The local image is explicitly interpreted as an artistic luminance height field. Image gradients form surface normals, then a moving light changes diffuse and specular response without moving the source pixels or reconstructing a real object.

What you get

  1. A real 1280 × 720 MP4, poster, contact sheet and source-hash receipt

  2. Editable local JSON and the task-specific implementation

Good for

  • Engraved-material concepts and macro lighting studies.

Not for

  • Recovered real depth, calibrated reflectance or evidence that the depicted object exists.

How it works

Includes a local renderer

  1. Prepare the actual input

    An owned height-style image; the included koi panel is illustrative.

  2. Apply the supported controls

    Replace the source image or supplied height artwork. Set relief scale and material roughness. Choose the light-sweep angle.

  3. Build and review the result

    The video renderer streams frames locally, emits H.264/yuv420p with fast-start metadata, and is silent. Add separately authorized audio in an external edit only if requested.

How Raking Light Relief Film works

The local image is explicitly interpreted as an artistic luminance height field. Image gradients form surface normals, then a moving light changes diffuse and specular response without moving the source pixels or reconstructing a real object.

What's inside the skill

What you can change

  • Replace the source image or supplied height artwork.
  • Set relief scale and material roughness.
  • Choose the light-sweep angle.

What to review before delivery

  • The selftest changes relief scale and compares actual shaded pixels.
  • Inspect both ends of the sweep for clipped highlights and lost fine detail.

Why use this skill

Start with this package

The local image is explicitly interpreted as an artistic luminance height field. Image gradients form surface normals, then a moving light changes diffuse and specular response without moving the source pixels or reconstructing a real object. The package supplies the working example, bounded inputs and export route so these do not need to be designed from a plain prompt.

What PopNow adds

Use PopNow for the missing Images in this workflow. Keep adequate material you already own, then bring new assets back into the editing and assembly steps described here.

Compare the options

A prompt, your own skill, or this workflow?

Start with a prompt

Your agent can create from a plain request. The brief, visual rules, asset choices, output format and review process still need to be established for that project.

Write your own skill

You choose and maintain the reusable instructions, defaults, file structure and checks. This is useful when your process needs different rules or integrations.

A workflow created for PopNow

This workflow was built for PopNow. Its source files, included dependencies and applicable notices are part of the package; the scope described below belongs to this edition.

What will this cost?

The included original assets can be reused by the local builder. Replacing artwork or adding optional sound through PopNow requires a quote for that exact request. Local processing does not spend generation funds; the agent and external editing/viewing work are outside those generation charges.

Generation is optional when you have suitable input material. Free skill. New media is quoted before it runs.

The skill package

Free to install under your account's download allowance. The package license covers your own and client work; redistribution is excluded.

Existing assets and local work

Reusing suitable assets, editing files and running local assembly do not call a PopNow generation model. Your computer and any required runtime still do the work.

New AI images, clips or sound

Quoted for the actual model, inputs, count, duration and resolution. Extra alternatives, revisions or optional enhancement passes can add generation requests.

Your agent and hosting

Any subscription, hosted computer, deployment or other provider fee belongs to that service. Installing this skill does not include those services.

Check the cost of your version first

Your assistant can inspect the available models and quote the exact request first. You choose which optional passes to include and approve spending before generation.

Ask your assistant

  • Use the PopNow skill "Raking Light Relief Film" for my project. List the inputs you can reuse, quote only the missing media, show the quoted total and flag any unpriced steps. Separate optional enhancements, and wait for my approval before starting anything paid.

How PopNow billing works

Connections using a PopNow API key, including API-key MCP connections, spend from the separate API balance in USD. A ChatGPT or Claude connection authorized through OAuth spends website credits. These balances are separate; the quote shown by your connection is the approval basis.

Download allowances and current account conditions apply. A free package does not mean unlimited free generation.

How to use it

You say

  • Use the PopNow skill "Raking Light Relief Film" (raking-light-relief-film) for this: Sweep light across an artistic height field to reveal fine engraved texture, directional shading and metallic highlights. Start with the bundled project, make the requested edits and inspect the actual output.

Then try

  • Replace the source image or supplied height artwork.

  • Set relief scale and material roughness.

What to have ready

  • An owned height-style image; the included koi panel is illustrative.
  • Python, Pillow, NumPy and FFmpeg/ffprobe.

Questions

Does this recover the true 3D shape?

No. Luminance is treated as a creative height signal. A darker painted region can become a recess even if it would not be one on a real object.

Does the bundled example require paid generation?

No. The included assets or procedural inputs run locally. If you ask for new images, clips or sound, use PopNow with an exact quote and approval before generation; API USD and OAuth website credits are separate.

What is already packaged in Raking Light Relief Film?

Derives artistic surface normals from luminance and evaluates the moving light. Local validation, protected output and artifact construction. Runnable example with actual supported controls. Mechanism-specific limits and visual review criteria.

Which parts of Raking Light Relief Film can add a charge?

How does Raking Light Relief Film differ from writing a prompt or my own skill?

The local image is explicitly interpreted as an artistic luminance height field. Image gradients form surface normals, then a moving light changes diffuse and specular response without moving the source pixels or reconstructing a real object. The package supplies the working example, bounded inputs and export route so these do not need to be designed from a plain prompt.
