Type members

• class var godotClassName: StringName

Instance members

• var albedoColor: Color

  The material’s base color.

• var albedoTexture: Texture2D?

  Texture to multiply by albedoColor. Used for basic texturing of objects.

• var albedoTextureForceSrgb: Bool

  If true, forces a conversion of the albedoTexture from sRGB color space to linear color space. See also vertexColorIsSrgb.

• var albedoTextureMsdf: Bool

  Enables multichannel signed distance field rendering shader. Use msdfPixelRange and msdfOutlineSize to configure MSDF parameters.

• var alphaAntialiasingEdge: Double

  Threshold at which antialiasing will be applied on the alpha channel.

• var alphaAntialiasingMode: BaseMaterial3D.AlphaAntiAliasing

  The type of alpha antialiasing to apply. See AlphaAntiAliasing.

• var alphaHashScale: Double

  The hashing scale for Alpha Hash. Recommended values between 0 and 2.

• var alphaScissorThreshold: Double

  Threshold at which the alpha scissor will discard values. Higher values will result in more pixels being discarded. If the material becomes too opaque at a distance, try increasing alphaScissorThreshold. If the material disappears at a distance, try decreasing alphaScissorThreshold.

• var anisotropy: Double

  The strength of the anisotropy effect. This is multiplied by anisotropyFlowmap’s alpha channel if a texture is defined there and the texture contains an alpha channel.

• var anisotropyEnabled: Bool

  If true, anisotropy is enabled. Anisotropy changes the shape of the specular blob and aligns it to tangent space. This is useful for brushed aluminium and hair reflections.

• var anisotropyFlowmap: Texture2D?

  Texture that offsets the tangent map for anisotropy calculations and optionally controls the anisotropy effect (if an alpha channel is present). The flowmap texture is expected to be a derivative map, with the red channel representing distortion on the X axis and green channel representing distortion on the Y axis. Values below 0.5 will result in negative distortion, whereas values above 0.5 will result in positive distortion.

• var aoEnabled: Bool

  If true, ambient occlusion is enabled. Ambient occlusion darkens areas based on the aoTexture.

• var aoLightAffect: Double

  Amount that ambient occlusion affects lighting from lights. If 0, ambient occlusion only affects ambient light. If 1, ambient occlusion affects lights just as much as it affects ambient light. This can be used to impact the strength of the ambient occlusion effect, but typically looks unrealistic.

• var aoOnUv2: Bool

  If true, use UV2 coordinates to look up from the aoTexture.

• var aoTexture: Texture2D?

  Texture that defines the amount of ambient occlusion for a given point on the object.

• var aoTextureChannel: BaseMaterial3D.TextureChannel

  Specifies the channel of the aoTexture in which the ambient occlusion information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored metallic in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.

• var backlight: Color

  The color used by the backlight effect. Represents the light passing through an object.

• var backlightEnabled: Bool

  If true, the backlight effect is enabled. See also subsurfScatterTransmittanceEnabled.

• var backlightTexture: Texture2D?

  Texture used to control the backlight effect per-pixel. Added to backlight.

• var billboardKeepScale: Bool

  If true, the shader will keep the scale set for the mesh. Otherwise, the scale is lost when billboarding. Only applies when billboardMode is not .billboardDisabled.

• var billboardMode: BaseMaterial3D.BillboardMode

  Controls how the object faces the camera. See BillboardMode.

• var blendMode: BaseMaterial3D.BlendMode

  The material’s blend mode.

• var clearcoat: Double

  Sets the strength of the clearcoat effect. Setting to 0 looks the same as disabling the clearcoat effect.

• var clearcoatEnabled: Bool

  If true, clearcoat rendering is enabled. Adds a secondary transparent pass to the lighting calculation resulting in an added specular blob. This makes materials appear as if they have a clear layer on them that can be either glossy or rough.

• var clearcoatRoughness: Double

  Sets the roughness of the clearcoat pass. A higher value results in a rougher clearcoat while a lower value results in a smoother clearcoat.

• var clearcoatTexture: Texture2D?

  Texture that defines the strength of the clearcoat effect and the glossiness of the clearcoat. Strength is specified in the red channel while glossiness is specified in the green channel.

• var cullMode: BaseMaterial3D.CullMode

  Determines which side of the triangle to cull depending on whether the triangle faces towards or away from the camera. See CullMode.

• var depthDrawMode: BaseMaterial3D.DepthDrawMode

  Determines when depth rendering takes place. See DepthDrawMode. See also transparency.

• var detailAlbedo: Texture2D?

  Texture that specifies the color of the detail overlay. detailAlbedo’s alpha channel is used as a mask, even when the material is opaque. To use a dedicated texture as a mask, see detailMask.

• var detailBlendMode: BaseMaterial3D.BlendMode

  Specifies how the detailAlbedo should blend with the current ALBEDO. See BlendMode for options.

• var detailEnabled: Bool

  If true, enables the detail overlay. Detail is a second texture that gets mixed over the surface of the object based on detailMask and detailAlbedo’s alpha channel. This can be used to add variation to objects, or to blend between two different albedo/normal textures.

• var detailMask: Texture2D?

  Texture used to specify how the detail textures get blended with the base textures. detailMask can be used together with detailAlbedo’s alpha channel (if any).

• var detailNormal: Texture2D?

  Texture that specifies the per-pixel normal of the detail overlay. The detailNormal texture only uses the red and green channels; the blue and alpha channels are ignored. The normal read from detailNormal is oriented around the surface normal provided by the Mesh.

• var detailUvLayer: BaseMaterial3D.DetailUV

  Specifies whether to use UV or UV2 for the detail layer. See DetailUV for options.

• var diffuseMode: BaseMaterial3D.DiffuseMode

  The algorithm used for diffuse light scattering. See DiffuseMode.

• var disableAmbientLight: Bool

  If true, the object receives no ambient light.

• var disableFog: Bool

  If true, the object will not be affected by fog (neither volumetric nor depth fog). This is useful for unshaded or transparent materials (e.g. particles), which without this setting will be affected even if fully transparent.

• var disableReceiveShadows: Bool

  If true, the object receives no shadow that would otherwise be cast onto it.

• var distanceFadeMaxDistance: Double

  Distance at which the object appears fully opaque.

• var distanceFadeMinDistance: Double

  Distance at which the object starts to become visible. If the object is less than this distance away, it will be invisible.

• var distanceFadeMode: BaseMaterial3D.DistanceFadeMode

  Specifies which type of fade to use. Can be any of the DistanceFadeModes.

• var emission: Color

  The emitted light’s color. See emissionEnabled.

• var emissionEnabled: Bool

  If true, the body emits light. Emitting light makes the object appear brighter. The object can also cast light on other objects if a VoxelGI, SDFGI, or LightmapGI is used and this object is used in baked lighting.

• var emissionEnergyMultiplier: Double

  Multiplier for emitted light. See emissionEnabled.

• var emissionIntensity: Double

  Luminance of emitted light, measured in nits (candela per square meter). Only available when ProjectSettings/rendering/lightsAndShadows/usePhysicalLightUnits is enabled. The default is roughly equivalent to an indoor lightbulb.

• var emissionOnUv2: Bool

  Use UV2 to read from the emissionTexture.

• var emissionOperator: BaseMaterial3D.EmissionOperator

  Sets how emission interacts with emissionTexture. Can either add or multiply. See EmissionOperator for options.

• var emissionTexture: Texture2D?

  Texture that specifies how much surface emits light at a given point.

• var fixedSize: Bool

  If true, the object is rendered at the same size regardless of distance.

• var grow: Bool

  If true, enables the vertex grow setting. This can be used to create mesh-based outlines using a second material pass and its cullMode set to .cullFront. See also growAmount.

• var growAmount: Double

  Grows object vertices in the direction of their normals. Only effective if grow is true.

• var heightmapDeepParallax: Bool

  If true, uses parallax occlusion mapping to represent depth in the material instead of simple offset mapping (see heightmapEnabled). This results in a more convincing depth effect, but is much more expensive on the GPU. Only enable this on materials where it makes a significant visual difference.

• var heightmapEnabled: Bool

  If true, height mapping is enabled (also called “parallax mapping” or “depth mapping”). See also normalEnabled. Height mapping is a demanding feature on the GPU, so it should only be used on materials where it makes a significant visual difference.

• var heightmapFlipBinormal: Bool

  If true, flips the mesh’s binormal vectors when interpreting the height map. If the heightmap effect looks strange when the camera moves (even with a reasonable heightmapScale), try setting this to true.

• var heightmapFlipTangent: Bool

  If true, flips the mesh’s tangent vectors when interpreting the height map. If the heightmap effect looks strange when the camera moves (even with a reasonable heightmapScale), try setting this to true.

• var heightmapFlipTexture: Bool

  If true, interprets the height map texture as a depth map, with brighter values appearing to be “lower” in altitude compared to darker values.

• var heightmapMaxLayers: Int32

  The number of layers to use for parallax occlusion mapping when the camera is up close to the material. Higher values result in a more convincing depth effect, especially in materials that have steep height changes. Higher values have a significant cost on the GPU, so it should only be increased on materials where it makes a significant visual difference.

• var heightmapMinLayers: Int32

  The number of layers to use for parallax occlusion mapping when the camera is far away from the material. Higher values result in a more convincing depth effect, especially in materials that have steep height changes. Higher values have a significant cost on the GPU, so it should only be increased on materials where it makes a significant visual difference.

• var heightmapScale: Double

  The heightmap scale to use for the parallax effect (see heightmapEnabled). The default value is tuned so that the highest point (value = 255) appears to be 5 cm higher than the lowest point (value = 0). Higher values result in a deeper appearance, but may result in artifacts appearing when looking at the material from oblique angles, especially when the camera moves. Negative values can be used to invert the parallax effect, but this is different from inverting the texture using heightmapFlipTexture as the material will also appear to be “closer” to the camera. In most cases, heightmapScale should be kept to a positive value.

• var heightmapTexture: Texture2D?

  The texture to use as a height map. See also heightmapEnabled.

• var metallic: Double

  A high value makes the material appear more like a metal. Non-metals use their albedo as the diffuse color and add diffuse to the specular reflection. With non-metals, the reflection appears on top of the albedo color. Metals use their albedo as a multiplier to the specular reflection and set the diffuse color to black resulting in a tinted reflection. Materials work better when fully metal or fully non-metal, values between 0 and 1 should only be used for blending between metal and non-metal sections. To alter the amount of reflection use roughness.

• var metallicSpecular: Double

  Adjusts the strength of specular reflections. Specular reflections are composed of scene reflections and the specular lobe which is the bright spot that is reflected from light sources. When set to 0.0, no specular reflections will be visible. This differs from the .specularDisabled SpecularMode as .specularDisabled only applies to the specular lobe from the light source.

• var metallicTexture: Texture2D?

  Texture used to specify metallic for an object. This is multiplied by metallic.

• var metallicTextureChannel: BaseMaterial3D.TextureChannel

  Specifies the channel of the metallicTexture in which the metallic information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored metallic in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.

• var msdfOutlineSize: Double

  The width of the shape outline.

• var msdfPixelRange: Double

  The width of the range around the shape between the minimum and maximum representable signed distance.

• var noDepthTest: Bool

  If true, depth testing is disabled and the object will be drawn in render order.

• var normalEnabled: Bool

  If true, normal mapping is enabled. This has a slight performance cost, especially on mobile GPUs.

• var normalScale: Double

  The strength of the normal map’s effect.

• var normalTexture: Texture2D?

  Texture used to specify the normal at a given pixel. The normalTexture only uses the red and green channels; the blue and alpha channels are ignored. The normal read from normalTexture is oriented around the surface normal provided by the Mesh.

• var ormTexture: Texture2D?

  The Occlusion/Roughness/Metallic texture to use. This is a more efficient replacement of aoTexture, roughnessTexture and metallicTexture in ORMMaterial3D. Ambient occlusion is stored in the red channel. Roughness map is stored in the green channel. Metallic map is stored in the blue channel. The alpha channel is ignored.

• var particlesAnimHFrames: Int32

  The number of horizontal frames in the particle sprite sheet. Only enabled when using .billboardParticles. See billboardMode.

• var particlesAnimLoop: Bool

  If true, particle animations are looped. Only enabled when using .billboardParticles. See billboardMode.

• var particlesAnimVFrames: Int32

  The number of vertical frames in the particle sprite sheet. Only enabled when using .billboardParticles. See billboardMode.

• var pointSize: Double

  The point size in pixels. See usePointSize.

• var proximityFadeDistance: Double

  Distance over which the fade effect takes place. The larger the distance the longer it takes for an object to fade.

• var proximityFadeEnabled: Bool

  If true, the proximity fade effect is enabled. The proximity fade effect fades out each pixel based on its distance to another object.

• var refractionEnabled: Bool

  If true, the refraction effect is enabled. Distorts transparency based on light from behind the object.

• var refractionScale: Double

  The strength of the refraction effect.

• var refractionTexture: Texture2D?

  Texture that controls the strength of the refraction per-pixel. Multiplied by refractionScale.

• var refractionTextureChannel: BaseMaterial3D.TextureChannel

  Specifies the channel of the refractionTexture in which the refraction information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored refraction in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.

• var rim: Double

  Sets the strength of the rim lighting effect.

• var rimEnabled: Bool

  If true, rim effect is enabled. Rim lighting increases the brightness at glancing angles on an object.

• var rimTexture: Texture2D?

  Texture used to set the strength of the rim lighting effect per-pixel. Multiplied by rim.

• var rimTint: Double

  The amount of to blend light and albedo color when rendering rim effect. If 0 the light color is used, while 1 means albedo color is used. An intermediate value generally works best.

• var roughness: Double

  Surface reflection. A value of 0 represents a perfect mirror while a value of 1 completely blurs the reflection. See also metallic.

• var roughnessTexture: Texture2D?

  Texture used to control the roughness per-pixel. Multiplied by roughness.

• var shadingMode: BaseMaterial3D.ShadingMode

  Sets whether the shading takes place, per-pixel, per-vertex or unshaded. Per-vertex lighting is faster, making it the best choice for mobile applications, however it looks considerably worse than per-pixel. Unshaded rendering is the fastest, but disables all interactions with lights.

• var shadowToOpacity: Bool

  If true, enables the “shadow to opacity” render mode where lighting modifies the alpha so shadowed areas are opaque and non-shadowed areas are transparent. Useful for overlaying shadows onto a camera feed in AR.

• var specularMode: BaseMaterial3D.SpecularMode

  The method for rendering the specular blob. See SpecularMode.

• var subsurfScatterEnabled: Bool

  If true, subsurface scattering is enabled. Emulates light that penetrates an object’s surface, is scattered, and then emerges. Subsurface scattering quality is controlled by ProjectSettings/rendering/environment/subsurfaceScattering/subsurfaceScatteringQuality.

• var subsurfScatterSkinMode: Bool

  If true, subsurface scattering will use a special mode optimized for the color and density of human skin, such as boosting the intensity of the red channel in subsurface scattering.

• var subsurfScatterStrength: Double

  The strength of the subsurface scattering effect. The depth of the effect is also controlled by ProjectSettings/rendering/environment/subsurfaceScattering/subsurfaceScatteringScale, which is set globally.

• var subsurfScatterTexture: Texture2D?

  Texture used to control the subsurface scattering strength. Stored in the red texture channel. Multiplied by subsurfScatterStrength.

• var subsurfScatterTransmittanceBoost: Double

  The intensity of the subsurface scattering transmittance effect.

• var subsurfScatterTransmittanceColor: Color

  The color to multiply the subsurface scattering transmittance effect with. Ignored if subsurfScatterSkinMode is true.

• var subsurfScatterTransmittanceDepth: Double

  The depth of the subsurface scattering transmittance effect.

• var subsurfScatterTransmittanceEnabled: Bool

  If true, enables subsurface scattering transmittance. Only effective if subsurfScatterEnabled is true. See also backlightEnabled.

  The texture to use for multiplying the intensity of the subsurface scattering transmitteance intensity. See also subsurfScatterTexture. Ignored if subsurfScatterSkinMode is true.

• var textureFilter: BaseMaterial3D.TextureFilter

  Filter flags for the texture. See TextureFilter for options.

• var textureRepeat: Bool

  Repeat flags for the texture. See TextureFilter for options.

• var transparency: BaseMaterial3D.Transparency

  The material’s transparency mode. Some transparency modes will disable shadow casting. Any transparency mode other than .disabled has a greater performance impact compared to opaque rendering. See also blendMode.

• var useParticleTrails: Bool

  If true, enables parts of the shader required for GPUParticles3D trails to function. This also requires using a mesh with appropriate skinning, such as RibbonTrailMesh or TubeTrailMesh. Enabling this feature outside of materials used in GPUParticles3D meshes will break material rendering.

• var usePointSize: Bool

  If true, render point size can be changed.

• var uv1Offset: Vector3

  How much to offset the UV coordinates. This amount will be added to UV in the vertex function. This can be used to offset a texture. The Z component is used when uv1Triplanar is enabled, but it is not used anywhere else.

• var uv1Scale: Vector3

  How much to scale the UV coordinates. This is multiplied by UV in the vertex function. The Z component is used when uv1Triplanar is enabled, but it is not used anywhere else.

• var uv1Triplanar: Bool

  If true, instead of using UV textures will use a triplanar texture lookup to determine how to apply textures. Triplanar uses the orientation of the object’s surface to blend between texture coordinates. It reads from the source texture 3 times, once for each axis and then blends between the results based on how closely the pixel aligns with each axis. This is often used for natural features to get a realistic blend of materials. Because triplanar texturing requires many more texture reads per-pixel it is much slower than normal UV texturing. Additionally, because it is blending the texture between the three axes, it is unsuitable when you are trying to achieve crisp texturing.

• var uv1TriplanarSharpness: Double

  A lower number blends the texture more softly while a higher number blends the texture more sharply.

• var uv1WorldTriplanar: Bool

  If true, triplanar mapping for UV is calculated in world space rather than object local space. See also uv1Triplanar.

• var uv2Offset: Vector3

  How much to offset the UV2 coordinates. This amount will be added to UV2 in the vertex function. This can be used to offset a texture. The Z component is used when uv2Triplanar is enabled, but it is not used anywhere else.

• var uv2Scale: Vector3

  How much to scale the UV2 coordinates. This is multiplied by UV2 in the vertex function. The Z component is used when uv2Triplanar is enabled, but it is not used anywhere else.

• var uv2Triplanar: Bool

  If true, instead of using UV2 textures will use a triplanar texture lookup to determine how to apply textures. Triplanar uses the orientation of the object’s surface to blend between texture coordinates. It reads from the source texture 3 times, once for each axis and then blends between the results based on how closely the pixel aligns with each axis. This is often used for natural features to get a realistic blend of materials. Because triplanar texturing requires many more texture reads per-pixel it is much slower than normal UV texturing. Additionally, because it is blending the texture between the three axes, it is unsuitable when you are trying to achieve crisp texturing.

• var uv2TriplanarSharpness: Double

  A lower number blends the texture more softly while a higher number blends the texture more sharply.

• var uv2WorldTriplanar: Bool

  If true, triplanar mapping for UV2 is calculated in world space rather than object local space. See also uv2Triplanar.

• var vertexColorIsSrgb: Bool

  If true, vertex colors are considered to be stored in sRGB color space and are converted to linear color space during rendering. If false, vertex colors are considered to be stored in linear color space and are rendered as-is. See also albedoTextureForceSrgb.

• var vertexColorUseAsAlbedo: Bool

  If true, the vertex color is used as albedo color.
