Description

When attempting to apply torque to a ragdolled skeletal mesh, nothing happens, regardless of the value used. Applying an impulse works as expected, but adding torque seems to have no effect.

Found in 4.10.2 binary. Reproduced in 4.11 Preview 2 and Main CL 2829742

Steps to Reproduce

1. Open the editor (Third Person BP Project)
2. Create a Pawn and give it a skeletal mesh component
3. Set the SK_Mannequin as the skeletal mesh
4. Set simulate physics to true
5. In the ThirdPersonCharacter BP, create a variable of type Pawn and make it public and expose on spawn
6. Drag an instance of your Pawn bp into the level
7. Set the Pawn variable in your ThirdPersonCharacter to your Pawn in the level
8. In the ThirdPersonCharacter BP, on F pressed, Add Torque on the Pawn's Skeletal Mesh Component.

Result: When F is pressed, nothing seems to be happening to the Pawn's Skeletal Mesh. However, replacing the Add Torque node with an Add Radial Impulse node seems to be working as expected.

Expected: Torque would be added to the Skeletal Mesh.
