Thank you

Could you send me an example scene? We can then have a look. Thanks.

I can second that, environment medium and lights = noise never goes away, I render 2x or 4x resolution and scale down to get rid of it.

Hi Abstrax
here is the file with noisy medium. It is a max scene. When you start rendering you will see noise never goes away especially near lights where it is the brightest, Maybe you guys can fake it somehow or improve it. Plus volume step length does not work in volume medium

I think future releases should have a real optimized fog system like other renderers have and not just a sphere around your scene with volume texture.

Thank you

Here is a perfect example of this problem, rendering is at 40000 samples alerady and many hot pixels just stay there in the medium, plus the area around the light is super noisy too.
Lw and orbx scenes are attached.

+1 for medium denoising optimisation.

Are you sure that you are using 3.07 test 6, because there was import issue in 3.07 test 5 where Alembic files got imported with the incorrect winding order, which got fixed in test 6. If yes, could you please send me the scene? Thanks.

Thanks for the scene. It seems the normals are exported incorrectly:

Currently, the shadow catcher calculates the shadow it receives on the front face, i.e. the side of which the normal points away. In your case that would be the shadow that is received on the underside of the floor plane.
