Sphere trace in control rig only works with actor with the collision object type of "World Static".

One of our customers reported on UDN that sphere trace in control rig only works with actor with the collision object type of "World Static".

Is that by design or a bug?

1. Create a control rig blueprint asset and add a sphere trace node.
2. Set start and end vector of sphere trace node just like the screenshot below. [Image Removed]
3. You can find out that only when the object type of the actor in the scene is set to "World Static", the sphere trace will work correctly. [Image Removed][Image Removed]
4. It is not convenience in many cases, such as tracing a dynamic door or a moving platform whose object type must be set to world dynamic for gameplay tracing.
