Splotches, Blotches and Light Noise "Oh My"

For those of you who have had issues with light noise, in the form of those dreaded splotches and blotches, I have posted a blog (bedtime story) here...

Enjoy

  • Hi Alex,

    I know what is causing this, it is the shadow sampling on your area lights. Using soft very fine (256 samples) will help. You can see this yourself by setting the shadows to coarse (16 samples) which will produce the most noise.

    I would be happy to take a look at your test case too ;-) I might be able to come with some ideas if I had your scene. I suppose we could allow even larger sample values to be used which would eliminate the noise. I'll talk to Paul maybe we can get this into the update.

    Regards,
