RedNode Stage View

RedNode Stage View is the panel that makes Stage Tap worth placing: it shows every tap from the last run in order, and lets you drag a wipe across any two of them to see what changed. You tap stages anywhere in the graph, run once, and the view is your before/after slider into your own pipeline. The taps find the view and the view finds the taps - no wires, no Set/Get pairs, nothing to redo when the workflow changes.

This is the payoff half of the Studio's stage system. The taps are cheap and transparent - they photograph a moment and pass data through - but on their own they're just records. The view is what makes them useful: instead of eyeballing two preview images and trying to remember what the upscale actually did, you drag the wipe and see the difference slide across. It's the difference between debugging by memory and debugging by comparison.

How it works

The view reads the same in-memory store the taps write to - the wireless pattern the pack uses throughout - keyed to the last run, in the order the taps executed. Every Stage Tap in the workflow appears as a step, numbered or labelled, and any two can be selected for the wipe. Because it's reading what the taps recorded, it works whether you have two taps or twenty, and it never needs you to reconnect anything when you move a tap in the graph. It's an output node, so it runs when the graph reaches it, and it has no inputs or outputs to wire.

Using it

• Place a RedNode Stage View on the canvas.
• Drop RedNode Stage Taps at the moments you care about - before the detailer, after the upscale, at the VAE decode - wiring each one's output onward.
• Run once. The view lists the taps from that run in order.
• Pick two steps and drag the wipe across to compare them.

The label on each tap is what makes the strip readable, so name them ("after upscale", "post-grade") rather than relying on numbers. Taps only remember the last run - the view is a fresh snapshot every queue, which is exactly what you want for iteration and exactly not what you want for archiving.

The honest take

The wipe-compare is genuinely nice - it's the kind of tool that makes you notice things you'd never catch flipping between two whole images. The limitations are the standard wireless-store ones: it's last-run-only, and it only shows what taps you placed. No taps, no view. Place the taps inline (outputs wired onward) or they won't execute, and the strip will sit empty while you wonder where your stages went. Used properly it turns "what did that step actually do" from a guess into a drag.
