This provides a default material with a wide variety of rendering features and properties without the need to write shader code. See the tutorial below for details.
If [code]true[/code], enables the specified [enum Feature]. Many features that are available in [SpatialMaterial]s need to be enabled before use. This way the cost for using the feature is only incurred when specified. Features can also be enabled by setting the corresponding member to [code]true[/code].
If [code]true[/code], enables the specified flag. Flags are optional behavior that can be turned on and off. Only one flag can be enabled at a time with this function, the flag enumerators cannot be bit-masked together to enable or disable multiple flags at once. Flags can also be enabled by setting the corresponding member to [code]true[/code]. See [enum Flags] enumerator for options.
The strength of the anisotropy effect. This is multiplied by [member anisotropy_flowmap]'s alpha channel if a texture is defined there and the texture contains an alpha channel.
If [code]true[/code], 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.
[b]Note:[/b] Mesh tangents are needed for anisotropy to work. If the mesh does not contain tangents, the anisotropy effect will appear broken.
[b]Note:[/b] Material anisotropy should not to be confused with anisotropic texture filtering. Anisotropic texture filtering can be enabled by selecting a texture in the FileSystem dock, going to the Import dock, checking the [b]Anisotropic[/b] checkbox then clicking [b]Reimport[/b]. The anisotropic filtering level can be changed by adjusting [member ProjectSettings.rendering/quality/filters/anisotropic_filter_level].
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.
If present, the texture's alpha channel will be used to multiply the strength of the [member anisotropy] effect. Fully opaque pixels will keep the anisotropy effect's original strength while fully transparent pixels will disable the anisotropy effect entirely. The flowmap texture's blue channel is ignored.
Amount that ambient occlusion affects lighting from lights. If [code]0[/code], ambient occlusion only affects ambient light. If [code]1[/code], 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.
Specifies the channel of the [member ao_texture] 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.
If [member ProjectSettings.rendering/gles3/shaders/shader_compilation_mode] is [code]Synchronous[/code] (with or without cache), this determines how this material must behave in regards to asynchronous shader compilation.
[constant ASYNC_MODE_VISIBLE] is the default and the best for most cases.
If [code]true[/code], 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.
[b]Note:[/b] Clearcoat rendering is not visible if the material has [member flags_unshaded] set to [code]true[/code].
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.
If [code]true[/code], the shader will read depth texture at multiple points along the view ray to determine occlusion and parrallax. This can be very performance demanding, but results in more realistic looking depth mapping.
If [code]true[/code], depth mapping is enabled (also called "parallax mapping" or "height mapping"). See also [member normal_enabled].
[b]Note:[/b] Depth mapping is not supported if triplanar mapping is used on the same material. The value of [member depth_enabled] will be ignored if [member uv1_triplanar] is enabled.
If [code]true[/code], direction of the binormal is flipped before using in the depth effect. This may be necessary if you have encoded your binormals in a way that is conflicting with the depth effect.
If [code]true[/code], direction of the tangent is flipped before using in the depth effect. This may be necessary if you have encoded your tangents in a way that is conflicting with the depth effect.
Number of layers to use when using [member depth_deep_parallax] and the view direction is perpendicular to the surface of the object. A higher number will be more performance demanding while a lower number may not look as crisp.
Number of layers to use when using [member depth_deep_parallax] and the view direction is parallel to the surface of the object. A higher number will be more performance demanding while a lower number may not look as crisp.
If [code]true[/code], enables the detail overlay. Detail is a second texture that gets mixed over the surface of the object based on [member detail_mask]. This can be used to add variation to objects, or to blend between two different albedo/normal textures.
Texture that specifies the per-pixel normal of the detail overlay.
[b]Note:[/b] Godot expects the normal map to use X+, Y+, and Z+ coordinates. See [url=http://wiki.polycount.com/wiki/Normal_Map_Technical_Details#Common_Swizzle_Coordinates]this page[/url] for a comparison of normal map coordinates expected by popular engines.
Distance at which the object appears fully opaque.
[b]Note:[/b] If [code]distance_fade_max_distance[/code] is less than [code]distance_fade_min_distance[/code], the behavior will be reversed. The object will start to fade away at [code]distance_fade_max_distance[/code] and will fully disappear once it reaches [code]distance_fade_min_distance[/code].
Distance at which the object starts to become visible. If the object is less than this distance away, it will be invisible.
[b]Note:[/b] If [code]distance_fade_min_distance[/code] is greater than [code]distance_fade_max_distance[/code], the behavior will be reversed. The object will start to fade away at [code]distance_fade_max_distance[/code] and will fully disappear once it reaches [code]distance_fade_min_distance[/code].
If [code]true[/code], the body emits light. Emitting light makes the object appear brighter. The object can also cast light on other objects if a [GIProbe] or [BakedLightmap] is used and this object is used in baked lighting.
If [code]true[/code], the shader will compute extra operations to make sure the normal stays correct when using a non-uniform scale. Only enable if using non-uniform scaling.
If [code]true[/code], 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.
If [code]true[/code], lighting is calculated per vertex rather than per pixel. This may increase performance on low-end devices, especially for meshes with a lower polygon count. The downside is that shading becomes much less accurate, with visible linear interpolation between vertices that are joined together. This can be compensated by ensuring meshes have a sufficient level of subdivision (but not too much, to avoid reducing performance). Some material features are also not supported when vertex shading is enabled.
See also [member ProjectSettings.rendering/quality/shading/force_vertex_shading] which can globally enable vertex shading on all materials.
[b]Note:[/b] By default, vertex shading is enforced on mobile platforms by [member ProjectSettings.rendering/quality/shading/force_vertex_shading]'s [code]mobile[/code] override.
[b]Note:[/b] [member flags_vertex_lighting] has no effect if [member flags_unshaded] is [code]true[/code].
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 [code]0[/code] and [code]1[/code] should only be used for blending between metal and non-metal sections. To alter the amount of reflection use [member roughness].
Sets the size of the specular lobe. The specular lobe is the bright spot that is reflected from light sources.
[b]Note:[/b] Unlike [member metallic], this is not energy-conserving, so it should be left at [code]0.5[/code] in most cases. See also [member roughness].
Specifies the channel of the [member metallic_texture] 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.
Texture used to specify the normal at a given pixel. The [code]normal_texture[/code] only uses the red and green channels; the blue and alpha channels are ignored. The normal read from [code]normal_texture[/code] is oriented around the surface normal provided by the [Mesh].
[b]Note:[/b] The mesh must have both normals and tangents defined in its vertex data. Otherwise, the normal map won't render correctly and will only appear to darken the whole surface. If creating geometry with [SurfaceTool], you can use [method SurfaceTool.generate_normals] and [method SurfaceTool.generate_tangents] to automatically generate normals and tangents respectively.
[b]Note:[/b] Godot expects the normal map to use X+, Y+, and Z+ coordinates. See [url=http://wiki.polycount.com/wiki/Normal_Map_Technical_Details#Common_Swizzle_Coordinates]this page[/url] for a comparison of normal map coordinates expected by popular engines.
If [code]true[/code], the shader will keep the scale set for the mesh. Otherwise the scale is lost when billboarding. Only applies when [member params_billboard_mode] is [constant BILLBOARD_ENABLED].
Controls how the object faces the camera. See [enum BillboardMode].
[b]Note:[/b] Billboard mode is not suitable for VR because the left-right vector of the camera is not horizontal when the screen is attached to your head instead of on the table. See [url=https://github.com/godotengine/godot/issues/41567]GitHub issue #41567[/url] for details.
The number of horizontal frames in the particle sprite sheet. Only enabled when using [constant BILLBOARD_PARTICLES]. See [member params_billboard_mode].
The number of vertical frames in the particle sprite sheet. Only enabled when using [constant BILLBOARD_PARTICLES]. See [member params_billboard_mode].
If [code]true[/code], the refraction effect is enabled. Refraction distorts transparency based on light from behind the object. When using the GLES3 backend, the material's roughness value will affect the blurriness of the refraction. Higher roughness values will make the refraction look blurrier.
Specifies the channel of the [member refraction_texture] 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 metallic in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.
The amount of to blend light and albedo color when rendering rim effect. If [code]0[/code] the light color is used, while [code]1[/code] means albedo color is used. An intermediate value generally works best.
Surface reflection. A value of [code]0[/code] represents a perfect mirror while a value of [code]1[/code] completely blurs the reflection. See also [member metallic].
Specifies the channel of the [member ao_texture] 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.
How much to offset the [code]UV[/code] coordinates. This amount will be added to [code]UV[/code] in the vertex function. This can be used to offset a texture.
If [code]true[/code], instead of using [code]UV[/code] 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.
How much to offset the [code]UV2[/code] coordinates. This amount will be added to [code]UV2[/code] in the vertex function. This can be used to offset a texture.
If [code]true[/code], instead of using [code]UV2[/code] 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.

Additionally, because it is blending the texture between the three axes, it is unsuitable when you are trying to achieve crisp texturing.
Uses point size to alter the size of primitive points. Also changes the albedo texture lookup to use [code]POINT_COORD[/code] instead of [code]UV[/code].
Shader will keep the scale set for the mesh. Otherwise the scale is lost when billboarding. Only applies when [member params_billboard_mode] is [constant BILLBOARD_ENABLED].
Smoothly fades the object out based on each pixel's distance from the camera using a dither approach. Dithering discards pixels based on a set pattern to smoothly fade without enabling transparency. On certain hardware this can be faster than [constant DISTANCE_FADE_PIXEL_ALPHA].

The real conditioned shader needed on each situation will be sent for background compilation. In the meantime, a very complex shader that adapts to every situation will be used ("ubershader"). This ubershader is much slower to render, but will keep the game running without stalling to compile. Once shader compilation is done, the ubershader is replaced by the traditional optimized shader.
Anything with this material applied won't be rendered while this material's shader is being compiled.
This is useful for optimization, in cases where the visuals won't suffer from having certain non-essential elements missing during the short time their shaders are being compiled.
