A material for drawing geometries in a simple shaded (flat or wireframe) way.

This material is not affected by any lights.


MeshBasicMaterial(parameters : Object)

parameters — (optional) an object with one or more properties defining the material's appearance. Any property of the material (including any property inherited from Material) can be passed in here.

The exception is the property color, which can be passed in as a hexadecimal string and is 0xffffff (white) by default. Color.set(color) is called internally.

Instead of creating basic materials with JavaScript, it can be more efficient to simply make such materials in Blender, 3ds Max, or Maya.


See the base Material class for common properties.

.alphaMap : Texture

The alpha map is a grayscale texture that controls the opacity across the surface (black: fully transparent; white: fully opaque). Default is null.

Only the color of the texture is used, ignoring the alpha channel if one exists. For RGB and RGBA textures, the WebGL renderer will use the green channel when sampling this texture due to the extra bit of precision provided for green in DXT-compressed and uncompressed RGB 565 formats. Luminance-only and luminance/alpha textures will also still work as expected.

.aoMap : Texture

The red channel of this texture is used as the ambient occlusion map. Default is null. The aoMap requires a second set of UVs.

.aoMapIntensity : Float

Intensity of the ambient occlusion effect. Default is 1. Zero is no occlusion effect.

.color : Color

Color of the material, by default set to white (0xffffff).

.combine : Integer

How to combine the result of the surface's color with the environment map, if any.

Options are v3d.MultiplyOperation (default), v3d.MixOperation, v3d.AddOperation. If mix is chosen, the .reflectivity is used to blend between the two colors.

.envMap : Texture

The environment map. Default is null.

.fog : Boolean

Whether the material is affected by fog. Default is true.

.lightMap : Texture

The light map. Default is null. The lightMap requires a second set of UVs.

.lightMapIntensity : Float

Intensity of the baked light. Default is 1.

.map : Texture

The color map. May optionally include an alpha channel, typically combined with .transparent or .alphaTest. Default is `null.

.reflectivity : Float

How much the environment map affects the surface; also see .combine. The default value is 1 and the valid range is between 0 (no reflections) and 1 (full reflections).

.refractionRatio : Float

The index of refraction (IOR) of air (approximately 1) divided by the index of refraction of the material. It is used with environment mapping modes v3d.CubeRefractionMapping and v3d.EquirectangularRefractionMapping. The refraction ratio should not exceed 1. Default is 0.98.

.specularMap : Texture

Specular map used by the material. Default is null.

.wireframe : Boolean

Render geometry as wireframe. Default is false (i.e. render as flat polygons).

.wireframeLinewidth : Float

Controls wireframe thickness. Default is 1.

Due to limitations of the OpenGL Core Profile with the WebGL renderer on most platforms linewidth will always be 1 regardless of the set value.
