DefaultMaterial QML Type

This property determines how the colors of the model rendered blend with those behind it.

See also Qt Quick 3D Architecture.

This property controls the amount of simulated displacement for the bumpMap or normalMap. The default value is 0 disabling the bump effect. The range is [0, 1].

This property defines a grayscale Texture to simulate fine geometry displacement across the surface of the material. Brighter pixels indicate raised regions. The amount of the effect is controlled by the bumpAmount property.

Note: bump maps will not affect the silhouette of a model.

This property determines the diffuse color (albedo) for the material. Setting the diffuse color to a black tint will create a purely-specular material (e.g. metals or mirrors).

This property determines the amount of light wrap for the translucency map. A value of 0 will not wrap the light at all, while a value of 1 will wrap the light all around the object.

This property defines a Texture to apply to the material. Using Texture with transparency will also apply the alpha channel as an opacity map.

This property determines the color of self-illumination for this material. If an emissive map is set, the x, y, and z components are used as factors (multipliers) for the R, G and B channels of the texture, respectively. The default value is (0, 0, 0) and it means no emissive contribution at all.

Note: Setting the lightingMode to DefaultMaterial.NoLighting means emissive Factor does not have an effect on the scene.

This property sets a RGB Texture to be used to specify the intensity of the emissive color.

See also emissiveFactor.

This property decreases head-on reflections (looking directly at the surface) while maintaining reflections seen at grazing angles. The default value is 0 disabling the fresnel effect.

This property controls what angles of reflections are affected by the fresnelPower. The default is 1.45. The value must be greater or equal to 1.0.

Note: No known material in the world have ior much greater than 3.0.

This property defines which lighting method is used when generating this material.

The default value is DefaultMaterial.FragmentLighting

When using DefaultMaterial.FragmentLighting, diffuse and specular lighting are calculated for each rendered pixel. Certain effects (such as a Fresnel or bump map) require DefaultMaterial.FragmentLighting to work.

When using DefaultMaterial.NoLighting no lighting is calculated. This mode is (predictably) very fast, and quite effective when image maps are used that do not need to be shaded by lighting.

This property determines the width of the lines rendered, when the geometry is using a primitive type of lines or line strips. The default value is 1.0. This property is not relevant when rendering other types of geometry, such as, triangle meshes.

Warning: Line widths other than 1 may not be suported at run time, depending on the underlying graphics API. When that is the case, the request to change the width is ignored. For example, none of the following can be expected to support wide lines: Direct3D, Metal, OpenGL with core profile contexts.

Note: Unlike most other material properties, the line width is under the hood baked in to a graphics pipeline object, similarly to blendMode. Therefore, a different value leads to having to create a new pipeline object, which over time can become costly (performance and resource usage) if the property is frequently changed to many different values. For example, animating this property is possible, but should be avoided.

This property defines a RGB image used to simulate fine geometry displacement across the surface of the material. The RGB channels indicate XYZ normal deviations. The amount of the effect is controlled by the bumpAmount property.

Note: Normal maps will not affect the silhouette of a model.

This property drops the opacity of just this material, separate from the model. The default is 1.0. The range is [0.0, 1.0].

This property defines the texture channel used to read the opacity value from opacityMap. The default value is Material.A.

This property defines a Texture used to control the opacity differently for different parts of the material.

This property determines the size of the points rendered, when the geometry is using a primitive type of points. The default value is 1.0. This property is not relevant when rendering other types of geometry, such as, triangle meshes.

Warning: Point sizes other than 1 may not be supported at run time, depending on the underyling graphics API. For example, setting a size other than 1 has no effect with Direct 3D.

This property defines the texture channel used to read the roughness value from roughnessMap. The default value is Material.R.

This property defines a Texture to control the specular roughness of the material. If the texture contains multiple channels(RGBA), then the correct channel can be set using the roughnessChannel property.

This property controls the strength of specularity (highlights and reflections). The default value is 0 disabling the specularity. The range is [0.0, 1.0].

Note: This property does not affect the specularReflectionMap, but does affect the amount of reflections from a scene's SceneEnvironment::lightProbe.

Note: Unless your mesh is high resolution, you may need to use DefaultMaterial.FragmentLighting to get good specular highlights from scene lights.

This property defines a RGB Texture to modulate the amount and the color of specularity across the surface of the material. These values are multiplied by the specularAmount.

This property determines which functions are used to calculate specular highlights for lights in the scene.

This property sets a Texture used for specular highlights on the material.

This is typically used to perform environment mapping: as the model is rotated, the map will appear as though it is reflecting from the environment. For this to work as expected, the Texture's mappingMode needs to be set to Texture.Environment. Specular reflection maps are an easy way to add a high-quality look with a relatively low cost.

Note: Associating a light probe with the SceneEnvironment, and thus relying on image-based lighting, can achieve similar environmental reflection effects. Light probes are however a conceptually different, and when it comes to performance, potentially more expensive solution. Each approaches have their own specific uses, and the one to use needs to be decided on a case by case basis. When it comes to the Texture set to the property, specularReflectionMap has an advantage, because it presents no limitations and supports all types of textures, including ones that source their data from a Qt Quick sub-scene via sourceItem.

Note: Crisp images cause your material to look very glossy; the more you blur your image the softer your material will appear.

See also Texture::mappingMode.

This property controls the size of the specular highlight generated from lights, and the clarity of reflections in general. Larger values increase the roughness, softening specular highlights and blurring reflections. The range is [0.0, 1.0]. The default value is 0.

This property defines a color used to adjust the specular reflections. Use white for no effect

This property defines the texture channel used to read the translucency value from translucencyMap. The default value is Material.A.

This property defines a grayscale Texture controlling how much light can pass through the material from behind.

This property defines the amount of falloff for the translucency based on the angle of the normals of the object to the light source.

When this property is enabled, the material will use vertex colors from the mesh. These will be multiplied by any other colors specified for the material.
