(Resending with smaller screenshot to avoid moderator…apologies if duplicated) Success! Thank you Andrew and Trent. My development version now has visible tractor (green) and pressor (blue) beams with a cool SwiftUI animation…at least for _my_ pressors and tractors. The fact that only my tractors are visible means I don’t need to implement the other case. Attaching screenshot of current version including active tractor beam.
