Hi, as already mentioned, adaptivity is not intended to speed up rendering. It just makes the noise distribution more uniform.
Here are some examples: https://coronarenderer.freshdesk.com/support/solutions/articles/12000004975
In the first example with the glasses you can see that the DOF areas got much better, but that's "at the cost of" some uniform areas which were slightly less noisy with adaptivity disabled.
In the last example you can see how much adaptivity changes when using denoising with it. Disabling adaptivity would sometimes lead to situations like this.
1.4 adaptivity is not infallible, but it is definitely better than no adaptivity at all.
Hello guys,
I would like to know what happens "under the hood" that adaptive system on Corona.
I don´t have technical knowlegement, but after watched a video that shows how adaptive works on Fstorm I thought they has different methods.
e.g fstorm´s sampling method stops to sampling areas that doesn´t need more sampling and keep focus just where it´s needed.
Corona´s sampling works that way too?
Thanks and sorry my english if it´s not clear enought.
