Descripción
Limn PRO Outline and Highlight System
Outlines with motion, patterns, 27 shader effects and x-ray for Unreal Engine 5.7. Everything in Limn Free included.
imn draws outlines from a jump flood distance field, a true distance from the silhouette for every pixel. That distance is what makes the effects possible: bands at any width, glows without blur steps, rings that travel outward, lightning that runs along the contour. Limn Pro is the complete plugin. You do not need Limn Free next to it.
What you get
- Limn Outline component with persistent, hover and select styles.
- Limn Interactor component: the player's look trace highlights interactable actors, local player only.
- Request stack with priorities and timed requests.
- Glow, additive or laid over the scene.
- Same look on every screen, widths shrink with distance, outlines stay behind walls.
Motion and patterns
Add Pattern and Motion (Pro) to any style.
- Pulse and breathe, with a per object phase so a group does not blink in lockstep.
- Dashes and flow along the contour. A marching ant selection is two numbers.
- Wobble, smooth or redrawn in steps like hand drawn animation.
- Band layouts: gradient, two tone sticker edge, double line, contour rings.
- Reveal by progress: the outline becomes a progress ring for capture points, timers and channels. Drive it from Blueprint with Set Outline Progress.
27 shader effects
Add Effect (Pro) to any style and tune Speed, Scale, Amount and Angle.
Electric Arc, Glitch, Sonar Rings, Iridescent, Echo Trail, Heartbeat, Ink Bleed, Circuit Trace, Risograph, Halftone, Data Stream, Shatter, Heat Shimmer, Plasma Flow, Void, Frost Crystals, Pen Trace, Blueprint Build, Scan Reveal, Contact Spread, Countdown, Damage Direction, Proximity Draw, Inner Carve, X-Ray, Hologram, Sheen.
X-ray
Parts of an outlined actor hidden behind walls show as a hatched silhouette. Everything else stays behind the wall as in Limn Free.
Gameplay tag rules and transition curves
- A rule set picks the style from an actor's gameplay tags, so a looted chest or an alerted guard changes its outline on its own.
- Transition curves shape how one style blends into the next: ease out, ease in out, overshoot or your own curve.
50 presets
The 6 Free presets plus 44 more: quest breath, pickup pulse, ghost, dashed door, gradient fire, sticker, topographic, progress ring, loot rarities, danger stripes, and one preset for every effect. Duplicate any of them as a starting point.
Performance
- 0.00 ms when nothing is outlined: no pass runs at all.
- The effects pass runs only in views that can see an object with an effect.
- About 0.11 ms for five effects at once, among them Glitch and Hologram, measured at 1280x720 on an RTX 5070.
- limn.ReduceFlashing turns off anything that cycles faster than three times per second, for players sensitive to flashing.
Requirements
- Unreal Engine 5.7, Windows and Linux targets.
- Project Settings > Engine > Rendering > Custom Depth-Stencil Pass: Enabled with Stencil. Limn logs a clear message if it is off.
- Shader Model 5 or newer (DirectX 11 or 12, Vulkan). Not for mobile.
- Outlines are drawn per machine and are not replicated. In multiplayer each player's interactor highlights only for that player.
