-aeviator]

When using the latest blend4web addon (sdk) with blender v 2.7.6 (arch linux, blender-bin) I will get a grey preview & export html with zero content on anything I export.

An exported HTML file will always contain nothing, there are no errors logged to the browser's console.

I can run the example HTML files successfully, when opening the assosiated .blender files and running export/preview on them I will get the same grey result.

Installing the SDK within blender-2.8beta is not possible, it claims I'd need to update to blender-2.8.x

I'm new to blend4web and would really like to include it in upcoming development work and would appreciate any debugging help.

The same happens when running the project server via python3 scripts/project_server.py. When creating a new project (web UI), and building it, the standard logo cube seems like to be very far zoomed in as I am getting the following output:

I can drag & will see a slight change of white and blue.

EDIT: turns out that what I'm seeing is the sky
