Overview
A "knob" node that supplies one numeric value. It is a starting point for routing numbers: distribute the same number to multiple parameters or expose it as a control on a custom node. Because the value is always shown on the node, it can also serve as an in-graph control panel.
Usage tips
- When several nodes share a value such as line thickness or base size, distribute it from one node instead of entering the same number repeatedly.
- Use
range_presetto match the slider range to its purpose, such as 0–1 or a pixel offset. This controls UI ergonomics; actual output limits come fromclamp_min/max, which is separate. - A variable in the Variables panel is better for a project-wide value. This node is intended as a graph-local adjustment knob.
- Use
int_inputwhen the destination requires an integer.
Common pitfalls
- The slider range is not enough: soft range limits only the UI; numeric input can
exceed it. Change
range_presetif you often need a different range. - The value rounds unexpectedly:
stepcontrols snapping. Set it to 0 to disable snapping.
Important behavior
value- With
show_on_node: true, it is always visible on the node itself.
- With
range_preset/soft_*- Normally sets only the operating range of the slider / knob in the inspector.
- Changing a preset immediately clamps the current
valueinto the new soft range. - If Custom Soft Min exceeds Soft Max, the saved values are preserved while the UI uses them in ascending order and shows a warning on both parameters.
clamp_min/clamp_max- Applies a hard clamp to the actual output value.
step- Sets the output snap step.
In short, UI ergonomics and actual output constraints are handled separately.
Usage
- Use
Normalizedfor an immediate0..1value. - Use
PixelOffsetfor an immediate-32..32movement value. - When the destination is a promoted param, use Adopt Target Range in the inspector to match its soft range.
- Tighten
clamp_min/clamp_maxonly when a strict limit is needed.
