Hi max_romju,

The denoiser slider only works for the viewport and has no effect in High quality snapshot and High quality sequence. It can be either on(100) or off(0) for that. You could try to make screenshot without denoiser after a certain amount of passes and then make another one with the denoiser on and combine then in post. We will look into ways to increase image sharpness with the denoiser enabled and inform you when there is something.

Best regards,
Alexander

thanks ,I will have a try

To clarify a bit further: The slider controls how much to blend between the raw (noisy) image and the denoised version of it. Notice that it does NOT control the strength of the denoiser (i.e. how much it blurs), for either of the two denoisers. The slider had some use with the Vantage denoiser, but with the NVIDIA denoiser it is pointless as it just adds noise when set to less than 100. We are probably going to change the UI in a future version because of that.

Are you sure this is caused by the denoiser ?
The difference to V-Ray could be caused by a difference in how bump maps are rendered in Vantage.

Hi Vladimir , High quality snapshot setting like picture ,on/off denoiser.so I think the denoiser influence on detail

[max_romju]

by the way ,when I render 4k snapshot, even turn on denoiser ,the detail is fine

It looks like the blurred surface has strong bump mapping that changes pretty much every pixel. This makes it harder for the denoiser to "decide" what to do there. This is why rendering at a higher resolution is better because the normals don't change so much with every pixel.

I think there are two options for you: either render more samples (the screenshot shows just 100 samples) or render at a higher resolution and downscale the image to your desired/intended resolution. Whichever achieves the desired result faster.

[max_romju]

render big to downscale is ok,Tnaks
but set high samples doesn't work,I post the texture.you can reset the material to have a test.
