Released: August 1st, 2019
OpticStudio 19.4 Service Pack 2 contains the following fixes and enhancements.
Programming
- Load Archive - The LOADARCHIVE ZPL keyword now correctly loads a ZMX file which has been saved as a different name from the ZAR file. This is the same functionality as loading a ZAR file via the user interface.
Usability
- Optimization Wizard - The Optimization Wizard, found in the Wizards and Operands dropdown button in the Merit Function Editor toolbar, now uses Express Mode correctly.
- Zemax License Manager - The new Zemax License Manager (ZLM) was updated to show the accurate seat count when increasing the total number of seats on a license.

Non-sequential objects
- Boolean Native object - Boolean Native objects now handle the ray traversal order correctly when using Array parent objects.
