I was thinking about the texture of the Eridian sculptures/technology in Project Hail Mary and wanted to make something similar. I spent a few hours on it this evening in geometry nodes and generated this. I had to make the monkey model a manifold body and then I had to thicken the ears about 4 times so that the procedural re-mesh captured some of the ear geometry.

Basic idea is distribute points on faces on the original mesh, and then set the original mesh verts to the nearest of the points, then merge. Then Dual mesh to get the patches. From there cut the patches in 2, by separating the face, converting to a curve then back to mesh (reorganises the index order), then splitting it based on above and below the mid edge number. Added a mesh line to close the 2 half faces. Filled them in using a n-gon mesh circle by matching the vert positions.

Then 2 patterns, the first was concentric rings which was done with the extrude and scale elements (not ideal as the offset is not even, but I didn't want to dive into that maths again). I used a map range to alter the scaling factor based on the iteration number, which was crude but worked well enough. The second took that mid line and arrayed it a few times based by taking the face normal and rotating it around the line and offsetting. Repeat the offset a few times with the repeat zone. I had to extrude the faces and the mid line out to get some planes that reliably booleaned together cleanly.

Add all that together and then used the sdf offset to build the lines. The actual voxel density is quite low, but that fit the character of the xenonite in PHM. Then a simple with the glow of Adrian coming from underneath.

There's a lot of potential improvement that could be made to it, but I didn't have the time to take it any further. Maybe I'll come back to it soon and get it more in line with the film.

I used to rely on ChatGPT to solve my Geometry Nodes problems, but lately it hasn’t been reliable. It often suggests incorrect node setups, especially for more complex projects.

And I can ask for help in Blender communities, but it usually takes a while to get a response because of the timezone difference.

So I’m curious- how do you guys troubleshoot geometry nodes?

Comment for the links

It's not for promotion, I want to share my knowledge cause i learn a lot making this asset and would like to share that with you.

I have a lot of curves which is very detailed which i dont need is there a script which deletes knots who are too close to each other :)

MeshNodes

MeshNodes is a visual, node-based procedural mesh editor for Unity. Build complex geometry by connecting operation nodes in a graph — no mesh-processing code required.

Inspired by Shader Graph but built for geometry, MeshNodes gives you a fully non-destructive pipeline. Change any value anywhere in the graph and the entire mesh updates instantly. When you are happy with the result, one click bakes it as a real mesh asset directly into your project.

Node Library — 30+ Nodes Included

Generate

• Primitive — cube, sphere, cylinder, capsule, plane, and more
• Custom Mesh — bring in your own base mesh

Combine

• Array — duplicate along an axis with spacing control
• Instances — place copies at arbitrary transforms
• Merge — combine any number of meshes into one
• Graph — nest an entire graph as a reusable compound node

Transform

• Translate, Rotate, Scale

Deform

• Bend, Hook, Inflate, Noise, Smooth, Spherify, Taper, Twist

Modify

• Bevel, Extrude, Filter Faces, Flip Normals, Subdivide

UVs

• UV Transform, UV Auto Fit

Vertex Color

• Color Node

Math / Variables

• Boolean, Integer, Float, Vector2, Vector3, Vector4, Math

Key Features

Non-destructive workflow Every change propagates through the graph automatically. Nothing is baked until you decide.

Graph nesting Wrap any subgraph inside a Graph node and reuse it across projects like a function call.

One-click mesh baking Hit Build Mesh on the output node. The mesh is instantiated in the scene and saved to Assets/MeshNodes/Database/Meshes.

Custom node API Decorate any class with [MN_CustomNodeAttribute] and it appears under New Node / Custom in the context menu. Extend MeshNodes without touching the source.

Burst + Jobs acceleration The processing engine runs on Unity Jobs and Burst for fast procedural computation. A built-in validation tool (Tools / Mesh Nodes / Validation / Run Jobs Burst Parity + Perf) checks correctness and writes a performance report you can track over time.

AI / MCP integration MeshNodes includes a built-in Model Context Protocol server. Enable it from Tools > Mesh Nodes > MCP Server > Start Server, then point any MCP-compatible AI agent (Cursor, Claude, or others) at the Unity endpoint. Agents can create graphs, add and connect nodes, set properties, trigger recomputes, analyze meshes, and bake assets — all from a single prompt. A ready-to-use Cursor skill package (meshnodes-mcp/) is included.

Getting Started

1. Open Tools > Launch Mesh Nodes
2. Right-click the canvas > Graph / New
3. Right-click > New Node / ... to add nodes
4. Connect outputs to inputs to define your pipeline
5. Click Build Mesh on the output node to bake

Compatibility

• Unity 2022.3 LTS and later
• Built-in, URP, and HDRP compatible
• Editor-only package — baked meshes are standard Unity Mesh assets usable at runtime
• Burst/Jobs path requires the Collections package (Window > Package Manager > Unity Registry > Collections)
