And Frank, you just bring in a clip from the Clips menu in the FxTree.
It works great, however, in this case, we're bringing in rendered
data, whereas a clip has to be sourced from an image somewhere.
If someone could do a plugin that can output the realtime-rendered
result of something (almost like the camera's rendered view of said
data) on screen and have a "magical" image clip that we can take to
the fxtree and modify said clip.
Kinda like doing your own custom post effects that would run right
after the render is done, using the render's data as part of the
magical imageclip.
