What is houdini-pro-workflows?

SideFX Houdini FlowBridge is a community-built pipeline orchestration tool designed to extend how the 3D VFX software Houdini connects with external systems. Houdini, made by SideFX, is widely used in professional visual effects for films and games to simulate fire, water, destruction, and other complex phenomena. FlowBridge positions itself as a layer on top of Houdini that lets each part of a workflow consult external services, adapt to hardware, and communicate with other tools. The tool connects Houdini's internal node-based workflow to AI language model APIs, including OpenAI and Claude. An artist can describe a desired effect in plain text, and FlowBridge generates the corresponding Houdini node network. When a simulation crashes, the tool captures the error log and sends it to an AI model to suggest or apply a fix. A separate creative variation feature can produce multiple stylistic versions of an asset by combining AI-generated reference images with Houdini's procedural parameters. Other features include real-time synchronization between Houdini and other 3D tools via USD, a common scene exchange format used across the industry. A background monitoring daemon watches simulation caches, node errors, and disk space, sending alerts by webhook or email. Simulation work such as fluid, fire, and rigid body calculations can be distributed across multiple GPUs or networked machines without manual configuration. The interface supports multiple languages and is designed to scale from a single large monitor to multi-screen environments. Configuration is done through a YAML file where users set memory limits, choose AI models, define output paths, and set the interface theme. The project ships a sample configuration and command-line invocation examples for headless or farm-style workflows.
