Meshy-6

You've got an image of an object and you need a 3D model of it - for a render, a game asset, a print. Meshy-6 does that end to end: drop in one or more reference images, and the cloud returns a textured GLB mesh with polycount and texture settings you control. It's a paid, hosted 3D pipeline, and the whole thing saves straight to your ComfyUI output folder.

How it works

This is a 3dInference node, so unlike the image nodes it doesn't return a tensor - the pack downloads the generated model to your output folder and hands back a file_path string. The model runs on Runware's cloud (Meshy's generator), so there's no local mesh/UV/rendering stack to install. You get a .glb (the only outputFormat, so don't go looking for OBJ or FBX here).

The inputs that matter for a first run:

• images / referenceImages (IMAGE) - your source photos. For image-to-3D, feed one or more views.
• positivePrompt (STRING) - describes the object; needed for text-to-3D, and it steers the mesh when you have reference images too.
• numberResults (default 1, max 4) - how many variations to generate, each with a different seed.

The long settings list is Meshy's actual parameter surface, and it's mostly "set once and forget":

• settings.polyCount (default 30000, range 100–300k) - target triangle/quad count. Higher = smoother but bigger files.
• settings.meshType (standard/lowpoly) and settings.topology (triangle/quad) - mesh character. Lowpoly + quad is your game-asset combo.
• settings.texture (default true) - generate a texture or return bare mesh. Turn off for pure geometry.
• settings.pbr (default false) - adds metallic/roughness/normal maps (plus emission). You want this for renders, not for raw geometry.
• settings.hdTexture (default false) - 4K base color instead of 2K. PBR maps stay 2K regardless.
• settings.pose (none/a-pose/t-pose) and settings.symmetry (off/auto/on) - mostly for character/creature models.
• settings.removeLighting (default true) - bakes out highlights so the texture works under your own lights. Leave it on.
• settings.autoSize, settings.origin (bottom/center), settings.remesh, settings.decimation, settings.moderation - quality-of-life and safety toggles.

Install

It's part of ComfyUI-Runware:

cd ComfyUI/custom_nodes
git clone https://github.com/Runware/ComfyUI-Runware
pip install -r ComfyUI-Runware/requirements.txt

Restart (or ComfyUI Manager → search "Runware"). You'll need a Runware API key - Settings → Runware API key, RUNWARE_API_KEY, or runware auth login.

Gotchas

This is the most expensive category in the pack - 3D generation is a real GPU job, and the title bar's cost readout will show it. Don't batch numberResults up to 4 casually. Also: the output is a file path, so wire it into a file/preview node that reads paths, and check the output folder for the GLB. If the mesh comes back lumpier than expected, try settings.polyCount up and settings.remesh on rather than re-prompting.
