VFX Mesh Generator - Professional Model Generation Tool for VFX Artists

VFXMeshGenerator is a procedural mesh generation plugin for the Unity Editor, designed specifically for VFX production workflows. It allows you to create, tweak, and export 3D meshes in real time through a parametric panel — no external 3D modeling software required to quickly produce the fundamental geometries used in visual effects.
Key Features
7 VFX-Oriented Mesh Generators
Cone — Light beams, shockwave cones, focus markers. Supports truncated cones and open ends.
Ring — Halos, shields, portals, energy rings. Supports partial arcs, bulge, taper, and ring twist.
Spiral — Tornadoes, vortices, energy spirals. Adjustable turns, ribbon width, and end taper.
Ribbon — Trailing ribbons, silk strips, slash trails. Supports curvature, narrow ends, and ring rotation.
Sphere — Explosion spheres, shields. Supports icosphere mode (uniform vertex distribution) and hemisphere.
Plane — VFX billboards, decal planes. Supports polar coordinate mode.
Revolution — Vases, columns, horns, and any axis-symmetric shape. Profile controlled via AnimationCurve.
Each generator provides detailed subdivision parameters (segments, rings, arc, taper, bulge, etc.) for precise control from simple geometry to complex forms.
3 Stackable Modifiers
Noise Displacement — Perturbs vertices along normals using fractal Brownian motion for organic deformation. Adjustable strength, frequency, octaves, and seed.
Twist — Progressively rotates vertices along the primary axis for torsion effects.
Taper — Linearly scales the cross-section from one end to the other for tapered or flared shapes.
Modifiers can be freely combined and stacked to produce dramatically different forms from the same base mesh.
UV & Vertex Color System
3 UV mapping modes: Standard, Polar, Spherical
UV transforms: 90° step rotation, Flip U/V
4 vertex color modes: None, Gradient (custom Gradient with direction selection), Radial falloff, Height mapping
Vertex colors can directly drive particle systems, shader animations, or VAT masks and blending.
Real-Time Preview & Interaction
Isolated scene rendering with orbital camera (free rotate/zoom)
Wireframe overlay, reference grid, vertex color gradient visualization
Instant refresh on parameter changes — what you see is what you get
Flexible Export Options
Export as Unity .asset (ready to use) or .obj (universal format)
Optional Lightmap UV generation (with hard angle, pack margin, and other parameters)
Read/Write toggle, automatic normal/tangent generation
Full Undo/Redo support
Design Philosophy
Pure Editor tool — zero runtime overhead, no dependencies introduced
Artist-friendly parametric design — all controls have clear labels and range constraints, ready to use out of the box
Modular architecture (IMeshGenerator + IMeshModifier interfaces) — easy to extend with custom generators and modifiers
Built on URP render pipeline, settings persisted via ScriptableObject
Ideal For
VAT (Vertex Animation Texture) projects — quickly generate meshes with proper UVs and vertex colors for VAT animation
Particle effects & skill effects — produce common VFX geometries like light beams, shockwaves, shields, and vortices
Mobile games — parametrically generate low-poly meshes without involving modelers for simple geometry
