What it does

Make It 3D is an agent skill from VectorSpaceLab/AREX-Skill. Use this repo skill for Make-It-3D single-image 3D creation, including CUDA asset setup, alpha-image validation, coarse NeRF optimization, refinement, rendering, export, and troubleshooting.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts and reference files (for example `references/backend-and-assets.md`, `references/quickstart.md` and `references/repo-provenance.md`).

It sits in AI & LLM Engineering. It works with CUDA. The repository describes itself as: A Skill Library for Automated Machine Learning. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit ac3fe1a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com
    • download.pytorch.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Make It 3D loads about 1.4k tokens when it runs, and up to ~4.9k if it reads all its reference files. Until then it costs about 50 tokens; SKILL.md has 519 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Make-It-3D Repo Skill

Use this skill when a task is about operating Make-It-3D, the ICCV 2023 single-image-to-3D system that optimizes a NeRF with DPT depth, CLIP/Stable-Diffusion guidance, and a refinement/export stage. The skill is self-contained: use the bundled references and scripts here rather than reopening the source README, demos, or scripts just to recover commands, flags, dependencies, or failure handling.

Before giving run commands, check freshness in references/repo-provenance.md. The source snapshot is a script-style research repo, not a pip-installable root package. Future use normally starts from a Make-It-3D checkout plus a CUDA-capable Python environment.

Minimal Operating Sequence

  1. Confirm a compatible environment before long runs. Use scripts/make_it_3d_env_check.py against the user's working checkout and asset locations. Make-It-3D expects CUDA for the practical pipeline; the source forces opt.cuda_ray = True, so raymarching CUDA support matters even when a user asks for --backbone vanilla.
  2. Validate the reference image. The main script reads --ref_path with cv2.IMREAD_UNCHANGED and immediately converts BGRA to RGBA, so the reference should be a four-channel image with a usable foreground alpha mask. Use sub-skills/environment-and-inputs/scripts/validate_alpha_input.py.
  3. Avoid unnecessary BLIP2 downloads when possible. If the user already knows the object prompt, pass --text "..."; otherwise main.py loads BLIP2 (Salesforce/blip2-opt-2.7b) for captioning, which requires network/model cache and substantial GPU memory.
  4. Run coarse optimization in two phases. Use sub-skills/coarse-training/scripts/build_training_commands.py to emit the README-backed frontal phase and full-360 phase with correct flags.
  5. Run refinement/export only after a usable coarse workspace exists. Use sub-skills/refinement-and-export/scripts/build_refine_export_commands.py. Note that in the inspected source the refine block is nested under the --final path; include --final --refine if --refine alone does not execute refinement.

Public Install Skeleton

Use the exact versions required by the user's machine when possible, but the source documentation used this public install pattern:

bash
pip install torch==1.10.0+cu113 torchvision==0.11.1+cu113 torchaudio==0.10.0+cu113 -f https://download.pytorch.org/whl/cu113/torch_stable.html
pip install git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torch
pip install git+https://github.com/openai/CLIP.git
pip install git+https://github.com/huggingface/diffusers.git git+https://github.com/huggingface/huggingface_hub.git
pip install git+https://github.com/facebookresearch/pytorch3d.git
pip install git+https://github.com/S-aiueo32/contextual_loss_pytorch.git
pip install -r requirements.txt
pip install ./raymarching

Read references/backend-and-assets.md before executing this literally: the repository pins older CUDA/PyTorch-era dependencies, while modern hosts often require adjusted torch/PyTorch3D/tiny-cuda-nn builds.

Do Not Do This

  • Do not start training before checking CUDA, raymarching build/toolkit readiness, DPT weights, Hugging Face access/cache, and alpha input validity.
  • Do not promise CPU reproduction of the main Make-It-3D pipeline. CPU checks can validate scripts and some source facts, but they do not substitute for CUDA training/rendering behavior.
  • Do not tell future users to read the original README or source files for basic commands. The equivalent distilled guidance is in this skill tree.
  • Do not expose local environment names, absolute checkout paths, or private tokens in user-facing outputs. Ask users to provide their own paths and credentials at runtime.
