StaticMesh doesn't register hits if not a root component

[ClockworkOcean]

I’m pretty sure this is how it works.

I can’t find the article right now, but I saw somebody saying as much recently…

Here’s a couple of ( old ) self referring articles about it

Collision Component MUST be placed in root

See this topic: Bouncing projectiles have no collision - World Creation - Unreal Engine Forums This is such weird behavior + so bothersome when using inheritance that I assume that this is a bug. I mean we have like dozens of collision-settings but not adding a random collision-component (doesn’t even have to be the one you will be using) as the root will break ALL collision-checking for this object except for pawns. Reproducible.

And another

Sweep only works with Root component?

Days of work to isolate that issue. Title says it all, Sweep on Set Actor Location or Add Offset will work on ROOT component ONLY!! That’s quite terrible, my BP is composed of multiple StaticMeshes, and only root will collide with player (very fast moving object). Am I doing my setup wrong? Is there an option i’m unware of? Or is it by design (if so, a note on sweep tooltip would have been much appreciated) Thanks

But I have this more recently also…
