Hi guys, that’s my very first post on this forum. Could you please help me with pretty easy problem for you-programmers than for me - a sound designer with 1 hour of UE experience 
I need to do an effect that everytime I turn around (there’s always a darkness behind me) some SFX are played (whispers f.e.). It doesn’t have much to do with Attenuation, cause I need those sounds to be played everytime i turn back, and which crossfade 100% with other sounds that I used to have in front of me. Thanks in advance.
