Overview
A streak along an angle: speed lines, faked motion on a still. Centered, energy-conserving; MotionBlur is the temporal shutter, this is the spatial one.
How to
How-to
- Set
angleanddistancein pixels; the streak is centred and energy-conserving. - Use it for speed lines or faked motion on a still; for real per-pixel motion use MotionBlur or VectorBlur.
Inputs
| Input | What it takes |
|---|---|
| in | the image this node works on |
| mask | limits the effect to this matte — the engine's universal mask slot, applied for every node that declares it |

Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| channels | Choice | rgba | Which channels this node writes: rgba, rgb (alpha passes through untouched), alpha only, all, or none (bypass). Everything unselected comes straight from the input — same as Nuke. allrgbargbalphanone |
| angle | Float | 0.0 | Direction of the smear, in degrees. |
| distance | Float | 10.0 | Length of the smear, in pixels. |
| disabled | Bool | false | Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back. |
| label | Text | A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache. | |
| hide_input | Bool | false | Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap). |
