Constraint Fails When Attaching Actor To Actor Component

Development World Creation

Repro Steps:

  1. In Blueprint 1, create two static meshes and a physics constraint between them.

  2. In Blueprint 2, with a child actor component of Blueprint 1 and a static mesh.

  3. In Blueprint 2 using OnEventPlay, use the Attach Actor To Component to attach Blueprint 2’s static mesh to Blueprint 1.

  4. Note that the physics constraint in Blueprint 1 is no longer functional.

Hi Korenski405,

Could you post a screenshot of your setup? The AttachActorToComponent node didn’t work with the ChildActor and StaticMesh for me. I used an AttachTo node and everything worked fine.

Ill give the AttachTo node a shot tonight. Appreciate the feedback!

Did the AttachTo node work for you?

This is worse when you try to do this in C++

I also had that problem. I was attaching actor to a pawn - a tank track to my tank body, but when i hit play, my wheels, constrainted to my track root, deattached from my track. Sow’ what’s the reason?
