If you are rendering the same object to different display types (for example, to both a large screen and an immersive environment such as a head-mounted display), to obtain smooth visualization on both display types, you are likely to need to apply different amounts of filtration for each.

To enable you to do this, Tracker provides a second set of VRPN trackers, which are output with the existing ones. For easy identification, the names of this second set of VRPN trackers are suffixed with _2.

**To enable second filtered VRPN trackers:**

1. On the **System** tab, select **Local Vicon System** and in the **Properties** pane ensure **Show Advanced** has been selected**.**
2. In the **VRPN Stream** section, select **Add Filtered Tracker**.  
The second set of VRPN trackers includes customizable One Euro filtering. For information on adjusting filtering parameters, see [Creating an object](https://vicon-help.atlassian.net/wiki/spaces/Tracker39/pages/14060303).
