Sanity check to ensure the handle is safe to use.
Parameters
| Name | Description |
|---|---|
| bDeepCheck | to check that the transformable object it wraps is valid AND can be transformed. Default is true. Some handles, such as control handles, will only be bound to a skeletal mesh once the level sequence has been opened, but their control rig pointer and control name are valid, so they must be fully loaded so that the constraint can be updated later. bDeepCheck = false will be used for that purpose. |
