Title: Ｄifference between "Cmasking_ID" and "Cmasking_Cryptomatte"
Post by: hiramiya on 2023-03-28, 17:49:07

What's the difference between "Cmasking_ID" and "Cmasking_Cryptomatte" in RenderElements?
While both can be separated by color information, which one is superior?

The color information seen in Cryptomatte is NOT the Cryptomatte but just a handy human-visualization. See

So the difference is:
- Cryptomatte accounts for depth of field and motion blur, while the other masks do not. Only use Cryptomatte if one or both of these are an issue.
- Cryptomatte is comparatively difficult to set up the required post processing, while the other masks are pretty straightforward.
