This is a major regression from UE4. This is a development halting bug on UE5 (5.0.3) with Chaos:
If actor A hits actor B, but actor B is attached (welded) to a parent actor C, then the produced hit event will point to A and C instead of A and B.
This is a regression from UE4, where it worked as expected.
This is extremely problematic, because I have no way of knowing which child was hit, and I can’t relay that information to other systems that may want to affect (e.g damage) child actors.
I’ve submitted a bug report but I have no idea where it is or how it’ll end up, so posting this here as well, I’d be really happy if an Epic staff member can shed some light on the situation.
