Daros, are you using the same method of chopping up the image into render regions and sending each region to a computer for rendering? Do you have to overlap the regions to hide boundaries or is that not necessary?

[tlass]

Mihai if you split for example your image in four pieces,
my experience is that no overlapping is needed...

everything matches perfectly....

[daros]

Yes, we have to render one pixel more for each side of the split.
The border pixel is darker.

A total of 100 hours of calculation time for this image.
I try to obtain a Halogen-like photometric effect.
Each lamp has a 72 polygons reflector and a 6 polygons emitter.
The total is of 26 lights.
The result is still noisy.
Light bounces 8.
It is possible to archive the same result in shorter time?

i work the same subject

but what your computer

100hours is big !!!!!

what your number for polygone emiter ?

[daros]

Hi,
26 lights with a simple cube for each emitter.

hi can you post an image slice of the lamp, i think the effect you get is great... i dont speack ingles well...

[Mihai]

Is the material on the inside of the lights a metal, or plastic? Try putting a diffuse on the inside, make it almost white, and leave the metal material on the outside so it looks good.

[Maya69]

have try disable indirect reflection and refraction ?

[daros]

I think we using the wrong approach.
We are splitting the renderings on multiple CPU using the render Region.
But for our test the Render Region is not optimal for Maxwell.
So, the rendering time i posted yesterday is not the result of 100 hours calculation of a single computer but one hour of 50 dual xeons.
The problem is that the result is much better on a single processor after 9 hours. For that i say that may the render region is not optimal for Maxwell at moment.

Sorry Mr Maxwell, we made something wrong and you are not so slow as i say yestrday.

you can se the results

9 hour on a single cpu


1 hour on 50 cpu using Merged render region and not MXI files.


Sorry again for the wrong information of yesterday.

ouf i prefere

just a litle question

what your parametre for light fog

[daros]

I set the standard settings

Volume scattering, absorption 0.2, Scattering 0.2.
That's all.

David Rossmann

[Maya69]

ok

i try with 0.2 both a fog parametre

but the fog is big

Hi all,

The split method to render one frame among different machines won't work for maxwell.
At the moment the only way is to render in cooperative mode under our net manager. In version 1.1.33 ( coming very soon ) the cooperative render have been improved considerably.

Best regards.
