When playing, the lens can pass through any objects, including Landscape, brush
The camera?
can pass through any objects
Turning collision off would still allow the camera (?) probe to intersect freely with geometry. So… what is really needed here.
turn off the collision of all objects in the scene?
This is going to be expensive.
This is true, how do you switch the player controller to it by the way?
You could disable collision on the Default Pawn and keep the C++ flying bit:
Definitely more efficient than Get All and then (potentially) restoring previous states…
The thing is that we (I) do not know whether OP wants collision or clipping - getting mixed messages from the topic vs description.

Is this desired result or an issue? I assumed that’s what they need.
