Flickering in Animation

[martinzip]

Hey eyeonestudio

yes there are two surface really close to each other, the liquid in the bottle and the bottle surface are next to each other ...
Indeed I had coherent modus working ... so next try ... for the glas material ...

thanks for your help

i think, you need at least 1000 maxsamples. Tweak it in live viewer, until noises disappear.

I am working with 1500 samples
In the reflection there is a lot of noise, which I cannot eliminate with ae.
Next step?

Next step check my test scene. It's very well with some tweaks on kernel and material. Notify i have to use "coherent ratio" + "static noise" to decrease the noises. It's ok with 256-512 samples on DL or PT. Btw, not a good idea to try the removing the noises in ae.

Ray epsilon changes a lot, the noise disappears in the reflections of the hydra image, the bottle looks completely different but no noise at all ray epsilon 0,011 ...
Are there any rules/thresholds/Frontiers for epsilons values
I will try with the liquid in and let you know ...

What's your bottle's dimensions? If your objects are small and scene is not big as a 1km. or more, try lower values. For big ranges of scenes, you may need to increase it. That's a treshold factor for lowest values of ray intersections. Because Octane uses floating point math and this is a limit on ranges of dimensions. Think that as a scaling correction factor.

hmmmm, asked the same before, but got no answer to my question.
(Are there some generell tips for settings/values for the "rayepsilon"?)

Hey aoktar

the bottle is 40 cm, real world size...
I think the problem is a backlight situation, I tried a sphere behind the bottle and produces a lot of noise ...I will try in your demo scene with a backlight and your settings ..
