Pawn sensing don't detect my hero

I put a point break on my even on see pawn (sensing) but nothing when my character is on front

Did you setup your AI Perception component to detect all affiliations? Click your AI perception component, in the details panel under AI Perception → Senses Config → Sense → Detection by Affiliation → Check all boxes.

Currently there is no way inside of blueprints to set who is on what team for AI perception, you have to do it in c++ or create your own blueprint system to handle that.
