4. Enter values for the current trace in the appropriate boxes.

If you already know the IOR value, select Fixed IOR, then enter the

function of the distance between span start and span end, select
Fixed length instead, then enter the distance value.

5. Press Apply to confirm the changes.

the changes to both unidirectional traces. Select the option that better
suits your needs.

7. Press OK to return to the Trace Info. tab.

Note: Modifying the current trace parameters affects the trace that is displayed.
