Apparance Procedural Generation System

Promotional VideoWebsiteSupport Forums

⭐Demo version available for $34 on…

Apparance is a procedural generation plug-in designed to allow the interactive visual authoring of detailed and expansive 3D worlds. A play-space for procedural logic and their use in the generation of environments and objects. A fusion of programming and modelling that gives extensive control over your applications procedural elements.

Watch the Promotional Video for a full rundown of the capabilities of Apparance.

The Apparance project is inspired by the flexibility of non-linear and node-based editing systems used in film, television, and games. The amazing compression achieved by the demo-scene using mathematics and procedural generation points towards the vast possibilities of large scale procedurally built game worlds.

  • Experiment with procedural generation of meshes* too.

Add Variety, Save Time

  • Increase variety in your game with unique generated assets
  • Save time and resources populating the spaces in your world
  • Build re-usable and modular objects

Fully Interactive Editing

  • Enjoy fully interactive editing of parameters, graph structure, and all internal values.
  • Scrub through the parameter space to find the results you are after.
  • Rapidly test thousands of combinations as you work.

Rapid Iteration

  • Rapidly iterate on your designs, play with graph configuration, explore your parameter space.
  • Drag-and-drop connections and procedures to experiment.

High Speed Run-time Generation

  • Fully run-time multi-threaded background generation
  • Mesh* accumulation and instanced rendering support
  • Allows for endless unique creations and experiences

Node Based Editor

  • Use node based scripting to author* your procedural logic.
  • Create powerful hierarchies of procedures yet manage graph complexity by building up a library of re-usable parts.
  • It’s procedures all the way down until you reach a fundamental operator that does the work.

Comprehensive Documentation

  • Detailed documentation available online for plugin and editor
  • Directory of fundamental procedural operators
  • Support forums for questions, reporting, and discussion


  • Mesh generation is currently an experimental feature, to be expanded in future release.
  • Procedures are authored live within a separate standalone editor application that the plugin downloads automatically on first use.
  • This is the professional commercial version of Apparance for use in paid-for products and fully funded projects. To try out the plugin or use in other scenarios (e.g. education, game-jams, evaluation, or non-profit projects) you can purchase the non-commercial demo version for a reduced fee, see the Apparance Products Page for details.
