Invoke PEXOCCSetPickID to create an attribute output command which sets the current pick identifier attribute in the renderer's pipeline state according to the value specified by pick_id.
The pick identifier is returned as part of the path when you pick a primitive. When you are structure editing, you can use the pick identifier for navigation purposes.
