I do not comprehend the philosophy behind LightCache settings.
Retrace threshold was already bordersome annoying. Sure, it would solve leaks and add 20-30perc. render time overhead if no glossy refractions were on scene, but if there were, suddenly the render time would multiply and sky-rocket.
Giving you a choice when to use it, because for that exact reason, it can't be left on default.
Now there is another parameter to basically do just that as well, but perhaps to do only that without affecting refractions and glossies. And again have check-box.
Fucking secondary GI algorithm with unnecessary settings.
Surely all of the above could have been integrated to work automatically. I mean if the algorithm is shit first place, then have it do necessary tweaks always, what is the point of letting the users try removing precision until it collapses to artifacts to give
him slight speed advantage ? I hope they at least did the defaults on it as bomb-proof as claimed.
All the other things are nice. Little features, nothing I care about.
Hope Corona takes full integration of 2016's physical camera.
