Quick Outline Pro

Put one component on a character and it reads at two metres and at fifty, holds its thickness in pixels while the camera moves, and switches to a second colour the moment something comes between it and the camera.

That last part is the whole point: the same silhouette, two colours, split exactly where the wall is. It is the look every extraction shooter, every co-op teammate marker and every "your target is through there" uses — and it is one dropdown here.

Two techniques, four ways of handling walls, six animations, three render pipelines. And when nothing is outlined, it costs nothing at all: no full-screen pass, no material swap, no per-frame allocation.

TWO COLOURS, SPLIT AT THE WALL

• A depth-independent stencil mask stamps the silhouette first, so the hidden half really is the hidden half — not a filled ghost bleeding over the cover

• Four modes: visible only, second colour, x-ray silhouette, always on top

• The x-ray fill has its own opacity, so it hints at a position instead of becoming a wall of colour

TWO TECHNIQUES, ONE COMPONENT

• MESH HULL — one extra draw per renderer, no full-screen work, and nothing at all while nothing is outlined

• SCREEN SPACE — identical thickness on every shape, no baking, and a separable edge detect that costs 34 samples per pixel at radius 8 instead of 289

• Switch on the profile. Nothing else in your scene changes.

THICKNESS THAT BEHAVES

• World units, screen pixels, or world units clamped to a pixel range so a corridor's far end never turns into a hairline

• Worked out PER CAMERA — the Scene View, a split screen and a render-texture camera each get their own correct number instead of inheriting Camera.main's

• Distance fade that drops an object before a single draw call is made

BUILT FOR CROWDS

• Colour and thickness can be overridden per object without a second profile

• Both ride in the property block the outline already fills in, so a hundred enemies in a hundred colours are still four materials, not four hundred

• Hide an outline and the materials come straight back off the renderer

SIX ANIMATIONS

• Pulse, blink, wave, colour shift and scan

• Colour shift and scan run per pixel on the GPU and cost the CPU nothing — and the inspector tells you which of the two any setting uses

• HDR colours above 1 are picked up by bloom, which is how you get an outline that glows

A BAKER FOR HARD EDGES

• An inverted hull tears open at every hard edge, because a hard edge has several normals. One click bakes averaged normals into UV3.

• Your imported mesh is never touched — a copy is written next to it

• Meshes with no project folder of their own go to a Baked folder instead

• Not readable? The inspector says so and points you at the screen-space technique, which needs no baking at all

INSPECTORS THAT EXPLAIN THEMSELVES

• Every choice is a row of buttons with a sentence saying what the selected one actually does

• A live picture of the outline in its real colours, at roughly its real thickness

• Measured readouts: distance, thickness in pixels AND world units, opacity, extra draw calls

• A check panel that names what is wrong — missing profile, a mesh that will tear, a screen-space profile with no hook in the renderer — and offers the fix inline

IN THE BOX

• A ready demo scene at Assets/QuickOutlinePro/Demo, with four procedural figures, built from primitives — no models, no textures, nothing to break on upgrade

• Six presets: Selection, Hover, Enemy, Ally, Interactable and X-Ray

• A setup window that detects your pipeline and installs the screen-space hook for Built-in, URP or HDRP in a click

• Full C# source, README and changelog

NO DEPENDENCIES

Not "no third-party dependencies" — no Unity packages either. Nothing to install, nothing to import, no TextMeshPro, no uGUI. The URP and HDRP folders only compile when those packages are already present, so the package imports into a bare Built-in project with zero errors.
