I run a tolerancing with my optical system which includes a tolerance script to get RSRE operand in MF.

At first, the warning massage "when using vignetting factors, user-defined fields are required" was popped, then I continue to run the tolerancing with Sensitivity Mode and 5 Monte Carlo Run/Saves.

The Analysis of Tolerances shows that there is no any RSRE and Criterion change in both Min/Max and Monte Carlo runs

I checked the MC_T0005.ZMX, the RSRE and MF have been changed as I expected.

 I’m not sure if the setting vignetting factor is the root cause here. What should I do to make MF operands update correctly in the Analysis of Tolerances?

Thanks
