Playbook

Translates ComfyUI node-based workflows directly into 3D scene definitions by parsing the node graph structure, resolving data flow between nodes, and mapping output tensors (images, latents, conditioning) to 3D asset parameters. This eliminates manual export/import cycles by maintaining a live connection between generative AI pipeline outputs and 3D composition, automatically updating scenes when upstream nodes change.

Enables placement and arrangement of 3D objects (primitives, imported meshes, procedurally generated geometry) within a scene, with automatic texture application from ComfyUI-generated images. Supports UV mapping, material assignment, and real-time preview of how AI-generated textures wrap onto 3D geometry, allowing designers to iterate on material appearance without leaving the tool.

Maintains a history of scene changes with undo/redo functionality, allowing users to revert to previous states. Optionally supports scene versioning where named snapshots can be saved and restored. Useful for exploring different composition options and reverting to a known good state if changes don't work out.

Establishes two-way data binding between 3D scene parameters (camera position, object transforms, lighting intensity) and ComfyUI node inputs (seed, sampler steps, LoRA strength, controlnet conditioning). Changes to scene properties automatically propagate to ComfyUI nodes, triggering re-evaluation and updating the 3D viewport with new AI-generated outputs. Supports parameterized workflows where adjusting a 3D slider updates the generative pipeline.

Provides a WebGL or GPU-accelerated 3D viewport that renders scenes composed of AI-generated textures and geometry in real-time. Supports camera manipulation (orbit, pan, zoom), lighting adjustments, and material preview modes. The viewport updates live as ComfyUI outputs change, allowing designers to see the impact of generative parameter changes immediately without waiting for export/import cycles.

Exports composed 3D scenes to industry-standard formats (likely .glb, .fbx, .obj) and optionally to rendering engines (Unreal, Unity, Three.js) for further refinement or deployment. Preserves material assignments, texture references, and object hierarchy during export. Supports batch export of multiple scene variations generated from ComfyUI parameter sweeps.

Automates creation of multiple scene variations by sweeping ComfyUI node parameters (seed, sampler steps, LoRA weights) and generating a new scene for each parameter combination. Playbook orchestrates the parameter sweep, triggers ComfyUI re-generation for each combination, and composes the resulting outputs into separate scenes. Useful for exploring design variations or creating animation frames.

Allows registration and use of custom ComfyUI nodes within Playbook workflows, including community nodes, LoRA loaders, controlnet processors, and user-defined nodes. Playbook introspects custom node signatures (inputs, outputs, parameters) and exposes them in the UI for configuration. Supports nodes that generate images, conditioning, latents, or other data types that feed into 3D composition.

Organizes 3D objects into hierarchical groups and layers, enabling efficient management of complex scenes with many assets. Supports parent-child relationships, layer visibility toggling, and batch operations on grouped objects (transform, material assignment, visibility). Hierarchy is preserved during export and can be used to organize AI-generated assets by type or generation source.

Provides tools for configuring camera position, field of view, and depth-of-field, as well as lighting setup (directional lights, point lights, ambient lighting). Supports saving and loading camera/lighting presets for quick switching between different viewing angles and lighting scenarios. Presets can be parameterized and linked to ComfyUI inputs for dynamic lighting control.

Provides UI controls for adjusting material properties (metallic, roughness, normal map intensity, emissive strength) with real-time viewport updates. Changes to material parameters are immediately visible in the 3D viewport without requiring re-generation or re-import. Supports material variants where different parameter sets can be saved and swapped for the same texture.
