Indigo Renderer Forum

I using the Bidirectional PT method, with glass acceleration, SSF 3, MNCR 1000, but i still do have a lot of fireflies! Please help me!THX ! Im using 2.6.1

I did not set any sub divison, UV mapping, SSS, Exit portal etc

Is that any wrong about this rendering?

At a quick glance you could try SSF 4,5,6 or let it render longer, the fireflies might clean up into caustics.

But my indigo only can set SSF maximun to 3 only, and my SPP is 22xx already!

Hi William!
..actually, I don't see any fireflies!
Maybe your corrected image can't show them clearly. Can you post the original image?

BTW, your maximum supersample is set to 3 inside SkIndigo, isn't it? You can always open your *.igs exported file and look for the parameter <super_sample_factor> and change the value manually.

I'd probably try Bidir MLT with this type of scene. Should be less fireflies and quicker convergence for caustics. Make sure you have GPU disabled or else Indigo will force simple path tracing.

To ENSLAVER : thx for your suggestion, i set the SSF to 6, i finally get it a better result!

To Pibuz : Ya is true that i've corrected that image, and thx for the zip7 solution, now i can set them manually!

To Whaat : Ok, i will try it my next scene with Bidirct MLT, Thx!

As other said, MLT will help, and by the way, MNCR has no effect with PT, only with MLT.
