Yep, I used the “Projection Zones – Beam Attenuation Map” feature of Pangolin to do that
It’s a real novel feature and very simple to use
Basically set the camera up in place with the lens cap on then go into projection zone and turn on display grid and then draw on the map where the camera is.
You can apply varying levels of attenuation, in this case I used 20%, I could have gone higher so that the beam doesn’t quite disappear but I am unsure as to what level would start to damage the camera so I kept it low.
The other great feature is that you can apply different attenuation maps for different show effects, i.e. Targeted beams, graphics, atmospheric, etc.
