Compositor - ID Mask Anti Aliasing not working #49944
iMac Retina Late 2015
OS X El Capitan
Anti Aliasing in the ID Mask Node doesn't work anymore.
Left side: Blender 2.78a Right side: Blender 2.76
This was an intentional change in
feb574f. The issue was that adding two masks did not give proper full coverage of the image causing compositing artifacts.
However, here it seems there is no AA at all (hard to tell from just seeing the image). It might or might not be a real issue here.
This is why it is always important to attach .blend file which demonstrates the issue.
Here's the blend file
Ok, there is AA in the mask, but it seems to be not enough to give smooth edges. Will try to tweak some parameters to solve both of this problems..
Any news here?
I can confirm that although anti aliasing works, it was much better before.
This is a know issue, a limitation of the current alias algorithm/implementation.
We currently have the AA node. From workflow point of view masks can be added and AA afterwards.
For more complex setups use Cryptomatte.
My proposal would be to use the SMAA operators for AA in ID Mask with the default settings. How to use these operators can be found in
