I have a trigger generating overlap events attached via socket and being moved with skeletal mesh animation (kinematic trigger). Sometimes the trigger can hit another person and sometimes not.

Drawing a series of debug boxes every tick show the trigger volume is not always overlapping the target, so animation is moving the trigger too fast.

I have tried turning on CCD but to no effect, does this option work for triggers?

Or is the only option to perform more accurate sweep tests, between trigger position updates?

Hello, did You get any more insights into this? I think that ‘use CCD’ is relevant only for physics simulating actors. For kinematic actors, ‘sweep’ is equivallent. But I am not shure if I understand it correctly, can someone confirm or deny it?
