Indigo Renderer Forum

images of the same scene!!, one to 15 hours of render, the second to 29 hours of render.... they are equal.... what it is the time limit where it is useless to continue the render.??

le immagini sono della stessa scena!!la prima dopo 15 ore di rendering, la seconda dopo 29 ore...sono identiche...quand'è che non vale più la pena far continuare il rendering?

first...15 h.

second...29 h.

If you post such pictures for comparison, please use the original png files,
the jpg compression of your pictures is horrible

how long a scene needs to render is a question that is totally depending on the,
yeah..... you are right.... at the scene!!!

there are a lot of aspects of a scene, that could stretch the time to a "noiseless Rendering".

for example Bump Mapped Materials need more time than diffuse materials.
transparent Materials that causes caustics need more time than non transparent materials.
And so on and so on...

Indigo is powerful in rendering complex scenes (nearly) as fast as simple ones, it gets slowed down by complex materials and light (-reflections) in most cases...

Best answer for your question is, to check your rendering after some hours, if it looks good for you, it done

I like it that Indigo will go forever
YOU get to decide when it is done!
The only problem is that we can't stop and restart it. So if you made the decision too early, you gotta start over.

The time to reduce noise apparent in the image rises exponentially as you render.

For example, for a render to look better than the 17h, you need to render for 4x 17h = 62h

There is no "magic" number that you should stop rendering at.


I have rendered a test image for about 180 hours (x a few computers, my render farm), and it STILL have noise!



Here is a tip though: render at higher resolutions than 800x600. I like 4000x3000

When you resize the image down for viewing, apparent noise is reduced.

I have already made a will the method of the reduction, if you want to read my article it looks for "fili-reduction" in this forum...but I test it a lot of times, in some cases the image resulted darker...you see my article...
thanks to everybody, but I have not resolved the problem...
the solution is in the power to stop and restart the render.. said as from silverman....excuseme for my language

not sure, but one image seems to be bigger in file size than the other, might be better image quality in one than the other. again, not sure.

Yes that is sure, image with more noise are bigger !

Yes, see your article:
