Clean Beauty-pass, but super-noise in Refraction-pass..

Corona Corona for Cinema 4D Help Required

Hi,

I’ve rendered a transparent product with some water liquid inside. The Beauty-pass is very clean at 1,65% ‘Noise Level’, but the ‘refraction pass’ (that I want to use in post) is still super noisy. I haven’t used any bump or surface textures at all for attached screenshots. Any ideas what is wrong?

Thanks
Frederik

Are you able to share your scene with us for testing?

Hi! Sorry for late reply, but I found the error. It was checkbox for antialiasing (in the multipass) that was disabled. Checking this then everything looks good.

Thanks
