Particles Ghost Mesh

LIVE WEBGL DEMO also on my site main page

Turn your mesh into a ghost, a hologram or a cloud of drifting embers.

 Bake a static prop and it becomes a self contained point cloud. Bake a rigged character and the cloud dances with any Animator, throwing sparks behind every moving limb. The baker converts geometry into a point cloud stored in two compact textures. 

A static cloud does not reference the source mesh, so the model can stay out of the build entirely. Any mesh you can import is a valid source, from a single prop to a whole environment hierarchy or a character. That is how you get dancing spirits and apparitions, holographic UI and sci fi scanners, dissolve and respawn transitions, logo intros, data visualization and landing page scenes, all from models you already have in the project.  

At runtime the cloud is one mesh and one material. There are no compute shaders and no GraphicsBuffers anywhere in the pipeline, skinning included, which is why it runs in a browser tab and on a phone where compute based particle systems refuse to start.

★ URP, HDRP AND BUILT-IN ★

 One package for all three render pipelines. Every shader carries a SubShader per pipeline and Unity picks the matching one automatically. Demo scenes are included for each pipeline, including a dancing character scene.

★ BUILT FOR MOBILE AND WEB ★

The simulation is a fragment shader blit on a pair of ping pong render textures.

Shader target is 3.5. That keeps the asset compatible with WebGL2, WebGPU,

Android and iOS, where compute based particle systems simply refuse to work.

Point size is clamped in pixels, so a 160k point cloud stays readable and cheap

at any resolution and on any screen.

★ ANIMATED GHOSTS ★

Drop a character with a SkinnedMeshRenderer into the baker and you get a cloud plus a skin asset that binds every point to its bones. Assign the animated character as Skin Root and the cloud follows clips, blend trees and Timeline with no code. The trail system records 32 frames of bone history, so sparks follow the real past path of each limb, cool from hot to cold color and fade. A still body leaves no trail.

★ ONE COMPONENT, SEVEN SYSTEMS ★

Pointer repulsion, wind, flow, spark trail, HDR gradient, material palette tinting and self occlusion, all from one Liquid Mesh Particles inspector. Every system is independent and switches off from a single field, with no shader variants per system.

★ A REAL BAKER, NOT A RANDOM SCATTER ★

The Point Cloud Baker merges every MeshFilter under a source object, welds

coincident vertices, distributes points by triangle area and then runs a

Poisson rejection pass so the result has an even minimum spacing instead of the

clumps you get from naive sampling. Hard edges can be walked separately so

silhouettes and creases stay sharp at low point counts. Material colors are

collected into a palette of up to 32 entries, so a multi material model keeps

its color identity in the cloud.

★ FULL SOURCE, NO BLACK BOXES ★

Three C# files, three shader files, one shared HLSL include. No DLLs, no third

party dependencies, no hidden runtime. Read it, edit it, ship it.

Perfect for holographic UI, ghosts and spirits, dancing characters, dissolve and respawn effects, sci fi scanners, data visualization, logo intros, landing pages and portfolio scenes.
