How can I get child bone's new location after set bone rotation

I use “set bone rotation by name” node for shoulder bone. I need hand bone’s new location after rotate and I use “get bone location” node but its give me location before rotate. How can I get updated location.

Where do you call GetBoneLocation? It’s possible that, because it takes some time for the processor to move the bone, even tho it’s a microsecond, when you call get bone location, this is executed before the actual transform was applied, try using a delay before getting the final location of the bone to see if that’s the problem.
Hope that helps!
