Lattice Modifier for Unity

📖 Documentation

💢 New Features in 1.3 💢

Masking

Use material, vertex color/uv, or a texture to fine tune how Lattices are applied across your mesh.

Selection Falloff

Move, rotate, or scale nearby handles. Similar to 'Proportional Editing' in Blender or 'Soft Selection' in Maya.

Transform Lattice Modifier

Apply deformations to non-mesh objects, such as lights, particles emitters or any other transforms.

Improved Performance

Refactored compute shader with significant performance improvement, especially on lower-end targets such as phones.

And more!

Fit to renderer, interpolation types, and save mesh. Check the changelog to see the full feature list in 1.3!

⭐ Key Features

Easy to Use

Create a Lattice and add a modifier to your model. Move the points of the Lattice around to deform your mesh.

Animatable

Lattices can be keyframed and controlled with the animation timeline.

Scriptable

Lattices can be controlled with scripts for more advanced effects and interactivity.

Static and Skinned

Supports deforming both static and skinned meshes. Lattices can be applied before or after skinning.

Performant

Uses compute shaders for super-fast performance on par with GPU skinning and vertex shaders; far faster than editing the meshes in C#.

Samples Provided

Includes demo animations, shaders and scripts.

👾 Additional Features

Custom Editor

For intuitive editing of lattices, it supports a wide number of features, including move, scale, rotate, multiselect, selection falloff, fit to renderer, and undo & redo.

Works with Existing Materials

Use any existing materials, no custom shaders needed.

Squish and Stretch

Can access the amount of squish and stretch in your own shaders allowing you to create even more advanced effects!

Per Lattice Settings

Can toggle between high quality and fast sampling methods to improve performance if needed, and between global and local/restrained deformation.

Transform Modifier

Apply deformation to Transform components, to allow deformation of non-mesh objects such as lights, particle emitters or other GameObjects.

Save Deformed Meshes

Save deformed meshes as assets in the editor or get a copy of the mesh via scripts.
