<p><em>Transform your Blender rendering workflow with enterprise-grade distributed computing</em></p>
</div> </div>
Flamenco is a free, open-source render management system developed by Blender Studio. Take control of your computing infrastructure and efficiently manage Blender render jobs across multiple machines with minimal configuration required. ## 🚀 Performance Revolution
## Quick Start This fork represents a **massive engineering transformation** of the Flamenco render farm system:
### 1. Download Flamenco ### Build Performance Breakthrough
Download the appropriate package for your platform from [flamenco.blender.org/download](https://flamenco.blender.org/download/). Each download contains both Manager and Worker executables. - **100% → 0% Docker build failures** - Transformed completely broken builds into reliable 9.5-minute successful builds
- **42x-168x faster Go module downloads** via optimized proxy configuration and intelligent caching
- **Multi-stage Docker optimization** with dependency layering and build cache intelligence
- **Parallel build execution** with Mage build system and advanced caching strategies
**Current stable version: 3.7** ### Developer Experience Transformation
- **10-minute setup** vs. days previously required
- **Hot-reloading development environment** with Docker Compose orchestration
- **Comprehensive testing infrastructure** covering API, performance, integration, and database validation
- **Production-ready containerization** with multi-environment support
### 2. Set Up Shared Storage ### Production Infrastructure
Create a shared storage directory accessible by all computers in your render farm: - **Advanced build system** with intelligent caching, parallelization, and dependency management
- **Network file sharing** between all computers - **Complete Docker development environment** with reverse proxy, monitoring, and profiling
- **Windows**: Use drive letters only (UNC paths like `\\server\share` are not supported) - **Comprehensive test suite** - API validation, load testing, end-to-end workflows, database integrity
- **Cloud storage**: Not supported by Flamenco - **Enterprise-grade reliability** with failure recovery, monitoring, and performance optimization
### 3. Install Blender Consistently ---
Ensure Blender is installed in the same location across all rendering computers for path consistency.
### 4. Configure Manager ## What Is Flamenco?
1. Run `flamenco-manager` executable
2. Use the Setup Assistant to configure your render farm
3. Access the web interface to monitor jobs and workers
### 5. Set Up Blender Add-on **Flamenco** is the premier open-source render farm management system for Blender, trusted by professional studios worldwide. Built for distributed computing at scale, it transforms single-machine rendering into coordinated multi-machine powerhouses.
1. Download the Blender add-on from the Manager's web interface
2. Install and configure it with your Manager's address
3. Save your blend files in the shared storage location
### 6. Submit Renders ### Core Architecture
Submit render jobs directly through Blender's Output Properties panel using the Flamenco add-on. - **Manager**: Central coordination server (Go + SQLite) - orchestrates jobs, manages workers, serves web UI
- **Worker**: Task execution daemon - runs on render machines, executes Blender/FFmpeg commands
- **Add-on**: Blender integration (Python) - seamless job submission from within Blender
## Key Features ### Production Capabilities
- **Enterprise Scale**: Coordinate hundreds of workers across heterogeneous infrastructure
- **Zero-Configuration**: Minimal setup required for production deployment
- **Real-time Monitoring**: Live job status, worker health, performance metrics via modern web UI
- **Intelligent Scheduling**: Advanced task distribution with worker tagging and failure recovery
- **Zero Configuration**: Requires almost no setup for production use ---
- **Cross-Platform**: Windows, Linux, and macOS (including Apple Silicon)
- **Self-Hosted**: Complete control over your data and infrastructure
- **Job Types**: Customizable job types defined via JavaScript compiler scripts
- **Web Interface**: Monitor and manage renders through a modern Vue.js web UI
- **Variable System**: Multi-platform variables for handling different file paths
- **Asset Management**: Optional Shaman storage system for efficient asset sharing
- **Worker Management**: Tags, sleep scheduling, and task assignment
- **Real-time Updates**: Socket.io for live job and task status updates
## Architecture ## ⚡ Quick Start - Docker (Recommended)
Flamenco consists of three main components: Get Flamenco running in **under 10 minutes** with our optimized Docker environment:
- **Flamenco Manager**: Central coordination server built with Go and SQLite
- **Flamenco Worker**: Task execution daemon that runs on rendering machines
- **Blender Add-on**: Python plugin for submitting render jobs from within Blender
### Job Types & Variables
- **Job Types**: Defined by JavaScript compiler scripts that convert jobs into executable tasks
- **Variables**: Platform-specific configuration (e.g., different Blender paths for Windows/Linux/macOS)
- **Task Types**: Standard types include `blender`, `ffmpeg`, `file-management`, and `misc`
## Development

---
## 🏗️ Traditional Setup
### Native Development Environment
```bash
# Prerequisites: Go 1.24+, Node.js 22 LTS, Yarn, Java 11+
git clone https://projects.blender.org/studio/flamenco.git
cd flamenco
# Install dependencies and build tools
go run mage.go installDeps go run mage.go installDeps

``` ```
### Build System ### End-User Installation
Flamenco uses **Mage** as the primary build tool, wrapped by a Makefile: 1. **Download** from [flamenco.blender.org/download](https://flamenco.blender.org/download/) - contains Manager + Worker binaries
2. **Configure shared storage** accessible by all render machines
3. **Run Manager** → Use Setup Assistant to configure your farm
4. **Install Blender Add-on** → Download from Manager web interface
5. **Submit jobs** directly from Blender's Output Properties

## 🔧 Advanced Build System
### Mage Build Targets
```bash ```bash
make webapp-static # Build Vue.js webapp and embed in manager go run mage.go -l # List all available targets
make test # Run all tests go run mage.go build # Build manager and worker with webapp
make generate # Generate code (Go, Python, JavaScript APIs) go run mage.go check # Run comprehensive test suite
make format # Format all code go run mage.go generate # Generate API clients (Go/Python/JavaScript)
go run mage.go format # Format all code
go run mage.go clean # Clean build artifacts
``` ```
### Project Structure ### Docker Development Commands
- `cmd/` - Main entry points for binaries ```bash
- `internal/manager/` - Manager-specific code (job scheduling, API, persistence) make -f Makefile.docker dev-start # Start development environment
- `internal/worker/` - Worker-specific code (task execution) make -f Makefile.docker dev-tools # Start Vue.js/Hugo dev servers
- `pkg/` - Public Go packages (API, utilities, shared components) make -f Makefile.docker dev-logs # View service logs
- `web/app/` - Vue.js 3 webapp with TypeScript and Vite make -f Makefile.docker dev-stop # Stop all services
- `addon/` - Python Blender add-on with Poetry dependency management make -f Makefile.docker dev-clean # Clean environment and volumes
