How to use the 3D High-Poly Models agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The 3D High-Poly Models skill is a set of written guidelines that tells an AI agent how to build highly detailed 3D geometry for close-up viewing and then turn it into lighter runtime assets that load and draw efficiently. It is aimed at developers building 3D web scenes and artists or technical designers preparing architectural or scanned-stone assets. After this guide you will know what the skill changes about the agent's behaviour, how to install it, how to phrase requests so it triggers, and what to check in the results.
3D High-Poly ModelsMengTo/Skills · MIT Download the skill Quick start
- 1Download the ZIP. Download the 3d-high-poly-models skill as a ZIP file from this page.
- 2Unzip into a skills folder. Extract it into ~/.claude/skills/ for personal use or into your project's .claude/skills/ folder.
- 3Or upload it in the Claude apps. In the Claude apps, open Settings, go to Capabilities, and upload the skill under Skills.
- 4Make a natural request. Describe the close-up detail, the target use such as a web viewer, and any load-time concern.
- 5Provide the inputs. Share reference images, scale, hero camera angle, and the current mesh or triangle count if available.
- 6Review the runtime output. Check the master versus runtime mesh at the closest camera distance and walk across LOD thresholds for holes or jumps.
- 7Measure performance. Record startup time, frame time, and draw calls and triangles on desktop and mobile before claiming a result.
What is an agent skill, and what does this one do?
An agent skill is a folder containing instructions that an AI agent can read and follow when a task matches the skill's description. This skill's description covers creating or integrating highly detailed 3D models with smooth silhouettes, shaped surfaces, believable bevels, and close-up geometry, then preparing suitable runtime LODs and loading.
When the skill is active, the agent checks the camera's viewpoints and where detail will actually be visible. It adds geometry to silhouettes and surface forms, uses material maps for microdetail, and keeps a detailed master model. It then produces lighter runtime versions using LODs (lower-detail copies for distant objects), instancing, and sensible shadow and loading strategies, followed by measured performance checks.
The skill is guidance text only. It does not include modelling software, and it does not run modelling tools for you.
Install the skill from the ZIP download
Download the skill as a ZIP file from the page where you found this guide. Unzip it so the skill folder ends up in one of two places: ~/.claude/skills/ to make it available across your projects, or a project's .claude/skills/ folder to limit it to that project.
If you use the Claude apps instead, open Settings, go to Capabilities, and upload the skill under Skills. The skill's files are SKILL.md, REFERENCES.md, and agents/openai.yaml.
- Personal install: ~/.claude/skills/
- Project install: .claude/skills/ inside your project
- Claude apps: Settings → Capabilities → Skills
How do you trigger the skill with natural requests?
You do not need a special command. The skill's description lists the situations it applies to: a user requests high polygon counts, ultra-realistic models, detailed architectural assets, or removal of visibly faceted geometry. Asking in those terms is the most reliable way to activate it.
State the target use as well as the look. Mentioning a web viewer, a real-time scene, or a load-time concern gives the agent the context it needs to prepare runtime versions.
- Make the stone wall in this scene look realistic up close, and prepare LODs so the web viewer still loads quickly.
- Remove the faceting from the rounded roof edges on this building model and check the silhouette at the hero camera angle.
- I need ultra-realistic scanned rock assets for an interactive walkthrough. Keep a master model and export a GLB for the runtime.
What should you provide for good results?
The skill asks the agent to inspect several things before building anything: the reference, the intended hero angle, the closest camera approach, the orbit range, the model's scale, the current mesh, and the target hardware. Giving the agent these details up front, or the files that contain them, makes the output more useful.
The skill also requires a 3D modelling tool or asset pipeline, which the files do not specify. For runtime checks it refers to Three.js or another real-time viewer. Without those, the agent can still write guidance and plans, but it cannot run the modelling or viewer checks itself.
- A 3D modelling tool or asset pipeline available to you
- Three.js or another real-time viewer for LOD and loading checks
- Reference images, real dimensions, and the current triangle count if you have it
What does the skill ask the agent to check?
The skill asks the agent to judge realism by silhouette, proportions, material response, and lighting, not by polygon count alone. It recommends recording the current triangle count and draw calls rather than calling an asset high-poly from appearance. It also asks for the runtime to be checked at the closest camera distance and across LOD thresholds, with startup, first interaction, and frame time measured on desktop and mobile.
The skill notes that compression reduces transfer size but does not inherently reduce runtime triangle count, and that instancing, LOD, and geometry compression each solve different costs. Report unique asset triangles separately from the triangles drawn across instances and passes.
Safety notes: scripts and network access
The skill runs no scripts and uses no network access, according to its own assessment. It consists of instruction text and reference links. The REFERENCES.md file lists sources such as the Three.js LOD, GLTFLoader, and InstancedMesh documentation and two Seijaku code links.
Because the skill contains no scripts, any code the agent writes or runs comes from the agent and your tools, so review it as you would any generated code before running it on your project.
Who should skip this skill?
The skill adds process that is not worth it for simple low-poly or stylised projects. It is also not the right choice if you expect it to drive modelling software automatically, because it contains only instructions and no tool integrations.
What people use it for
- Preparing a detailed scanned-stone asset for an interactive web walkthrough, with a master model and a lighter runtime version.
- Removing visible faceting from rounded architectural forms such as roof edges while checking the silhouette at the hero camera angle.
- Planning LOD levels and instancing for repeated roof tiles or foliage in a large real-time site.
- Auditing an existing model's triangle count and draw calls before deciding what detail to add or remove.
Frequently asked questions
How do I install the 3D High-Poly Models agent skill?
Download the skill ZIP from this page and unzip it into ~/.claude/skills/ for personal use or a project's .claude/skills/ folder. In the Claude apps, you can instead upload it under Settings, then Capabilities, then Skills.
Is the 3D High-Poly Models skill free?
The skill is released under the MIT licence, as listed on this page. The licence terms are the authoritative source for what you may do with it.
What do I need to use this skill?
You need a 3D modelling tool or asset pipeline, which the skill does not specify, and Three.js or another real-time viewer for the LOD and loading checks. The skill runs no scripts and uses no network access.
Does this skill create 3D models by itself?
No. The skill is guidance text and does not include modelling software or tool integrations. The agent follows its instructions, but you still need your own modelling tools to build and export the assets.
Will the skill make my scene faster?
It asks the agent to prepare LODs, instancing, shadow budgets, and staged loading, and to measure the results. Speed gains depend on your scene and must be confirmed by profiling, because the skill states there is no universal triangle budget.
When should I not use this skill?
Skip it for simple low-poly or stylised projects, where the extra process adds overhead without benefit. Also skip it if you expect automatic modelling tool control.

Our verdict
Use this skill if you build detailed 3D assets for web or real-time viewers and need a disciplined process for keeping close-up quality while controlling load time and draw cost. Skip it for simple or stylised projects, or if you need an agent that operates modelling software directly, since it provides guidance only.
