Node controls
Bypass, Solo, Strength, Opacity, colour, name and size: the flags every node carries.
These controls sit on the node body or in its right-click menu, and they behave the same on every node.
Bypass (B)
Bypass turns a node off without deleting it. A bypassed node passes its input straight through untouched. A generator with no input, such as a Circle, produces nothing.
Right-click the node and choose Bypass, or select it and press B. Toggling it is the clean way to A/B an effect.
Bypassing changes what flows downstream, so the graph re-cooks and the viewport updates immediately.
Solo (S)
Solo makes the viewport show one node's output instead of what would normally be the final result. It reads an intermediate step deep in a graph without rewiring anything.
Right-click and choose Solo, or press S. Soloing a different node moves the spotlight; clearing it returns to the graph's normal output.
Walk Solo up the chain node by node to find the exact point where a result stops looking right.
Strength
Every visual effect carries a strength, the wet/dry amount, from 0 to 1 and starting at 1. Right-click and choose Set Strength... for a slider, or drive the strength parameter like any other: it is keyframable and wirable.
At an intermediate value the executor blends the node's output with its first connected input, so half strength is a half-applied effect. At 0 it takes the same pass-through path as Bypass, which is why Bypass is the flag and strength is the dial. The two are independent, so a bypassed node stays bypassed whatever its strength says.
Opacity
Nodes that produce visual content, rather than change it, carry opacity instead, also 0 to 1 and starting at 1. Lowering it fades that node's contribution into whatever sits behind it in the composite, and the viewport recomposites as you drag. The Layers panel carries an opacity bar for every row, generators and effects alike. For how nodes stack and blend, see Layers & compositing.
Opacity is also the visibility control
Exactly 0 is a hide rather than a fade, and it is how the graph decides what draws. Wire a node into something that consumes its visuals and that node's opacity is set to 0 for you, so the ingredient stops drawing behind the result. Drag it back up and the node draws again alongside its consumer, which is how you get both on screen. Cutting the last such wire puts the opacity back to 1, so an in-between value you had set by hand before wiring does not survive the round trip.
There is no separate eye toggle and no badge on the node. The opacity value on the node body, and the matching bar in the Layers panel, are the whole of it, and the Layers panel deliberately keeps a row for a node sitting at 0 so there is always something to drag back up.
A node hidden this way is dropped from the live viewport only. A capture or an offscreen pass that reads it still renders it, and renders it at full opacity rather than at 0, so a hide never darkens anything downstream. For a genuine near-invisible fade, use a small value such as 0.005 rather than 0.
Opening a project saved before this behaviour existed shows exactly what it always showed. What changes is that its consumed nodes now read 0 on the slider instead of 1, so the state you could not see before is there to drag.
Colour and family
Nodes are tinted by family, one of Generate, Modify, Data, IO, Structure or Plugin, which is what makes a graph readable at a glance. See Node families & graph colours. Right-click and pick one of the 14 preset colour swatches to override a node's tint, or choose Reset to Family Color to drop the override.
Colour is cosmetic. It never changes what a node does.
Rename and resize
Double-click a node's title and type a new name, then Enter to commit or Esc to cancel. Clicking away commits it too, and typing the node's own type name back in clears the override. A name like Lighting or Hero Text beats the default node type once a graph grows.
Drag one of a node's four corners to resize it. Larger nodes are easier to read when you have pinned controls or want a parameter visible on the body. Widths snap to a column grid, and double-clicking the edge resets the width.
Renaming, recolouring and resizing are layout-only. They do not affect the result and cost nothing at cook time.
