Thk to all in advance and sorry my poor english...

It's the indirect light, I'd say...
Indirect light needs very long to get noisefree...
you use 0.6? ('cause of bidir and burn)

These pics look awesome! If you want to get them noisefree faster, you have to use more direct light, but I'd say, you just have to render it longer! Indigo needs a lot of time!
Also, I'fd say, 0.7.5 is faster than 0.6.6...

Which App do you use?

Welcome to Indigo comunity, btw

Wow how many questions for me ...

now i dont have problems for long time render...

My indigo is last estable .6
only have a skylight from blender... (sunlamp) in this scene.

In indigo only i can have one sun...

I will have render with background and various meshlight this scene or only with variuos meshlight?

Thk another time...

Depend of this parameters this noise ?

<max_num_consec_rejections>100</max_num_consec_rejections>

<strata_width>14</strata_width>

I believe that i read that strata width dont have efect in render ... in version .6

Thk.

miseca what equipment u have? cpu and ram most....

only with meshlight, I'd say... I mostly don't like bg-light... (Sometimes, it looks nice, through)

<max_num_consec_rejections> will slow down the render, the higher the value is, as far as I know, but it will give better quality

<strata_width> depends on if you use mtl. or pathtracing mode... as far as I can see it in your scenes, you're using mtl, so it shouldn't effect the scene (or? Never really thought about that... But there's a description in the inifile.txt...)

You are right Kram, <strata_width> is used with path tracing (mlt off). Actually it's not implemented anymore in 0.7tx issues.

Transparent/glossy surfaces and subsurface scattering take more time to converge, because light is scattered in an unpredictable fashion; this creates a higher level of noise, thus needing more time to converge.

Me parece que no has echo nada mal

Thk o deberia decir gracias

My pc is a pentium dual 2.8 ghz y 1 gb Ram.
Nvidia 7500 se

i will probe with more meshlight and background off

well, there is a post that the people put your scenes with render and the
xml file too?

I think that learn more with this...

Thk people...!

Using a sunlight, I find, makes it take a lot longer to get a clean image, particularly when you have reflective or refractive objects.

Miseca · Post by **Miseca** » Mon Mar 19, 2007 6:21 am

Thk for reply, i find that in the same time 7-8 hrs. this pic with 3 emitlight
look fine.

And this one, same scene but only a sunlight.

http://personal.telefonica.terra.es/web ... nlight.png

Yeahh, now i can render various test too, but with scene in interior ...

now, i believe that this render are fine....

I will post new render next time...

Bye
