Hey, I noticed something.
If you enable render layer and want a reflection pass rendered out there is no way to tell how many samples the reflection pass should have.
My scene has 3000 samples set up. (Using Render Region and Adaptive Sampling). However while the main pass is being rendered noise-free the reflection pass of the render layer is not getting noise free at all and I also noticed that it just renders for 1-2 seconds while the beauty renders over a minute. So something doesn't add up there. It FEELS like the reflection pass only is rendering 128 samples or something.
You don't see any render info when the layer reflection pass is being rendered so you cant really say what is happening.
Layer Reflection never noise-free

Hi Dino! Is it better on standalone? As you may know this is not a plugin based issue.

I'm currently facing the same problem. I'm trying to render out a reflection pass by turning off the visibility of my object and only getting the reflections of it in on the ground. It works just fine, except the fact, that the reflection pass stays noisy, no matter what sample count I use.
Is there a solution for this? I'm running the latest stable and can't really test it in standalone since I've no idea how it works.

Thanks for your reply. Unfortunatley I can't share the scene due to commercial restrictions of the project. Right now I can't provide a simple replica of the scene either because all my workstations are rendering.
But its actually quiet simple:
My object is placed on a shiny ground, to have more control over the reflection I disable the object via the camera tag (camera visibility turned off), enable multi pass/Reflections and save it seperatley.
Kernel is set to PT, 5000 samples (which clears the image completely in Beauty).
But I still get noise like in the attached image.
No matter if I increase the Kernel samples or the Info Layer samples in the multi pass settings.

Hi,
without the scene I can only guessing, but note that there are two different Reflections passes in the Render Passes tab:
The first one is related with the beauty passes, and needs to be mixed/layered with other layer passes to obtain the original beauty pass, so even if some residual noise is visible, it will be cancelled when layered in compositing:

The second one is related to the Render Layer technique to isolate bauty, shadows and reflections of an object in a scene:
http://www.aoktar.com/octane/RenderLayer.html
Which one are you actually using?

So im having the same issues here when using the render layer with the Blackshadow option. Im rendering with path tracing and iam using 4069 Samples to get a noise free Beauty, but my Render Layer Blackshadow is very noisy. Anything i missed?

Please share a scene that shows the issue.
As said, we cannot reproduce it here with our scenes, so we need a clear example to better investigate, thanks.

oh damn I am having this exact issue with aov render reflection pass.
Is there anyway to fix this?

there is a vdbvolume behind the balcony and when I turn the vdb off then the noise, aislising goes away.
Not sure how to solve it. I need the vdb volume tbh.
