When im on foot or in a vehicle driving, i can see the buildings and terrain. basically everything. When i get into pilot, co-pilot, or back of a heli, the heli itself disappears, along with everything, including buildings and telephone wires. when the heli gets into the air, the only thing i see is the heli, excluding the rotor blades.[Sometimes i see the heli in the air, other times i dont]
In edit mode, this issue wasnt reoccurring.
