Helicopter downwash effect on vegetation should be collective dependent

Version: All

Frequency: Consistently

Severity: Low
(Low - quality of life, workflow optimization, rare enough to not impact production, etc…
High - critical but workarounds are available, important feature not working as expected, frequent enough to impact production
Blocker - prevents from working on the project, prevents from releasing the product)

Marketplace package name: if applicable

Context: What package? When editing or mounted from Community? In main menu or in flight? etc…

Bug description: Currently the vegetation movement caused by the rotor downwash seems to be controlled by two factors, rotor RPM and the distance of the helicopter to the vegetation. To make the effect realistic there should be an additional collective dependancy. A helicopter that is sitting on ground with full RPM will have little to no effect on the underlying vegetation until the pilot starts to pull on the collective and downwash is created. The video below shows that very well.
In the sim the effect will be fully active even when the collective is fully down.

There should be a way to implement the collective factor in such a way that it applies well to all helicopters. For that I would recommend to scale the effect up from 0 to 50% collective input, above 50% to 100% it can then remain fully active, if the other two conditions (distance and rotor rpm) are given as well. If this is not an option maybe us devs can have some kind of trigger to activate the effect with custom code?
