Visual Effect Graph

Qu'il s'agisse d'un hologramme de science-fiction, d'un dragon crachant du feu ou d'une fenêtre frappée par la pluie, les effets nodaux et les fonctionnalités adaptatives de Visual Effect Graph vous permettront de créer de magnifiques effets spéciaux en temps réel.

Real-time VFX

This visual node-based solution enables you to design visual effects, from simple common particle behaviors to complex simulations running on the GPU.

Available for PC, consoles, XR and high-end mobile, VFX Graph has been used in games such as V Rising, Road 96, Hardspace: Shipbreaker, and Syberia: The World Before

Create procedural effects without code

Inspired by leading film tools, VFX Graph combines blocks, nodes, and sequencers to help you author more powerful visual effects.

VFX Graph Shader

Visual authoring

VFX Graph uses a mix of flow- (vertical) and node- (horizontal) based authoring. Flow authoring assembles building blocks for spawning, initialization, update, and rendering stages on which a combination of nodes can be plugged to create advanced procedural effects. Node Search, Sticky Notes, and Subgraphs allow you to build and organize your effects efficiently. With the Blackboard VFX Graphs utility panel, you can expose properties so other users like artists or game designers can customize effects to their needs.

Author particle shaders using Unity’s node-based tool Shader Graph, and sequence multiple effects together or events within an effect using VFX Graph integration with Timeline.

Simulate millions of particles

Leverage GPU power to emit and simulate millions of particles in real-time. 

Emit particles from points (for example fireworks), shapes (dust in a room), 2D or 3D textures, surfaces like static and skinned meshes, or signed distance fields (a character turning into sand), point caches, camera buffers (a dissolving world), or structured buffers to sample custom data like statistics or your own simulation.

Each spawner can control time, loop, and delay to spawn particles a set number of times with predetermined intervals and durations, and be updated using various forces or turbulence systems to generate lifelike systems.


Advanced rendering

VFX Graph works with the Universal Render Pipeline (URP), URP’s 2D Renderer, and the High Definition Render Pipeline (HDRP). 

You can render hundreds of thousands of particles of many types in real-time: Use Points to create snow or dust; procedural primitives like quads, triangles, or octagons for small particles like leaves; flipbooks for animated particles like smoke; meshes to render more complex objects like debris; lines to create sparks; or strips to create vehicle trails or tentacles. You can even modify the world using distortion in HDRP to simulate heat or spawn Decals to render impacts, burnt spots, or painting stains.

Powerful particle shaders

VFX Graph offers premade materials with a comprehensive set of ready-to-use parameters to shade the most common particles. 

For more advanced effects, you can visually author your own pixel and fragment shaders with Shader Graph and use them in VFX Graph. This approach allows you to create custom looks, use advanced lighting models like HDRP’s hair and fabric shaders, as well as animate vertices to deform or animate particles on the GPU for effects like bubbles or flocks of birds.

Dynamic and interactive particles

Build particles that can interact with the world in multiple creative ways. Sparks or debris could collide with or be attracted to surrounding objects using custom physics primitives using the Camera’s Depth Buffer on an entire world, or Signed Distance Fields for more complex objects. 

Use Events to trigger systems, for example producing smoke when a meteorite hits the ground. Output Events can be sent to trigger systems outside of the VFX Graph, like cuing a camera shake upon impact.

For even richer effects, one can sample advanced data from a custom simulation or numbers from a database using graphics buffers.

Optimized performance

Running both simulation and rendering on the GPU in a single program, VFX Graph can execute complex and rich particles without back and forth with the CPU.

An advanced and configurable bounding volume system and culling options allow you to not render effects which are not visible.

To save performance when rendering many complex objects, mesh LODs enable the use of simple representations when a detailed object is not needed, and leveraging HDRP’s low-resolution transparents option can limit costly overdraws.

Finally, you can run hundreds of instances of the same effect efficiently using the new instancing system.

Road 96 de DigixArt

A powerful toolchain

VFX are often composed of source data coming from different software. To help generate some of this data, plug-ins for Houdini are provided to export point caches, vector fields, signed distance fields, and Vertex Animation Textures (VAT)

Unity’s Texture 3D importer allows you to import and preview Volumetrics, Slices, and Signed Distance Fields directly usable in VFX Graph.

To reduce iteration times and mistakes when changing a source asset, you can directly bake Point Caches in Editor, bake Signed Distance Fields in Editor or at runtime, or iterate on Flipbook textures in the Editor, without needing to reopen another software.
