En la mayoria de reflexiones se aprecia, sobre todo en la madera.
Espero puedan ayudarme.

Hello, i'm ready to help, but not sure to understand the problem.. on the rawshadow pass it's hard to see..

Okey, if you extend the photo, you can see little white points that mess my scene. In this two photos can see it.

Still not sure, but in the first photo (rawGI) we can see Irrad.Map splotches.
try the "store direct light" options on/off into SR V2 options panel to see if it helps.. ?

Here you have more examples.
I cant find "store direct light" at SR Options.
I have checked that if I make render with 4000px i have not this problems, or a little. But if I do render approximately with 2000px, i have this problems. Any idea?
Thanks
