Very likely, at the moment I have done tests only with a LuxBall5 scene made only of matte materials (and now the rendering should be correct in that case). I'm also aware that it is unable to correctly render Psor's cube.
I have lately fixed the path weights (in order to produce correct renderings), a couple of other bugs and written the code to connect the light path directly with the camera (i.e. a basic requirement to render caustics).
Side note: BiDir can be seen as blend of different rendering methods: path tracing, light tracing, etc. By using constant path weights I'm effectively taking the worst (i.e. noise) out of all rendering methods
MiS solves this problem (by picking the best instead) but it is the very last step I'm planning (i.e. don't worry too much about the noise in current hybrid BiDir renderings). Before MiS, I want to get everything else right.
