How to exclude something from an event ?

I created an explosion, but I would like the explosion to not affect an element (character or object)

How can I do that ?

For collision itself should help this

But if you are talking about explosion you probably mean also some kind of physics field.
Then happen if you are using old Radial Force Field or new Physics Fields Components. So what exactly are you using?

But

Do a sphere trace at the explosion center with the explosion radius to gather overlapped actors with a filter and just apply the damage / physics push to the filtered array.
