- How to install
Open Blender, go to File > User Preferences > Add-ons (or Edit > Preferences > Add-ons in 2.80 or later), then press the “Install Add-on from File” button. Select the ZIP file that you downloaded after purchase and install it.
After installed, tick the add-on checkbox to enable it, and save your user preferences so it stays enabled.

After you install and active the add-on, you can see a AV Kit panel tab in the 3D View. (Press N to bring up all panels)
