Noise in shadows

Hello!

When I’m using bright colors there is too much noise in shadows. It’s not going away even after 80 passes (1:30:00)

In condition of white color it goes away much faster 30-40 passes

PTS 32 MSI 20

and albedo? Do you use it?

try using HD cache + 8-12 pts
and reflection value ? is it too high ?

Thank you, guys. I tried but have no success. Here the scene, even without textures it has awful noise in shadows.

HDCache bad working on crop or region. You need test it in "view’ mode

Really ? Is this some bug or something ? Because I wondered why the “crop” renders sometimes shut down my 3dsMax during HD or before, but never anytime else.

Tests in view mode.



what is your light source ?

Sky + Sun + Portal

Tried to lower MSI (to 2). It solved the problem particulary.

Lowering sun intensity to 0.2 and MSI to 10 helped a lot.
