Help me some one !
I set up this scene but I dont know how to remove the noises !
This is my scene settings : No supersampling / Samples : 376.34
size: 800x600
After about 2h it was still like this ...
Help me pplz ... id appreciate that !

Interesting test scene.
Can you please put the .pigs (packed indigo scene) online somewhere?

Unfortuatly not cuz I made a bad mistake and closed my max ! No backup scene even
But I wrote down its profile !

Re: Help me some one !
such Firefly Dots can be "removed" by using Supersampling, if you have enough RAM, then go for it!
SuperSampling doesn't cost any Rendertime but RAM only...
For this kind of Scene MLT + BiDir as renderbode could be better then pure PT + BiDir

Re: Help me some one !
Thnx zom-b I dont know my ram is adequate or not ; its 4G
my super sampling was 0 .
And sorry I didnt get the last part ! what is MLT , BiDir ? and what does pure PT means ????
Im really new to indigo i need some help !!!

Open Indigo with one of the included test scenes. Look at the panel to the left side of the graphics window labeled "render settings' and change it from the default panel "Imaging" to "render settings"
There is a little menue called "render modes" that has four entries to choose from:
1.Pathtracing which is single directional path tracing and is good for exterior ore directly lit scenes with lots of mostly diffuse surfaces. thsi is also the only render mode with GPU support.
2. Bidirectional Patracing or also often abbreviated as PT + BIDIR
3. Pathtracing with MLT (Metropolis light transport)
4. Bidirectional Pathtracing with MLT (BIDIR + MLT)
The latter two are what will be most useful for your scene as it has lots of irregular (non coplanar) shaped objects with a specular (glass) material.
Ultimately all the render methods should result in the same image. However, even using the most sophisticated GPU supported Pathtracing you will have to wait for ages for the caustics to show up. Using one of the latter two mentioned modes caustics will show up relatively quickly.
As Zom-B already mentioned to remove the fireflies you will have to increease supersampling. The fireflies are also the result of the many light path that have to be evaluated (traced) through the specular/glass materials. This will become even more ptronounced if you use a higher number of smaller light sources as this will make tracing the light paths more dificult.
I hope I will be forgiven by the render gods if my explanations here are a bit to over simplifying
