Hey -
From what I can see of the code it looks correct. Can you test this in the blueprint using the mesh by adding a “Get Socket Transform” node with the target set to your skeletal mesh, the socket name as your thruster, and the transform space set to RTS Actor. Break the Transform return value and wire the Location into a Print String node. If you call the Print String on a keypress it should show the relative location of the thruster on the screen. This can be tested further with a “Get Socket Location” node, however this will assume Transform Space is set to World.
Cheers
