Hello,
I saw some help pages online that mentioned the Ray Trace Control (it is even in the Zemax Help System), but when I search for it in OpticStudio (20.3), the Ray Trace and Lightning Trace is greyed out and unable to be clicked. Did these features get removed recently or someting? I am using Zemax 20.3 Premium edition.
Thanks,
Jake

Hi Jake,
Ray Trace and Lightning Trace are only able to be used in Non-Sequential Mode. If you are currently working in Sequential Mode, then they will be greyed out in the search. You can check which mode you are in under the Setup tab:
There is some guidance on the difference between modes here and here.
Best,
Allie
