Denoising Issues of Intel CPUs in Corona 13/14 on macOS and Inquiry About Fix

[CR_love]

On macOS systems, neither Corona 13 nor 14’s denoising mode supports Intel CPUs. Moreover, the noise reduction quality and speed of Corona’s High Quality mode are inferior to those when using Intel CPUs, with anomalies at edge details being particularly noticeable. Could you please let us know when the denoising issue for Intel CPUs will be fixed?

The CPU version of the Intel AI denoiser should work on Mac OS regardless of CPU model. Can you explain what exactly you mean by "neither Corona 13 nor 14’s denoising mode supports Intel CPUs"? Are you getting some error message? Or perhaps the denoiser doesn't work at all?

Regarding the Corona HQ denoiser, what you see is not an issue specific to Intel or other CPU models. It's just how this denoiser works. It's inferior to the AI denoisers - I wouldn't recommend using it.

Yes, when selecting the Intel denoiser, there's absolutely no response at all.

For interactive or production rendering?

Hi Maru,
The problem occurs during production rendering. The Intel denoiser works as expected on Windows (with the same Intel CPU), but on macOS, selecting the Intel denoiser doesn't work at all.

And once you stop rendering, the Intel denoiser effect isn't applied either? (sorry, just making sure that I understand this right)

Yes, that's right.

Hi Maru,
Previously, someone encountered the same issue as me.
