Node A is needed to view the rendered result.

Node B is used to separate and store the rendering result.

thanks kim, i dont want to view it,

i want to save the compositing result. BUT if you render a frame you will see the compositing result transparent in rendering. and that is what gets saved.

so, why is it transparent and also with no content?

  1. Determines the output path of A.
    A will save the rendering image (Group Output required)

  2. When you create File Output, it is set to A setting and the node is configured.
    You can separate by specifying additional passes in File Output.

I don’t know if the explanation is understandable (language issues, not English speakers)
