Hi! Both sliders are activated only when you work on a multi-row 360 product view. Here's an example of such a multi-row 3d product view (note how you can drag it horizontally and vertically at the same time):https://www.webrotate360.com/examples/b ... model.aspx
They are there to fine-tune the amount of mouse & touch drag that is required to trigger either a vertical or horizontal spin as per the example so you can pick optimal numbers that work best for the number of 360 images in your rows and the number of rows themselves. I hope this helps!
