Animate a model’s shape changes.

Adjust imported morph targets and native mesh shape keys with Tesseract. Use your agent to blend shapes, revise weights and preserve the base project.

A prepared GLB morph target reshapes the same mesh from a narrow form to a wider, lobed form. The target weight remains editable.

Rendered in Tesseract with path tracing at 16 samples per pixel. Download the editable project to revise the scene.

Give your agent this .tsrct file, then ask for a specific change.

Try it in your agent.

Use this prompt as a starting point. Review the result, then ask for the details you want to change.

A prompt to start from

Use Tesseract to animate a supplied model between two compatible morph states. Keep the camera and lighting fixed so the shape change is easy to judge. Render preview frames at the start, middle and end. If the middle looks distorted, adjust only the weights and transition timing. Preserve the base mesh and approved end states.

Keep control of the result.

Imported morph weights
Control supported morph targets from an imported model.
Native shape keys
Create and edit shape offsets on a native editable mesh.
Corrective shapes
Use supported corrective shape keys for a specific deformation state.
Animation and sculpting
Animate weights or sculpt a native shape key without replacing the base geometry.

A few useful details.

Are imported morphs and native shape keys the same workflow?

They serve related purposes but have different authoring paths. Imported models expose their morph weights; native editable meshes support authored shape keys and corrective shapes.

Can I use this for facial animation?

If the model contains suitable morph targets, their weights can be animated. This is not a promise of automatic facial rigging, lip sync or expression recognition.

Can I add detail by sculpting a shape key?

Yes, on supported native editable meshes. The sculpting operations preserve topology, so add sufficient geometry before attempting fine details.

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.

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.
