Fast Preview button not showing

Hi,

I installed blender and blend4web addon on.
I could see proper json/html export option on file->export tab.
However, I cannot find "Fast Preview" button on the bottom tab.
Could you please let me know what went wrong?

Regards,
Justin

Hello!
What is your operating system?
Could you show a screenshot of Blend4Web addons settings? (File->User Preferences->Addons Tab->Blend4Web Panel)
Could you run Blender from the command line and show the output?

Hi,

I solved the issue.
I didn't specified the path for the SDK.
Instead, I installed standalone addon.

Thanks !

Regards,
