OBS Shader - StreamUP Pattern Tiler

StreamUP Pattern Tiler

Animated tile patterns for OBS. Drop it on a Colour Source, pick a shape, dial the grid. Done.

Starting Soon, BRB, ending screens. Each cell is a dot, ring, star, polygon, line, OBS source, or your own PNG. Add motion. Add hue jitter. Mix two shapes if you want.

Features

• 10 shape types. Dot, ring, square, diamond, plus, polygon, star, OBS source, line, custom image.
• Shape mixing. Two shapes across the same grid, each with its own colour. Set the ratio.
• Aspect presets. Square, 16:9, 9:16, 4:3, 3:4, 21:9, 9:21, plus a Custom option for anything the presets don't cover. No manual masking.
• Grid density. 5 to 200 cells. Anchor to centre, corner, or edge.
• 5 motion types. Scroll, drift, pulse, twinkle, auto-rotate. Stack them.
• Per-cell randomisation. Visibility, size, rotation, hue. Each cell is its own thing, and a Pattern Seed slider reshuffles the whole layout.
• Vignette and cutout mode. Punch holes for reveal effects or fade the edges.
• Edge softness and padding sliders. Tune the look without redrawing anything.

4. Right-click the source, Filters, +, User-defined shader.
5. Point Shader text file at streamup-pattern-tiler.shader.
6. Pick a shape. Dial the grid. Layer your overlays on top.

Patch notes

v0.0.5, 2026-07-23

• The scroll fix. With any Visibility, Hue, Size or Twinkle variation switched on, a scrolling pattern used to glitch on a regular beat. The shapes slid along smoothly, but every few seconds their random identities snapped, so the whole grid flickered as it moved. Sorted now. Each cell keeps its own look as the pattern scrolls, so the motion stays clean however long the stream runs. Static, non-scrolling layouts are untouched.

v0.0.4, 2026-07-06

• The big fix: the pattern kept losing its randomness after the filter had been running for a few hours, so drift, pulse and twinkle slowly fell into sync. Sorted now, it stays properly random no matter how long the stream runs.
• Second colour for the mix shape. The Mix With shape can carry its own Mix Colour instead of inheriting the primary's. Off by default.
• Pattern Seed slider. Reshuffles the whole per-cell layout, visibility, size, hue, drift and twinkle, without touching Density.
• Custom aspect option. Both aspect dropdowns gain a Custom entry with a Manual Aspect Ratio slider for sources the presets don't cover, like 32:9, tri-monitor, or odd PNGs.
• Cleaner edges on non-square grids. Anti-aliasing now accounts for both cell axes.
• Lighter render by default. The 3x3 neighbour path only runs when a shape can actually spill past its cell, so low-density and small-shape setups cost less.

v0.0.3, 2026-05-16

• Aspect dropdowns on the texture shapes. Square, 16:9, 9:16, 4:3, 3:4, 21:9, 9:21. A 16:9 webcam fills its cell exactly. No letterboxing, no squishing.
• Padding slider. Adds a gutter around each shape so they don't sit flush. 0 is the old edge-to-edge behaviour.
• Mix shapes hold their natural aspect. Dots stay round, squares stay square, polygons stay equilateral, even against a wide texture on a non-square grid. Lines still follow the cell shape.
• Use Texture Colours toggle. OBS Source and Custom Image shapes keep their own colours instead of being tinted by Shape Colour. Off by default.
• Settings reshuffled into clearer sections, each opening with a one-line description. Density and Anchors in a Grid section, Shape Mix Amount in a Shape Mix section, Twinkle moved into Motion.

v0.0.2, 2026-05-11

• Configurable density anchor: centre, corner, edge
• Fixed shape clipping at cell edges with a 3x3 neighbour lookup
• Independent hue variation hash so cells re-randomise per frame
• Optimised HSV conversion
