UnlitMaterial class

A material that draws geometry with a flat color or texture, ignoring scene lighting.

Useful for UI overlays, debug visualization, or stylized rendering. The final color is baseColorFactor * baseColorTexture, optionally blended with the per-vertex color via vertexColorWeight.

Wraps the UnlitFragment shader from baseShaderLibrary.

Constructors

UnlitMaterial({Texture? colorTexture})

Creates an UnlitMaterial, optionally textured.

Properties

baseColorFactor ↔ Vector4

Linear RGBA tint multiplied with baseColorTexture.

getter/setter pair

baseColorTexture ↔ Texture

The base color texture, sampled and multiplied by baseColorFactor.

getter/setter pair

doubleSided ↔ bool

Whether to render both faces of triangles drawn with this material (glTF's material.doubleSided). When true, bind disables back-face culling so the geometry is visible from both sides; otherwise back faces are culled. Defaults to false. The runtime importer sets it from the glTF material.

getter/setter pair, inherited

fragmentShader → Shader

The fragment shader used when rendering geometry with this material.

no setter, inherited

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

vertexColorWeight ↔ double

How strongly per-vertex colors influence the final color. 0 disables vertex color contribution; 1 (the default) fully applies it.

getter/setter pair

Methods

bind(RenderPass pass, HostBuffer transientsBuffer, Lighting lighting) → void

Binds this material's render-pass state, uniforms, and textures.

override

isOpaque() → bool

Whether geometry rendered with this material is fully opaque.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

setFragmentShader(Shader shader) → void

Assigns the fragment shader used when this material is drawn.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

fromFlatbuffer(Material fbMaterial, List<Texture> textures) → UnlitMaterial

Builds an UnlitMaterial from a flatbuffer material description, resolving texture indices against textures.
