While preparing a simple DF example (with all the default HB Radiance parameters), I realised that repeating the simulation changes the DF values as high as 80% for specific points. I would have two questions on this:
Am I right in assuming that this is due to a random component in the Radiance sampling procedures? If yes, do you have any reference in mind to suggest?
Based on your experience, how can one make the Rad parameters more strict, so that such variations become negligible?
As always, many thanks for the great support.
