Strange! I also use A5 version!

Same here. If I open your scene and click render, the render is very different than your. No caustic.
It looks like some radius is too big.

Polymax, if you render one image with path tracing and one with bidirectional path tracing modes, these could serve as a good reference for people to understand the differences between the algorithms. Path tracing should get both the underwater and the wall caustics noisy and bidirectional should only have problems with the underwater ones.

Chamfer for glass - gives fireflies, nothing can remove them. Even a total shutdown visibility of the sun! It's a bug!
Only tomorrow I can get a good result ((.

2 iliyang:
PT + PT can not cope with this task in a reasonable time!
Bidir - give similar results with the VCM, but will not be seen underwater caustics.

The purpose of this test - solve the complex task in the exterior to understand the capabilities of the algorithm. At the moment, none of the popular renderer is not able to!

Have you tried to use (or change) AA filter? Some time it helps to remove these dots...
My Ducati or a render with Corona.....mmm, hard question!

I'll  try, thanx!

I tried but it did not work (!

The point I was trying to make is to compare the quality achieved by PT, BPT and VCM in the same time (say 3 hours). I understand very well that neither PT nor BPT will be able to produce an acceptable image, but that's the point of the test. I'll be giving a talk about VCM at Siggraph in a month, and if we can get this comparison on an awesome scene that highlights the strengths of VCM, I can show the images in my talk, which will give Corona some publicity.

Okay, I'll do it :)

Take your time - better looking images means more fame for :)

If you do the comparison for iliyan, use path tracing mode of VCM renderer, not progressive with PT/PT, as you'll probably get different results.


Also upload the problematic scene with fireflies as a bug

Intermediate tests.
The purpose of the test - to achieve optimum noise in the minimum time, ie it is more practical test.

Nice test!! So, for now, the best solution (quality/speed) is obviously RT+HD

yes, in this scene. But for example in a pool scene VCM is the winner

Guys, does anyone have a nice comparison between bidirectional path tracing and VCM? I'd love to put some Corona image on my Siggraph slides.
