High Levels of noise in Specular Glass object.

[GSMATTAnimation]

Hi All,

I wonder if anyone can help me out regarding the image attached. As you can see that the glass on the edge is extremely noisey.
Looking at my render settings I can I can't figure out what I can do to reduce this noise. This one frame from an animation.
Let me know if there is anything else information wise.

Look forward to your help.

Cheers.

I think you need more samples. In my experience, glass or any kind of hyper-reflective/refractive material needs wayyy more samples.

If you're on Octane 4, you should use the denoiser too. It might smooth things out enough so any remaining noise gets lost in the motion blur.

Also look into using the PMC kernel. I think it's specifically built for that sort of thing.
