3D rendering with discrete light-value bands, bold silhouette outlines, and reduced gradients for a flat, hand-drawn look.

## Prompt seed

Cel-shaded rendering treatment with discrete light-value bands, bold silhouette outlines, and reduced gradients; a simple 3D scene with crisp contour edges, blocky shadow shapes, and minimal material blending.

## Using this seed

A reusable starting point; add your subject or details in your image tool. The example may have used extra directions and results will vary.

Mode: Make
An original generated example of this visual direction.

Limitation: A generated still rendering concept; no working shader, interactive scene or production-ready game asset is supplied.

## Example

Created with: OpenAI Image API
Model: gpt-image-2.5-flare
Image generated: 2026-10-15
Original OpenAI API image selected from research plan cel-shaded-rendering. Automated independent style review and visual review: Meets the requested cel-shaded style: discrete light bands, bold outlines, blocky shadows, and minimal gradients; square coherent scene with no visible text, watermark, or obvious defects, and not a near-copy of the comparison samples. Exact and conservative perceptual duplicate checks passed against existing samples and this batch. Exported to 1200px and 640px WebP; source 1024px enlarged for full display. No human visual review.

## Light falls into distinct bands

Discrete light and shadow values replace a continuous gradient. Strong contours and simplified material transitions help the pavilion read more like a drawn image while retaining a sense of three-dimensional form. The doorway variation applies the treatment to an enclosed room, with clear bands across the walls and floor.

This is a still rendering treatment. To make an interactive scene, implement and test the shader under changing lights and camera angles; the example image does not supply a working shader or game asset.


## Variation: Doorway light bands

A compact interior uses distinct light-value bands, bold contours and blocky shadows viewed through a doorway.

An enclosed doorway composition replaces the outdoor pavilion; discrete light bands and clear contour edges remain the visual language.

Prompt seed: Cel-shaded rendering treatment with discrete light-value bands, bold silhouette outlines, and reduced gradients; a simple 3D scene with crisp contour edges, blocky shadow shapes, and minimal material blending.

An original generated interpretation using a different composition.
Limitation: A still rendering interpretation, not an implemented shader or interactive game asset. The image does not demonstrate a numerically exact value-band system.
Original generated variant for the search audit. Clear outlined doorway geometry, broad separated light/shadow planes and restrained material colors are visible. Interior depth differs from the outdoor pavilion. Some subtle within-plane shading remains; do not claim a numerically exact three-band shader. Exact model and cost were not exposed. Requested 2048px; source returned 1254×1254px, reduced to 1200px and 640px WebP. The public seed summarizes the style/sample direction; the full request also includes composition instructions. No claim that the public seed alone reproduces the image. Assistant review, not human specialist approval.
