While we can turn off the selection beam, we can't seem to turn off the swirling scripted lights of a scripted object.
For machinima, this enormously complicates making certain scenes look "real."
And the draconian step of turning off all particles means many special effects can't be filmed at the same time.
Fixing it could also be a workaround for the persisten swirling lights when UI off issue, since it would allow us to turn the lights off even with the UI on. Jira Linked.
I have tried Tools>Show Select Beam = off, and tried Advanced>Debug>Effect Color Alpha=0
