Generate a single static 3D prop — sword, barrel, chest, lantern, throne, statue — one isolated object, no rigging, wired as a MeshInstance3D.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Prop Model — Generate One Static 3D Prop and Wire It One prop, one mesh, one MeshInstance3D. Most game-world objects are static props, so this is the most common 3D-asset call. The skill keeps two things tight: the **prompt shape** that produces a clean isolated mesh on the first try, and the **wire-in pattern** that gets the asset into the scene without leaving orphans in `res://assets/models/`. The backing tool is `summer_generate_3d`. Default model is `hunyuan` (Hunyuan 3D v3.1 Pro — best quality). Use `trellis` when speed matters (Trellis 2 is ~2× faster, slightly lower fidelity). `meshy` is the legacy fallback — only pick it if the user asks by name. ## When to use - "Make me a treasure chest." - "Generate a viking axe." - "I need a wooden barrel for the cellar." - "Create a sci-fi crate." - Any single, static, non-character, non-modular object the player will see in 3D space. ## When NOT to use - Character / humanoid → `character-model` (needs T-pose + rig pass). - A set of matching pieces (walls, floors, doors, pillars) → `environment-kit` (style-locked family). - Trees, rocks, foliage → `organic-model` (organic forgives AI artifacts; cheaper recipe). …

How to install
mdr add summerengine/summer/prop-model@sha256:629577126d9a5397The line at the top of this page pins the label git:20261010.4ade947, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
