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?
