I started a new Blueprint driven SideScroller without adding the starting content. I put in my own meshes and placed them in to the world. Now i added a blueprint with a trigger box. But the default character is not firering any events. No Overlaps Actor or OverlapsComponent Events nothing. In the EgoShooter presets it allways worked but here nothing happend.
Ok solved it by my self. For everyone with the same problem in the future.
In the Character Blueprint the CapsuleComponent has a property Generate Overlaps Events. That has to be checked. Its not checked by default.
