Is there a way to reverse rotation by using blend4web_17_06 addon?Yes, see This Post above to find the code.
Also, I just read this Blog post about 2.79
At the end it says:
Blend4Web is already fully compatible with Blender 2.79!I saw no console errors in the HTML file you attached. So there is some difference in your Blender install and mine since I exported it just fine from the same .blend file.
I am going to download 2.79 and test it out.
