I’ve had an issue with a night vision material on widget Camera “Plane” and in New 5.1.0 was not working at all and this setting “output Alpha” nailed it!. Thanks. (just to clarify with this setting un-ticked in 5.0.3 and previous versions it worked fine):
Before NightVision is Set to ON
After NightVision is Set to ON with no Output Alpha ON
After NightVision is Set to ON with Output Alpha ON
