Components

Lattice

Lattices are the 3d grid used to control deformations. Take a look at using Lattices for guides on editing, animating and scripting Lattices.

Lattices have the following properties:

Resolution
The number of handles across each axis.

Lattice Modifier

Lattice Modifiers allow static meshes to be affected by Lattices. Lattice Modifiers must be added to GameObjects with a MeshFilter and MeshRenderer. You can apply multiple Lattices to a Lattice Modifier.

Lattice Modifiers have the following properties:

Target Mesh
The mesh used on the attached Mesh Filter component. This field will be automatically filled in when added to the GameObject.
Stretch Target
The UV channel to add squish and stretch to. If set to None, stretch and squish will not be accessible in shaders.
Update Mode
How often the Lattices are applied. You can change this at runtime with the property UpdateMode. Can choose from the following options:
- Manual
  Only applied on start, or if RequestUpdate() is called on the component.
- When Visible
  Updates every frame when the MeshRenderer is visible.
- Always
  Updates every frame.
Lattices
The Lattices to apply to this modifier. Each has the following additional properties:
- High Quality
  Increases the quality of deformation, but uses more computation. Take a look at the Quality sample for an example of the visual difference.
- Global
  Will continue to apply deformations outside of the Lattice. If disabled, deformations are restrained to near the Lattice.

Skinned Lattice Modifier

Skinned Lattice Modifiers allow skinned meshes to be affected by Lattices. Skinned Lattice Modifiers must be added to a GameObject with a Skinned Mesh Renderer. You can apply multiple Lattices to a Skinned Lattice Modifier, and choose to apply them before or after skinning.

Skinned Lattice Modifiers have the following properties:

Target Mesh
The mesh used on the attached Skinned Mesh Renderer component. This field will be automatically filled in when added to the GameObject.
Stretch Target
The UV channel to add squish and stretch to. If set to None, stretch and squish will not be accessible in shaders.
Update Mode
How often the pre-skinning Lattices are applied. The Skinned Lattices are not affected by this option, and are updated whenever skinning is updated. You can change this at runtime with the property UpdateMode. Can choose from the following options.
- Manual
  Only applied on start, or if RequestUpdate() is called on the component.
- When Visible
  Updates every frame when the SkinnedMeshRenderer is visible.
- Always
  Updates every frame.
Lattices
The Lattices to apply before skinning. Each has the following additional properties:
- High Quality
  Increases the quality of deformation, but uses more computation. Take a look at the Quality sample for an example of the visual difference.
- Global
  Will continue to apply deformations outside of the Lattice. If disabled, deformations are restrained to near the Lattice.
Skinned Lattices
The Lattices to apply after skinning. They have the same additional properties as the other Lattice lists.

Tip

It can be hard to determine how Lattices applied before skinning affect your character, especially if their rig has moved from their bind pose.

A quick way to get a reference of their pre-skinning position is to create a child GameObject under your Skinned Mesh Renderer, add a Mesh Filter and Mesh Renderer, and copy the target mesh and materials across. This will display your character in their bind pose which you can use as reference.
