Seamless Blend

Node icon
Filter

Makes any image seamlessly tileable by blending the edges using cross-fade or noise-modulated blending.

A texture made tileable by the Seamless Blend node, shown repeated.
A source texture beside the seamless-blended version repeated as a tile with no visible seams.

Seamless Blend blends a non-tileable image’s opposite edges into each other so it repeats without visible seams.

  • Cross-Fade uses a smooth S-curve across the edge region.
  • Noise Blend wobbles the blend boundary with noise for a more organic, less predictable transition.

A wider Blend Width gives smoother transitions but changes more of the original content.

Healing one axis

Section titled “Healing one axis”

The Axes row under Mode picks which seams to heal, on a plain image as on a set:

  • Both (the default) heals left and right and top and bottom.
  • Horizontal heals only the left and right edges and leaves the top-to-bottom profile exactly as it was, so a strip cut for a trim tiles along its length without blurring its top and bottom edges.
  • Vertical heals only the top and bottom edges.

Texture sets and batches

Section titled “Texture sets and batches”

Seamless Blend takes a whole texture set, a library, or a batch: every map is healed along the same seam, and the Normal stays a unit direction. A trim strip from a Trim Sheet usually wants Horizontal.

Check a seam with Offset. Wire an Offset at 50% after the strip and put it in a Viewer slot: the seam that was at the edge moves to the middle, where you can see it, and the blend should make it disappear.

Seamless Blend

ModeChoice
Default: Cross-Fade
  • Cross-FadeSmooth S-curve blend at the edges, clean and predictable.
  • Noise BlendNoise-modulated blend boundary that is more organic, hiding the seam better in natural textures.
Blend Width (%)Number
Default: 15.0 Range: 1.0–50.0

How much of the image is blended at the edges. Higher values create wider, smoother transitions. 50% blends across the entire image

AxesChoice
Default: Both

Which seams to heal

  • BothHeal the seams in both directions. The default.
  • HorizontalHeal only the left and right edges, leaving the top and bottom profile untouched, for a strip that tiles along its length.
  • VerticalHeal only the top and bottom edges, leaving the left and right profile untouched.

Noise Blend

Amount (%)Number
Default: 100 Range: 10–200
Noise Blend mode only

Strength of noise modulation on the blend boundary. Higher values create more irregular seam paths. 100% = default, 200% = maximum distortion.

ScaleInteger
Default: 5 Range: 1–10
Noise Blend mode only

Size of noise variations that modulate the blend boundary. 1 = fine detail, 10 = large, smooth distortions.

SeedInteger
Default: 42 Range: -1–2147483647
Noise Blend mode only

Random seed for the noise pattern. Different seeds produce different blend boundaries. -1 gives each node and each batch frame its own pattern

Usage Tips

Section titled “Usage Tips”
  • Noise Blend hides the seam better on organic textures; Cross-Fade is usually cleaner on photographs.
  • Start around 15 to 25% Blend Width and adjust by eye.
  • Check the result with Tile Preview (T) in the Preview panel, which shows the image repeated in a grid.
