This bug is the same in direct lighting and pathtracing kernel. Network rendering I do not use. The last time the settings were:

Here's another strange picture:

Where direct light from portal, noise threshold is not reached for some reason.

This is happening due to Ao environment texture is set to black in the direct lighting kernel and seems to be expected at this point. I need your environment and imager settings to figure out whats happening and will be useful to reproduce it in path tracing.

Thanks

vijay_thirukonda, this happens also with pathtrace kernel, I do not show it because I have only a slow gpu.
There is no error if I disable alpha shadows, the noise threshold is reached first at the light areas of the image as it should be. With portals adaptive sampling does not work properly?
alpha shadows on

alpha shadows off

path tracing kernel:

I think that it should always be, regardless of alpha shadows:

Path tracing kernel alpha shadows off.

Thanks for the scene. Will Keep you posted once I figure out the problem.

"Edit: I have been playing with General Shadow Pass and it is almost bringing tears to my eyes... like an effing dream come true.

This is the shadow pass I have been yearning for!"

yes, same for me without the tears.....

One of the nodes won't authenticate.

How to delete authentication data on a node ? Maybe that will fix it.

I don't get the noise filter on this one.

If you have to lower your exposure in Imager don't forget to also lower the "expected exposure" in Adaptive sampling.
(also why did you remove the render target from the orbx ? was not easy to find back your camera and settings)

Here something that I'm trying to understand since Test 3. Although Every scene is different and so should AS values I got a very easy and little scene were the noise just won't clear easy, Now.. the image is only 5000 samples 2 light sources and it took 37 min to leave it quite noisy and you can see the Noise map a bit empty.

Then without changing the Threshold leaving it at 0.030 I used the Region Render and just after kind of 7 minutes I got so much noise cleared out and wondering why it hasn't detected in the first place not even a bit, region render obviously takes all the power need to quick render up but no noise is detected at 0.010 or should I increase samples at 10000 .. I though that it could kick in and start clear fast..instead I'm curious to get things cleared out on the matter.

edit: Tested at 10000 SAmples AS threshold 0.020 and almost no noise detected from stairs and around the lamp. twice the time and AS did not kick in almost nothin..basically same as 5000 samples.. Pease I really don't get how this is happening. very simple scene just for test but intriguing..
