Is it possible to attach an actor to a Blueprint?

When I try to attach a moveable object to a blueprint it says “cannot attach actor to an actor with a blueprint-declared root component!”

Is there a work around or are you planning on changing this?

It is now possible to do this and this should be in the next rocket release.

OK that’s good , do you have any idea when that will be?

If there are not any severe hitches, we are planning for a late October or early November release of Beta 5. This is of course not a guarantee as we cannot predict all future problems that may occur.

Thank you,


Hi ,

I have updated to the newest version of Rocket and am now able to attach an actor to a Blueprint. The problem is when the Blueprint animates it will not move with it.

Video of the problem can be found here.

The red block is a blueprint and the white block is the static mesh. Both actors have attachments , but the attachment for the blueprint does not move when the blueprint does.

Is there a way of getting other objects to move with the blueprint?
I could do it with Level Blueprint , but I would prefer not to because it would involve manually creating the same actors multiple times.


Hi Toxic,

Just wanted to give you a heads up, Bruce is aware of your reply, but will not be back in the office until Monday.

Thank you for your patience,


Is the part that is moving the Root of the Blueprint? An attached actor will follow the Root component of a Blueprint, but not just a standard component of it. This is because the actor follows the Blueprint’s transform location information, which is determined by the root component.

It works Thanks.
