Fumefx and Mental Ray - harlequin - 05-01-2009
Greetings all.
Here i recreated my problem on a simple scene so that everyone see what is going on.
http://dl.free.fr/oTNSQnQWu
I have a problem with Mental ray it seem, because when i try it in scanline, i don't get that result.
As you can see, my actual smoke is flickering , mostly as we get near the end of the sequence. We can also see some square artifact in the shadow casted on the ground. I tried getting smaller tile size, but my square artifacts only get smaller.
Anyone can help ?

Hello Pierre,
Can you please post your scene so we can check it here?
Thank you.

Thanks.
As soon as i get home tonight, i will send it on a free space and post the link here.
The lighting department suggested the following:
* set filter size and density to 1 if lower ( done )
* increase number of rays ( done )
* increase sample reflection on mia_material ( i have no relfection in scene, it shouldn't affect anything? )
* optimized reflection turned on in your mia_material may cause flickering ( again, i have no relfection in scene, it shouldn't affect anything? )
* Check if Area Light or Reflective Panels are not causing the flickering ( i lighted my scene with two spotlights.)
* If your objects are not moving, use "Append Mode" instead of overwrite each FG files per frame. You can preview the FG points using the diagnostic panel in the "mental ray" options.
Let's wait and see in my scene.

I'm back. Sorry for the delay.
There is bad geometry on the aladin lamp, the model was free on the net. I know why now.
Here is the file. Thanks for your time.

Hello,
Would it be possible that you attach one .fxd file for a frame where renderinf artifact is visible ?
Thank you.
