Choose which objects a light affects.
Use light linking in Tesseract to light a product, background or detail separately. Ask your agent to control object illumination and shadow relationships.
Rendered in Tesseract with path tracing at 32 samples per pixel. Download the editable project to revise the scene.

A prompt to start from
Build a Tesseract scene with a product and a separate background. Add a warm light that affects only the product and a cool light for the background. Render a preview, then adjust the product’s highlight without changing the background. Preserve the object positions, camera and animation, and keep the light links editable.

Keep control of the result.
- Included objects
- Choose the scene items that receive a light’s illumination.
- Excluded objects
- Keep a background or other approved object outside a lighting change.
- Shadow relationships
- Control supported shadow-casting and receiving relationships.
- Review by renderer
- Inspect linked illumination and optical shadows using the renderer selected for export.
A few useful details.
Why use linking instead of moving the light?
Moving a light changes its angle and the highlights it creates. Linking lets you retain that placement while limiting which objects it affects.
Does linking work exactly the same in raster and path tracing?
No. Some optical and shadow-link behavior differs. Check the actual scene with the intended renderer before delivery.
Can it isolate part of a single object?
Linking acts on supported scene objects and relationships. If a detail needs independent lighting control, the agent may need to represent it as a separate scene item.
How do I try this with my agent?
Install or update Tesseract in a supported agent, attach your source files, and copy the prompt. Review the preview, then ask for the changes you want. The composition stays editable as you refine it.
Where does the video render?
Tesseract renders in the environment where your agent runs it, including supported local computers and hosted Linux environments. The engine is free; your agent’s subscription or usage costs are separate.

Read the prompt
Set up Tesseract by Mirage so you can create editable designs and 3D scenes, edit videos, and make motion graphics in this agent’s environment. Read https://github.com/mirage-hq/Tesseract and check the requirements for this local or hosted environment. If it is supported, follow the official plugin or skills installation guide, use its required runtime version, verify the download checksum, and confirm a short preview renders correctly. Then ask what I want to make and which brand references or source assets I have. Keep the editable project and source assets with the finished render.
