Masks not denoised - a few bugs

[Micha]

Attached an image of a denoised material ID (GPU mode). The blurry area caused by DoF isn't denoised. I suppose so the problem is that the denoised alpha isn't used. In CPU mode the material ID base on a denoised alpha and looks ok.

The multimatte object ID color outputs are not using any denoising in CPU and GPU mode.

Hi Micha


Apologies for the delay.

From what we've tested, Material ID RE should have no differences both on CPU/GPU mode; see screen recording: http://ftp.chaosgroup.com/support/sc...9_19-10-53.gif
Depending on the RE used, you may want to enable the Denoise parameter within the element (e.g. for Material ID Color).

Do forward a sample project file so we can compare results and see if we can reproduce those differences. Thanks!

Hi nikoleta.garkova,

attached an example file. Please start a rendering and look at the blurry edges at 400%.

GPU:
- denoise beauty shows noisy edges
- mat random color shows noisy edges
- multimatte object ID complete without denoise
-

CPU
- denoise beauty is ok
- mat random color ok
- multimatte object ID not ok

It looks like the noisy edges are cause by a weak denoising of the dark areas of the alpha in GPU mode. The multimatte object ID seems not to support denoising, but so the results are not right usable.
