Set Actor Location doesn't move children meshes when the actor root is the 'DefaultSceneRoot'

Development Programming & Scripting

When I do set actor location and the root is a scene component the children don’t move with it. They stay still in place.
If I make the mesh child the root though everything works as expected.

Note that I have carefully set the children’s location as relative (the default).
I have no idea why that is happening and I’d like to know as I’ve spent hours troubleshooting this and I had no idea this would work. I’m now thinking that I never want to have the sceneroot component again ever!

Can you explain a little more what the issue is?

Yes, sorry I must have wrote this question hastily. So the problem is that the children of the sceneroot component don’t move relative to it when I use setActorLocation.

So if you have an hierarchy like this:

— DefaultSceneRoot

— — staticmesh1

— — staticmesh2

If you use setActorLocation, neither staticmesh1 nor staticmesh2 move? Is that it?

SetActorLocation moves the actor itself - root and children. To move only the children and not the root, you should select the childrens to move and use SetWorldLocation, AddLocalOffset, …

Precisely. That is my point, the default scene root moves but the children do not move when they should be moving. If I make one of those other components the root though, eg the mesh then both the root (the mesh) and its children move together.

Yeah, that’s weird. Does it happen with every new BP?
