Rayfin Script Builder Missing Scripts after v3 to v4 Upgrade
Issue: Following an upgrade of Rayfin Camera from v3 to v4, I cannot see any Scripts in SubC Rayfin Script Builder.

Solution: Reboot the Rayfin camera after updating to v4 for the first time and the scripts will be available when you reconnect to the Rayfin through the DVR+O / SCI / RCS UI and open Rayfin Script Builder again.

Menu → Other Rayfin Settings →
Controls → Restart Camera
Scripting → Open Script Builder
