Hi guys,

Sharly, I´ve watched your video (https://www.youtube.com/watch?v=2zkuYjFghJ8&t=1s) and you answered somebody saying that you have used 300 samples per frame. I´m working on an animation which, in my tests, using 800 samples in a resolution of 2200x800 pixels, it´s not perfect. The secret should be Light Importance correct setup?

The first noise killer is clamping : use as low clamping as you can afford ( without to much darkening or highlight lost).
Use also low light path bounce if possible.
A good lighting is important ( noise mean mostly light harder to sample or not enough).
Avoid combination of sharp sun shadow on highly reflective floor it lead to lot of unresolved caustics.
If you work with artistic value for light and linear for camera a clamping of five is just enought.

Thank you, Sharly!
What "Use also low light if possible" mean?

One of the rooms, is lighted by 4 small mesh light on the ceiling. The effect was unrealistic. I changed to a big area light, which gave me a better result.

Low light path bounce i mean. It is corrected thanks.
For small mesh light. Maybe you want to simulate artificial light.
On my side it work seamlessly. The secret is to use a mesh light with very little number of poly. Or just use a point light with an IES profil it is faster if i remenber well.

Thanks, Sharly! I´ll make some tests.

Thank you for your advices.

Would be great to have a detailed tutorial on how to do a walkthrough animation and the usage of the cache feature. I could have an amazing oportunity of using Lux for a walkthourgh animation right now, but the lack of documentation and tutorial about this topic is minimal so I had to decided not to use it, sadly.
