VarToggle function in CAMERA.CFG


I wanted to hide the co-pilot in the front cockpit view on a biplane.

In the SDK documentation, NodesToHide is deprecated.
Instead, I think I read that there is a new VarToggle entry that lists local variables L: and switches these variables from 0 to 1 (or 1 to 0) when needed to hide an element of the aircraft into a precise view.
In the DEV Mod, there is also a way to enter a list of nodes that must be hidden in a given view.

I tried both methods and neither worked.
The process via the DEV MOD created an additional entry in the CAMERA.CFG:
node.1 = ModelDefinition:Interior#Name:PILOT_1

I recompiled the project but the function in the simu does nothing.
