Poseidon CSG: Easily create levels by simply taking existing geometry you've made and intersecting meshes together. When two meshes with our script are intersected together, the end result is a clean, dynamic, union of the two.

Need a tunnel added to your room? Slide it in. Need to connect two spaces together? Slide them together. Using Poseidon is extremely intuitive and can greatly speed up your level creation! No more having to go back to a 3D modeler to punch holes in your environments - Poseidon handles all of that dynamically!

Features

  • Carve meshes together just by intersecting them with each other
  • Author geometry in the 3D modeler you already use, and import carvers automatically with a simple naming convention
  • Easily merge interior-facing meshes together by simply intersecting them with each other
  • Create proper geometry in your 3D Modeler of choice - no more having to mess with in-editor alternatives
  • Fully non-destructive workflow - everything is dynamic and can be undone, your source meshes are never modified, and you can remove Poseidon entirely when you're done with it
  • No lock-in: Doesn't force you to use it for everything, unlike other tools
  • Editor-time runner that recarves automatically as you move, rotate, scale, or re-import
  • Frame-budgeted async carving, so big carves never freeze the editor
  • Runtime carving for procedurally generated levels
  • World-space and object-space UV projection to kill texture seams where meshes meet
  • Layers and Carving Groups for nesting and isolating carves
  • Source-available — ships as plain C#, no DLLs, so you can read it, debug it, and extend it

Poseidon is useful if you want to be able to connect 3D spaces to each other dynamically, allowing you to create the meshes you want, and not have to anticipate every possible way they could ever be used by a level designer. Poseidon allows a level designer to make subtle tweaks to levels without having to send a mesh back to an artist. Poseidon allows you to create modular levels with very few pieces but without everything feeling repetitive and allows you to create unique geometry!

Technical details

Unity & pipelines

  • Unity 2022.3 LTS or newer (officially supported and tested).
  • Built-in, URP and HDRP — Poseidon edits meshes and doesn't touch your materials or shaders

What's included

  • Full C# source in two assembly definitions (runtime + editor). No DLLs
  • Example scenes covering intersection, layered mode, UVs, and runtime carving
  • XML documentation, so everything shows up in your IDE

Editor

  • Automatic recarving on transform, mesh and setting changes
  • Scene view overlay, Deferred Mode, and per-project preferences
  • Optional Mesh Cleanup post-pass to reduce triangle counts
  • Auto-importer: name a locator _POSEIDON in your modeler and it imports as a carver

Runtime

  • Entirely opt-in — nothing installs or ticks unless you enable it
  • Frame-budgeted carve operations with progress reporting
  • PoseidonRuntimeService for automatic change detection, or manual PoseidonOperation control
  • Callbacks and hooks for feeding NavMesh, custom colliders, or exporters

Requirements & limitations

  • Meshes must have Read/Write Enabled (the inspector warns you and offers a one-click fix)
  • Carvers work best as closed meshes; open bottoms can produce unexpected results
  • Carving runs frame-divided on Unity's main thread — Job System support is on the roadmap

Compatibility

Render pipelines supported in each Unity version

Works great on Standard Unity Pipeline, URP, and HDRP! Poseidon changes underlying meshes, which shouldn't matter for Pipelines. Example scenes and materials were made using Built-In/Standard Render pipeline and can be auto-upgraded.
