ComfyUI Production Pipeline
I designed a repeatable ComfyUI process for creating, reviewing, cleaning, and exporting media used across game prototypes, mods, and tabletop tools.
At a glance
Role
Workflow designer, prompt author, and asset-cleanup owner
Used In
Character concepts, material tests, mod assets, and presentation media
Technical Focus
Repeatable workflows, queued jobs, review points, metadata, and export steps
Repository Rule
Large models, private prompts, and generated output stay outside public Git repositories
Technical Focus
The engineering work sits around image generation: recording workflow metadata, keeping private and public files separate, routing jobs, adding review points, and preparing selected output for use in a project.
Pipeline Shape
Prompt + Workflow Registry
Each job records its workflow, prompt template, output category, and visibility before it enters the generation queue.
Local Job Routing
A router prepares each request, validates its workflow metadata, and stores outputs outside the public repository.
Asset Preparation
Game and mod assets move through mask extraction, layer cleanup, contact sheets, scale checks, UI bakes, and source labeling.
Workflow Screenshots
Saved ComfyUI graphs show the reusable stages behind each output: references, prompts, masks, samplers, cleanup, upscaling, and export.
Ronin Identity Workflow
A larger character workflow for keeping identity, pose, and style constraints organized across base, advanced, and upscale passes.
Dahaka Cleanup Graph
A compact cleanup graph for background extraction, mask combination, eraser-style repair, alpha joining, and final sheet export.
Flux/Klein Enhancer
Enhancement, denoising, and export are separated into visible stages that can be adjusted independently.
One Cleanup Example
A Prince source image moves through mask extraction and cleanup before it is organized for use in the mod and its presentation materials.
Raw Source Sheet
Source sheet: generated/source material is treated as raw production input, not a finished game asset.
Mask Extraction
BiRefNet pass: background removal isolates the character and component pieces for downstream cleanup.
Final Clean Sheet
Final clean sheet: the output is organized enough to become reference, matte source, or presentation material.
Shogun Character Reference
A cleaner Shogun production asset used as the kind of source/reference material that can move through local ComfyUI cleanup and variant workflows.
Shogun Environment Source
Environment art from the Shogun folder shows how the workflow extends beyond character-only examples.
Shogun Sprite Cleanup Target
Sprite/action material is where the pipeline becomes practical: alpha, consistency, scale, and downstream implementation matter more than one flashy render.
Local Workflow Router
Projects submit media requests through a small routing layer. The router selects a saved workflow, validates prompt metadata, sends the job to ComfyUI, and stores the result outside the public repository.
-> workflow + prompt template selected
-> GM approves or edits
-> Comfy router prepares job
-> ComfyUI renders locally
-> output stored outside Git
Scene Reveal
Player-visible fantasy scene illustration for campaign moments, routed as a background image job.
Portrait Variant
GM-only character portrait exploration for NPCs, player-facing reveals, and visual canon review.
Location Study
Environment stills focused on layout, landmarks, atmosphere, and table handouts.
Item Or Clue
Close-up prop and clue imagery used when an object needs more attention than a text description can carry.
AI Use And Ownership
I label ComfyUI-assisted visuals and distinguish them from the systems, interfaces, routing, cleanup, integration, and testing I completed.
Generated images support visual direction. My portfolio claims focus on the production decisions and implementation required to make those images usable.
What I Learned
Make AI output auditable
Each generated asset should record its workflow, storage location, visibility, and publication status.
Do not block live play on rendering
ComfyUI belongs behind queues, approvals, and fallback states. A stalled image job should not freeze a game session or derail a prototype demo.
Separate lookdev from implementation
Generated source material still needs clean layers, readable UI treatment, usable sprites, or a consistent visual direction.
