Ive set up an animation for a product that has a transparent lens and optics.
I just cant seem to get rid of the noise when I render!
This is in Accurate mode with 1200 passes.
This is in Fast mode at 400 DPI....
I feel like Im missing something obvious.
Im working with an NVIDIA M4000, so no denoiser option available for me :-(
Hello Kristen!
Andreas is correct... Your GPU should support the Denoiser. You may need to initialize and enable the button first. Make sure both check boxes in "Tools > Options > 3D Viewport > Denoiser" are checked!
What version of Visualize are you using?
Bastian - Im using Visualize 2018 Pro.
Not sure why, but there is no option for denoiser. 
Hi Kristen. The Denoiser was only released in 2018 SP2. You may be using an earlier version of 2018 (see Help > About) and may need to upgrade to a later service pack!
Thank you very much for the advice. I'll have to double check on the denoiser. I didn't see an option for it so assumes my card wasn't substantial enough.
Hi Kristen,
An other information may help you when you will using right SW version.
With an M4000 you will need to setup the rseolution lower than the maximum.
Hope that will be helpful
Hi Kristen,
Without denoiser you can't do much else but increase your pass count.
But you say you're using a NVIDIA Quadro M4000?
I'm using that same card and I can use denoiser without any problems.
