The strength of the anisotropy effect.

  • bool anisotropy_enabled
Default false
Setter set_feature(value)
Getter get_feature()

If true, anisotropy is enabled. Changes the shape of the specular blob and aligns it to tangent space. Mesh tangents are needed for this to work. If the mesh does not contain tangents the anisotropy effect will appear broken.

Setter set_texture(value)
Getter get_texture()

Texture that offsets the tangent map for anisotropy calculations.

Default false
Setter set_feature(value)
Getter get_feature()

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

Setter set_ao_light_affect(value)
Getter get_ao_light_affect()

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.

Setter set_flag(value)
Getter get_flag()

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

Setter set_texture(value)
Getter get_texture()

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

Setter set_ao_texture_channel(value)
Getter get_ao_texture_channel()

Specifies the channel of the 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.

  • bool billboard_keep_scale
Default false
Setter set_flag(value)
Getter get_flag()

If true, the shader will keep the scale set for the mesh. Otherwise the scale is lost when billboarding. Only applies when billboard_mode is BILLBOARD_ENABLED.

  • bool clearcoat_enabled

Getter get_heightmap_scale()
Setter set_texture(value)
Getter get_texture()
Default 0.0
Setter set_metallic(value)
Getter get_metallic()

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.

Default 0
Setter set_metallic_texture_channel(value)

  • bool no_depth_test
Default false

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

  • bool normal_enabled
Default false
Setter set_feature(value)
Getter get_feature()

Setter set_normal_scale(value)
Getter get_normal_scale()

The strength of the normal map’s effect.

Setter set_refraction_texture_channel(value)
Getter get_refraction_texture_channel()

Specifies the channel of the 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.

Default Vector3( 1, 1, 1 )
Setter set_uv1_scale(value)
Getter get_uv1_scale()

How much to scale the UV coordinates. This is multiplied by UV in the vertex function.

  • bool uv1_triplanar
Default false
Setter set_flag(value)
Getter get_flag()

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.

  • float uv1_triplanar_sharpness
Default 1.0
Setter set_uv1_triplanar_blend_sharpness(value)
Getter get_uv1_triplanar_blend_sharpness()

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

  • bool uv1_world_triplanar
Default false
Setter set_flag(value)
Getter get_flag()

If true, triplanar mapping for UV is calculated in world space rather than object local space. See also uv1_triplanar.

Default Vector3( 0, 0, 0 )
Setter set_uv2_offset(value)
Getter get_uv2_offset()

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.

Default Vector3( 1, 1, 1 )
Setter set_uv2_scale(value)
Getter get_uv2_scale()

How much to scale the UV2 coordinates. This is multiplied by UV2 in the vertex function.

  • bool vertex_color_is_srgb
Default false
Setter set_flag(value)
Getter get_flag()

If true, the model’s vertex colors are processed as sRGB mode.

  • bool vertex_color_use_as_albedo
Default false
Setter set_flag(value)
Getter get_flag()

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

Method Descriptions

Returns true, if the specified Feature is enabled.

Returns true, if the specified flag is enabled. See Flags enumerator for options.

Returns the Texture associated with the specified TextureParam.

If true, enables the specified Feature. Many features that are available in BaseMaterial3Ds 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 true.

If true, 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 true. See Flags enumerator for options.

Sets the texture for the slot specified by param. See TextureParam for available slots.
