PoseableMesh child bone doesnt use parent bone transform

Hi,
I’m using poseable mesh to do simple animations on vehicles.
Let’s take the example of a tank to explain the issue:

2 bones:

  • Turret → parent
  • Gun → child

When i set bone rotation on Turret, gun follows but when i set bone on rotation on Gun, it doesnt use Turret transform but uses the transform of the SK.

The issue is avoided when i first set rotation to Gun and then apply roation to Turret

I use the node “Set Bone Rotation By Name” and the referential is either “World Space” or “Component Space” there is no option to use parent bone space.

Do you have any suggestions as to how to fix this? Should i implement my own set bone rotation to utilise parent bone transform?

Thanks
