CosmoNode is a node-based procedural geometry tool for Unity that enables visual mesh generation, parametric modeling, and runtime mesh workflows without code.CosmoNode is a powerful node-based procedural geometry system for Unity that enables developers to create, modify, and process meshes using an intuitive visual graph workflow. Inspired by the procedural approaches used in Blender Geometry Nodes and Houdini, CosmoNode brings a flexible, non-destructive geometry pipeline directly into Unity.Procedural Geometry with Visual NodesWith CosmoNode, complex mesh operations can be built visually using nodes instead of code. Geometry can be generated, transformed, combined, and processed through a modular graph, allowing you to build parametric systems that remain easy to edit and extend.This workflow allows you to:Generate procedural meshes directly inside UnityBuild reusable parametric assetsModify geometry through a visual node graphQuickly iterate by adjusting parameters in real timeCreate non-destructive modeling pipelinesBecause graphs are modular, complex systems can be built by combining small reusable operations, making projects easier to maintain and expand.Built for Runtime GeometryA core focus of CosmoNode is full runtime support.The same graphs used during development can run directly in-game, enabling dynamic geometry creation and modification while your application is running.This makes CosmoNode ideal for:Procedural environmentsRuntime level generationDynamic mesh effectsPlayer-driven geometry changesInteractive tools and simulationsGraph parameters can be controlled from scripts or gameplay systems, allowing geometry to react dynamically to player input, gameplay events, or simulation data.Flexible Geometry ProcessingCosmoNode includes a wide range of geometry operations that can be combined into powerful procedural systems.Supported workflows include:Mesh generation and transformationGeometry manipulation and processingParametric modelingBoolean operations between meshesAttribute and data-driven workflowsProcedural mesh pipelinesThese tools allow you to construct everything from simple procedural shapes to advanced geometry systems.Inspired by Blender and HoudiniCosmoNode combines ideas from modern procedural tools like Blender and Houdini, bringing a powerful procedural workflow directly into Unity.Like Blender’s Geometry Nodes, CosmoNode provides an intuitive node-based workflow for building and editing geometry visually.Similar to Houdini’s Unity Engine integration, CosmoNode is designed to operate directly inside Unity, enabling procedural systems to be used within your project pipeline.Unlike traditional integrations, CosmoNode also supports fully dynamic runtime execution, allowing procedural graphs to generate and modify geometry while the game is running.The result is a flexible workflow that combines artist-friendly visual tools with powerful runtime procedural systems, enabling both artists and programmers to create complex geometry pipelines directly inside Unity.Why CosmoNode Instead of Blender or Houdini?Tools like Blender and Houdini are powerful procedural modeling environments, but they are primarily designed for external asset creation pipelines. Geometry is usually generated in those tools and then exported into Unity as static meshes.CosmoNode takes a different approach by bringing the procedural workflow directly inside Unity.Native Unity WorkflowCosmoNode runs entirely within Unity, allowing you to create and edit procedural geometry without switching between multiple applications or managing export pipelines.Full Runtime SupportUnlike most external procedural tools, CosmoNode graphs can run directly at runtime. Geometry can be generated, modified, or rebuilt dynamically while your application is running.This enables systems such as:Procedural worlds generated during gameplayDynamic environment changesPlayer-driven geometry modificationRuntime procedural tools and simulationsBy combining a Blender-like node workflow, Houdini-style procedural flexibility, and native Unity runtime execution, CosmoNode allows developers to build procedural systems that are fully integrated with their game logic and runtime environments.Use CasesCosmoNode enables a wide range of procedural workflows directly inside Unity. Its runtime-capable node system makes it suitable for both development-time tools and fully dynamic in-game systems.Common use cases include:Procedural environment generationGenerate terrain features, structures, props, and environmental geometry through reusable procedural graphs.Runtime world generationCreate dynamic worlds that are generated or modified while the game is running.Parametric assetsBuild customizable assets whose shape and structure can be adjusted through parameters.Procedural modeling toolsCreate automated modeling workflows that generate complex geometry from simple inputs.Interactive geometry systemsAllow players or gameplay systems to modify meshes dynamically during gameplay.Mesh processing pipelinesBuild reusable systems that manipulate meshes through operations such as transformations, booleans, and attribute processing.Example WorkflowsUsing CosmoNode, developers can build procedural systems such as:Procedural buildings with adjustable floors, windows, and layoutsDynamic road or path generation systemsRuntime destructible or modifiable geometryParametric props and environment assetsProcedural level generation toolsMesh processing pipelines for custom modeling workflowsBecause CosmoNode graphs support runtime execution, these systems can be used both during development and directly inside the running game.Key technical features:Fully node-based procedural geometry systemRuntime execution support for dynamic mesh generation in-gameVisual graph editor for building geometry pipelinesParametric modeling workflowsProcedural mesh generation and processingMesh boolean operationsModular node architecture for flexible procedural systemsRuntime parameter control through scriptsCompatible with standard Unity meshes and componentsPlatform NotesCosmoNode supports Windows, macOS, and Linux through Unity.Some nodes rely on platform-specific functionality and may not currently work on macOS or Linux.These limitations typically affect a small subset of nodes, while the majority of the system functions normally across platforms.DocumentationFull documentation, guides, and examples are available online:Documentation:https://uumutunal.github.io/CosmoNode_Manual/The documentation includes:Getting started guidesNode reference and explanationsRuntime API usageThis makes it easy to quickly learn the system and integrate CosmoNode into your Unity projects.I have used LLMs occasionally to help generate small code snippets during development. All code was reviewed, modified, and integrated manually by the me.
