Hello there !
I have a problem with one of my Blueprints
I’m trying to detect all actors with an interface with a SphereTraceByChannel but my npc isn’t detected. Can you help me ?

Blueprint inside my BP_Hero (ThirdPersonCharacter)

BP_Hero Class Settings

BP_pnj_dialogues_alt_test (NPC) class settings

When I try to interact with this blue stupid thing >:c

By the way, if I put a print just before my second branch I do detect actors and objects like so :

Can you help me ? It would be awesome !

It was the wall behind my npc causing the sphere to turn green. The NPC isn’t even detected by my SphereTraceByChannel ;-;

Under collisions I set the preset to custom and I changed the Trace Response Visibility from Ignore to Block :

I hope this can help someone
