some static mesh collision not generating overlap events

i have a fireball that spawns an enemy when it overlaps an object. for some reason it works when overlapping some static meshes but not others. they both have the same collision presets and they both use simple collision. why is it not overlapping on some?



For overlap events to work, both objects need to have Generate Overlap Events enabled, collision est to at least Query Only, and each object’s response to the other’s object type should be at least set to overlap
So if your wall is WorldStatic and your Fireball is WorldDynamic, then the wall needs to overlap WorldDynamic, and the fireball needs to overlap WorldStatic, and both need to generate overlap events

Well i figured it out, kinda. the instace in my level had overlap events off. but the collision that was working doesnt even have the option to turn it on or off. does anyone know why?
