Generic filter

A generic effect will be applied on all the document channels, including opacity. A generic filter can be :

  • grayscale, it will be applied to each component (R, G, B and A) of each channel (basecolor, metallic, roughness and so on)
  • color, it will be applied on colored channel as-is, or converted to grayscale internally to affect grayscale channels

The input node of the effect must have the identifier or usage defined input and its output node must have output. Note that color based fitlers can't be used on the mask of a layer, only grayscale fitlers will be compatible.

It is possible to use either the usage or the identifier in an input node (the usage has the priority).
