Noisy CShading_shadows pass

Corona Corona for 3ds Max Help Required

Hi, I picked up Corona this weekend, and am really liking so far.

I was playing around the the sample scene and noticed that the Shadows render element is giving me a lot of noise. Just wondering what might be the cause? Because the Beauty pass is practically noise free. Ignore the stamp at the bottom, this is actually after 200 passes.

I also noticed that the RawComponents pass has similar noise issues. Any ideas?

It is normal - corona samples to make beauty pass clear, not shadows/raw. Sampling to make those passes clear fast would decrease performance for beauty pass

Ah ok, that makes sense. Thanks for the reply
