MeshNodes

Visual procedural mesh editor for Unity. Connect nodes. Bake meshes. No mesh-processing code.

Inspired by Shader Graph — built for geometry. Non-destructive graphs. Live preview. One-click bake into a real Unity mesh asset.

Current version: 2.1.1

Why MeshNodes?

Stop writing repetitive mesh code. Build a pipeline of nodes instead — generate, deform, UV, color, combine — and change any value upstream to update the whole mesh instantly.

When you're done, hit Build Mesh. The result lands in your scene and saves under Assets/MeshNodes/Database/Meshes.

What's new in 2.1.1

If you last downloaded the 2024 package, this is a major upgrade — not a patch.

• Job System + Burst — every mesh node runs on the C# Job System, with Burst where it counts
• MCP / AI — built-in Model Context Protocol server so Cursor, Claude, and other agents can create graphs, wire nodes, set properties, recompute, and bake from plain language
• Auto-Resume MCP — server comes back after C# compile / assembly reload; AI sessions survive domain reload
• Batch recipes — agents can build a full multi-node graph from one JSON recipe (mn_build_graph_from_recipe / mn_get_asset_recipe)
• Editor QoL — zoom to 0.15x, cleaner layout/panning, passable variables, tooltips, node grouping, better library search
• Stability — safer normals on empty meshes; fewer editor memory leaks

A Cursor skill package (meshnodes-mcp/) is included.

Key features

• Non-destructive graph workflow
• Graph nesting (compound / subgraph nodes)
• One-click mesh baking
• Custom nodes via [MN_CustomNodeAttribute]
• Burst + Jobs acceleration + parity validation tool
• AI-drivable via built-in MCP server

---

Getting started

1. Tools → Launch Mesh Nodes
2. Right-click → Graph / New
3. Right-click → New Node / ...
4. Connect outputs to inputs
5. Click Build Mesh on the output node

---

Compatibility

• Unity 2022.3 LTS and later
• Built-in / URP / HDRP
• Editor-only package — baked meshes are standard Unity Mesh assets
• Burst/Jobs path needs the Collections package

---

Upgrade note (v1 → v2)

v1.x graphs need a manual migrate:

1. Back up the project
2. Replace legacy nodes with v2 equivalents from New Node
3. Reconnect ports
4. Optional: Tools → Mesh Nodes → Validation → Run Jobs Burst Parity + Perf
5. Re-bake with Build Mesh
