Idea #259: Viewer nodes.

Written by FreeMind the 12 Nov 10 at 01:30. Category: Compositing. Related project: Nothing/Others. Status: New
Rationale
We are required to put viewer nodes into the node editor to see our result! The workflow could be sped up.

Solution #1: A little eye (or whatever icon) button on each node
Written by FreeMind the 12 Nov 10 at 01:30.
Pressing on the eye on the node, makes the node draw its result on the backdrop. It turns off the eye for every other node. Shift-Clicking the icon will select multiple backdrops, same result as Split viewer. The split border should be movable with the mouse.

You can toggle the eye on/off by clicking it, which is identical to Check/uncheck the backdrop checkbox on the header.

Since it's so easy to turn it on and off, we don't need the "Backdrop" checkbox on the header anymore.

The viewer button could also be next to the "image" output handle instead of the nodes header.

You focuses too much on what preview already show.

But what about splitviewer ?
In a viewer node you can connect any socket to it. You can see Alpha, Normal, Shadow...etc.

You won't speed up workflow if you loose comparaison capabilities .

Update!

There is a shortcut already (maybe not well known yet) - add at least one viewer node (this could be included in the default node setup) and ctrl-shift-click on a node to connect it to the active viewer node

yeah, but the viewer node is still there and taking up space.

I'm all for removing the viewer node, its cumbersome.

But I agree with Zeauro that we should not lose the ability to view alpha, normal etc.

FreeMind wrote on the 24 Dec 10 at 06:28
Do alphas and normals have anything to do with the viewer/Splitviewer node?

Wel in the mockup its not clear if you can specify which output you want to view, presumably only the image output. The renderlayer node has 3 ouputs: image, alpha and Zdepth these cannot be viewed in your current proposal.

The ability to view outputs other then "image" is not a feature I would like to lose in favor of your proposal.

Good point.
Few ways to fix this:
1) Connect the Zdepth to a composite node, press the eye on the composite.
2) Selection of what you want to see on the header.

The eye could be selectable next to each output, not the header. This way youcould select either image, depth or alpha or whatever....
