# Playable 3D Previz for Seedance Reference Video in ComfyUI — prompt skill for camera & shots

> **For AI agents:** find the right skill in one call — `curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>"` returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add `.md` to its path. Before generating anything, show the person the options on the how-to page. From a terminal: `curl -fsSL https://varg.ai/install | sh` installs the vargai CLI (https://varg.ai/how-to/cli.md): `vargai search` and `vargai install <slug>` with no key, every varg model after `vargai login`.

ComfyUI nodes: build a 3D blockout set, act it with WASD, cut live cameras and export a 720p reference clip for Seedance or MiniMax H3.

## What it does

Three ComfyUI nodes turn video generation into playable previz: Staging builds navigable 3D blockout sets from presets (courthouse square, gas station, beach, warehouse) or from an AI prompt via the included stage-builder SKILL.md, Acting records humanoid and vehicle actors with WASD controls and ghost replays, and Directing cuts live cameras with an anti-collision spring arm. The output is a 720p VIDEO reference for models such as Seedance 2.5 / 2.0 Fast or MiniMax H3 reference-to-video. Install through ComfyUI Manager, comfy-cli or git clone; MIT.

## Use when

- Act out character and vehicle movement instead of prompting it
- Cut between cameras live and export a reference video
- Drive Seedance 2.5 or MiniMax H3 reference-to-video from a blockout
- Build a 3D set from presets or an AI prompt

## Install

- comfyui: `comfy node install comfyui-scene-camera-action`
- Any agent, with the vargai CLI: `vargai install comfyui-scene-camera-action`

- Any agent with a terminal: `curl -fsSL https://varg.ai/install | sh` (Windows: `irm https://varg.ai/install.ps1 | iex`), then `vargai login` and every model is a command — `vargai generate_video …`, `vargai estimate_cost …` (https://varg.ai/how-to/cli/)
- Claude Code: `claude plugin marketplace add vargHQ/skills && claude plugin install varg@varg` (skill + hosted MCP)
