Lines
Procedural line-set generator
Generates one or more line sets with animated start/end states, spacing, thickness, dashes, softness, color and overlap controls.
This tool belongs to the Krokodove set integrated into DaVinci Resolve 21 and Fusion Studio 21. See the complete Krokodove node list and the comparison with native Fusion tools.
Lines
DaVinci Resolve · Fusion
Lines is a procedural line-graphics generator for HUD elements, scan lines, technical overlays, animated strokes and repeated design accents.
Overview
What Lines does
First and Last define two independent line states. Fusion can interpolate between them over time, making Lines especially useful for controlled procedural animation.
Spacing, thickness, dot spacing and softness define the graphic language of each state, while Number Of Line Sets and Overlap determine how multiple sets combine.
Render and Image controls matter for fine line work because undersampling quickly creates flicker or aliasing.
Mental model
Think of Lines as two keyframed procedural line designs: First is the starting look, Last is the ending look, and Fusion generates the in-between line field.
Common uses

Important parameters
Start with these controls before reaching for more complicated workarounds.
First: Center 1 X/Y
Sets the X/Y coordinates for First: Center 1.
First: Angle 1
Sets Angle 1 for the first state or pattern.
First: Spacing 1
Sets Spacing 1 for the first state or pattern.
First: Thickness 1
Sets Thickness 1 for the first state or pattern.
First: Thickness Scaling 1
Sets Thickness Scaling 1 for the first state or pattern.
First: Softness 1
Sets Softness 1 for the first state or pattern.
First: Softness Increase 1
Sets Softness Increase 1 for the first state or pattern.
First: Dot Spacing 1
Sets Dot Spacing 1 for the first state or pattern.
First: Dot Length 1
Sets Dot Length 1 for the first state or pattern.
First: Length Scaling 1
Sets Length Scaling 1 for the first state or pattern.
First: Dot Softness 1
Sets Dot Softness 1 for the first state or pattern.
First: Dot Softness Increase 1
Sets Dot Softness Increase 1 for the first state or pattern.
First: Color 1 / Red / Green / Blue / Alpha
Provides separate controls for the red, green, blue and alpha channels.
Last: Center 2 X/Y
Sets the X/Y coordinates for Last: Center 2.
Last: Angle 2
Sets Angle 2 for the second/final state or pattern.
Last: Spacing 2 / Thickness 2 / Softness 2 / Dot Parameters
Sets Spacing 2 / Thickness 2 / Softness 2 / Dot Parameters for the second/final state or pattern.
Last: Color 2 / Red / Green / Blue / Alpha
Provides separate controls for the red, green, blue and alpha channels.
Options: Number Of Line Sets
Sets Options to Number Of Line Sets.
Options: Overlap — Maximum
Sets Options to Overlap — Maximum.
Options: Overlap — Add
Sets Options to Overlap — Add.
Options: Overlap — Multiply
Sets Options to Overlap — Multiply.
Options: Overlap — Screen
Sets Options to Overlap — Screen.
Render: Super-Sampling
Sets Render to Super-Sampling.
Image: Process Mode
Sets Image to Process Mode.
Image: Width / Height / Auto Resolution
Sets Image to Width / Height / Auto Resolution.
Image: Pixel Aspect X/Y
Sets the pixel aspect ratio.
Source Color Space: Color Space Type
Selects how the source color space is specified.
Source Gamma Space: Curve Type
Uses Curve Type for source gamma space.
Remove Curve
Removes the selected gamma or transfer curve so the source is treated in a linearized form.
Pre-Divide / Post-Multiply
Controls premultiplied-alpha handling around the operation.
Pre-divide removes alpha multiplication before processing; post-multiply restores it afterward. This is useful when color work creates dark or bright fringes around translucent edges.

Troubleshooting
Common mistakes
Using lines thinner than the output can resolve
Combining many additive sets and clipping highlights
Ignoring supersampling on rotating patterns
Production notes
Practical tips
Animate First-to-Last rather than keyframing every line property independently.
Use a low-alpha glow for electronic UI looks.
