on Arma 3 latest APEX RC.
There's geometry in the Viewpilot LOD of the ENVG, making it nigh on impossible to see anything when in 1st person with the NVG's in the down position.
it's an easy fix as i'm sure you are aware.
I'm not sure if this extends to any other ENVG model.
sorry if i made a booboo with the report.
