How do I change which eight angles are generated?

Edit the PrimitiveStringMultiline node. Replace or reorder the angle directives to match the views you need. The workflow will generate one image per line, then assemble all eight into the contact sheet.

Do I have to use GeminiImage2Node?

No. GeminiImage2Node (gemini-3-pro-image-preview) is an optional helper for deriving captions or angle hints from the editorial reference. You can rely entirely on the manual directives in PrimitiveStringMultiline if you prefer full control.

How does the workflow maintain product consistency?

Consistency comes from using the same product image input and a tightly scoped set of prompts with Nano Banana Pro. Keep the product image clean and well-lit, avoid overly creative modifiers, and reuse a fixed seed if you want stricter repeatability.

Can I export individual images instead of only a contact sheet?

Yes. BatchImagesNode passes each frame to SaveImage. You can keep both the 8-up grid and the individual frames, or disable the grid output path if you only want separate images.

Step 2: Contact Sheet Workflow

This ComfyUI workflow builds a fast, repeatable contact-sheet generator for fashion products. You provide two inputs—a fashion editorial reference and a clean product image—and the graph produces eight distinct angle variations while preserving product identity. The pipeline pivots on Nano Banana Pro for image generation and uses a small, consistent set of prompts to drive variety without drifting from the product look. Outputs are compiled into a vertical 9:16 contact sheet at 4K resolution (2160x3840) for quick review or social/merchandising handoff.

Technically, the graph uses LoadImage to bring in your editorial reference and product packshot. A PrimitiveStringMultiline node holds the eight angle directives (you can edit these to change viewpoints), while a PrimitiveNode stores simple numeric settings (such as the number of angles or seeds). GeminiImage2Node (configured for gemini-3-pro-image-preview) can be used as a helper to analyze the editorial reference or produce caption text that feeds into your prompt block. Two essentials nodes (UUIDs 68c58c16-e698-45a4-97f9-54ae8eb9dee9 and 487baed2-dc27-49c3-a6b2-0bf45a53e64d from comfyui_essentials) handle image collation and layout with BatchImagesNode assembling the eight results, RegexReplace cleaning file names, and SaveImage writing a single 8-up contact sheet plus optional individual frames. The result is a compact, reliable step that expands only two Nano Banana generations into eight consistent angles.

API

Use this workflow from code

Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.

template_contact_sheet-step_2.app.json

Fetching workflow JSON…

Run it from TypeScript or Python with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.

// Install (beta)
npm i @comfyorg/sdk

// Run "Step 2: Contact Sheet Workflow" (TypeScript)
import { Comfy } from "@comfyorg/sdk";

const client = new Comfy({ apiKey: "comfyui-..." });

// This workflow, exported in API format (see note below)
const wf = await client.workflows.fromFile("template_contact_sheet-step_2.app_api.json");

const asset = client.assets.fromFile("input.png");
wf.setInput("16", "image", asset);  // LoadImage

const job = await client.run(wf);
await job.getOutputs("88")[0].toFile("output.png");  // SaveImage

The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API).

Comfy Cloud API access requires a plan with an API key.
