Rendering noise issue

[maganiacc]

Hi All,

 

This is my first post and i want to share something that happens to me in almost all my renders....

 

I usually render with irradiance map and light caché GI and in any material with any kind of reflection always makes some noise on the shadows, ¿How can i fix this?

 

An example;

 

 

Thank in advance, lot to learn here!

Looks like an image sampler issue. Please post settings of it.

In the VRay tab change the image sampler type from Adaptive DMC to Adaptive subdivision and and below that, set the min rate to something like 0 or 1 (for really high quality you can set to 2 but i think its not necessary), set the max rate to maybe 3 or 4 and set the noise threshold to something like 0.002-0.006. You can increase the light and shadow subdivs, increase the DMC sampler min subdivs a bit and the HSph subdivs too to something like 70-80 and i don't recommend using Catmull-Rom as the AA filter. First I would just change the Adaptive DMC to Adaptive subdivision and set the min rate to 0 and the max to 2 or 3, and see if it gets better. I hope it helps.

If it's not good enough or the rendering takes to long, either way just change the numbers.

You can also just increase the Shadow Subdivs on your light source.
