Auto update does not work if properties in Lens are changed
When I change the Refraction index property. The first change automatically updates the refraction path of the ray. Sometimes, further changes in the index update the ray, sometimes not. (I have yet to tie down a repeatable sequence to replicate, sorry.)
I've experienced the same or at least similar thing. 'Mark to recompute' the ray, then the recompute works two times but not after that.
As i see it, there is no auto update at the moment.
Changes in the Lens properties do not have any influence on the present rays automatically any more. You have to trigger (Re)start Simulation manually to get the rays updated. I do not see a way to change this behavior. Therefore I close this issue.
