YafaRay question: Possible removal of Bidirectional Integrator?

Support Other Software
1

Hello,
In my opinion, the current implementation of the YafaRay Bidirectional integrator is buggy, flawed and its design is very different to the other integrators.

My question is: do you believe it’s worth maintaining? Or we should remove it from YafaRay and move on?

Do you think this is still useful? Is somebody using it for actual production renders?

I never use it. So, if you find it buggy, my vote is positive.

Hello,
Based on several comments and votes and my own tests where I can see the Bidirectional integrator often gives different results (apparently inconsistent and probably wrong) respect to the other integrators, this is what I’ve decided for the Bidirectional integrator in YafaRay-E:

  • To be respectful with the few users that might be using Bidirectional despite its problems, I will not remove the Bidirectional integrator from YafaRay-E yet.
  • I will declare Bidirectional a “deprecated” integrator, with warning messages in the UI and the Log, recommending not to use it and explaining that the Bidirectional integrator:
  • Will probably give incorrect render results.
  • Will not be supported anymore. No fixes or improvements will be developed for it in the short/medium term.
  • May be removed from YafaRay-E in a future version.

Thank you for your comments and best regards.
