- Hmmm, how exactly do nodes replace groups of layers? Why would someone use nodes in Blender for grouping elements of e.g. web design? How does it possibly go beyond what GIMP already does and intends to do re layers via GEGL?Feb 23, 2012
- I see the major advantage of Nodes over Layers (even with Groups) as being able to create flexible, non-destructive workflows.
"How does it possibly go beyond what GIMP already does and intends to do?"
For a start, the same image can be used as an input for multiple nodes, and then recombined. Layer Groups are nice, but will still only allow for tree structures. This means that Gimp workflows will still have lots of layer copies, rather than non-destructive references to original images. Some examples of Node layouts can be seen here:

Blender now has a "Group" Node, that allows you to combine a node net into a single container, that can then be used as if it was a single node. Design a button (Or ruler/separator/etc.) image and separate text label images in the "SimpleGimp" app. Then feed the button into multiple Overlay Nodes, with each text label going to a different one of these Nodes. Group each text and Overlay node into Group Nodes. ("Enter Button", "Reset Button", etc.)
Bind the output of each "Button" Node into another Overlay Node (with offsets to handle layout), over the top of a Background Image.
If you want to change the style of the buttons, you only need to edit one Image. In a Gimp layout, you'd have to replace multiple copies of one layer.
To be able to do the same in Gimp, we'd need at least something like a "Reference" Layer (sends the image in one layer to other parts of the tree), which in my opinion, would still be an ugly way to achieve the same thing as a Node Editor.Feb 23, 2012

- In other words, layers and nodes don't need to be mutually exclusive. Both have benefits.Feb 23, 2012
- "Are you familiar with ..." I am, but realistically that's several years in the future.
Currently what everyone is waiting for is high colour resolution - so we can finally shut those Photoshop Fanboys up. ;)
Don't get me wrong, I love GIMP, it's still faster than Krita on my laptop, but the instant it can support high-colour, I'm noding it up in Blender.Feb 23, 2012
