onUpdateShader?
UpdateShaderCallback | undefined
A custom function that will be called after all shader generator properties are collected and before shader code is generated. This function will receive an object with shader generator settings (based on current material and scene properties), that you can change and then return. Returned value will be used instead. This is mostly useful when rendering the same set of objects, but with different shader variations based on the same material. For example, you may wish to render a depth or normal pass using textures assigned to the material, a reflection pass with simpler shaders and so on. These properties are split into two sections, generic standard material options and lit options. Properties of the standard material options are StandardMaterialOptions and the options for the lit options are LitShaderOptions.

Quality depends on the number of MSAA samples of the current render target. It can nicely soften edges of otherwise sharp alpha cutouts, but isn't recommended for large area semi-transparent surfaces. Note, that you don't need to enable blending to make alpha to coverage work. It will work without it, just like alphaTest. This requires a multi-sampled render target, and is silently ignored when rendering to a single-sampled one. On WebGPU it additionally requires the first color attachment of the render target to use a blendable format with an alpha channel, and is silently ignored otherwise - note that PIXELFORMAT_111110F, the default HDR format used by CameraFrame, has no alpha channel.

cull?
number
Controls how triangles are culled based on their face direction with respect to the viewpoint.

-
flatShading?
boolean
Enables or disables flat shading. When enabled, the surface is shaded using the geometric normal of the triangle the fragment belongs to, instead of the normal interpolated from the vertex normals, giving the mesh a faceted look. This works on skinned and morphed geometry as well. The geometric normal is oriented to match the winding of the triangle, as configured by Material#frontFace , and so it agrees with correctly authored vertex normals. Flat shading therefore only changes the faceting - Material#cull , Material#frontFace and StandardMaterial#twoSidedLighting all behave the same as they do for smooth shading. StandardMaterial and LitMaterial implement this automatically. For a ShaderMaterial, this adds a `FLAT_SHADING` define to the shader, which the supplied shader code needs to handle. The `flatNormalPS` chunk provides the `getFlatNormal` function used by the engine internally, and can be used for this: ```javascript #include "flatNormalPS" ... #ifdef FLAT_SHADING vec3 normal = getFlatNormal(worldPos); #else vec3 normal = normalize(interpolatedNormal); #endif ``` As with other material properties, call Material#update after changing this. Defaults to false. Gets whether flat shading is enabled.
-

string
Sets the version of the shader chunks.

When providing custom shader chunks, set this to the latest supported version. If a future engine release no longer supports the specified version, a warning will be issued. In that case, update your shader chunks to match the new format and set this to the latest version accordingly. Returns the version of the shader chunks.

onUpdateShader
UpdateShaderCallback | undefined
A custom function that will be called after all shader generator properties are collected and before shader code is generated. This function will receive an object with shader generator settings (based on current material and scene properties), that you can change and then return. Returned value will be used instead. This is mostly useful when rendering the same set of objects, but with different shader variations based on the same material. For example, you may wish to render a depth or normal pass using textures assigned to the material, a reflection pass with simpler shaders and so on. These properties are split into two sections, generic standard material options and lit options. Properties of the standard material options are StandardMaterialOptions and the options for the lit options are LitShaderOptions.

number
The alpha test reference value to control which fragments are written to the currently active render target based on alpha value. All fragments with an alpha value of less than the alphaTest reference value will be discarded. alphaTest defaults to 0 (all fragments pass).
-
alphaToCoverage
boolean
Enables or disables alpha to coverage. When enabled, and if hardware anti-aliasing is on, limited order-independent transparency can be achieved. Quality depends on the number of MSAA samples of the current render target. It can nicely soften edges of otherwise sharp alpha cutouts, but isn't recommended for large area semi-transparent surfaces. Note, that you don't need to enable blending to make alpha to coverage work. It will work without it, just like alphaTest. This requires a multi-sampled render target, and is silently ignored when rendering to a single-sampled one. On WebGPU it additionally requires the first color attachment of the render target to use a blendable format with an alpha channel, and is silently ignored otherwise - note that PIXELFORMAT_111110F, the default HDR format used by CameraFrame, has no alpha channel.
-
_sceneTexturesWrite
any
Explicit setting of sceneTexturesWrite, or undefined to derive it from transparency.
-
cull
number
Controls how triangles are culled based on their face direction with respect to the viewpoint. Can be: - CULLFACE_NONE: Do not cull triangles based on face direction. - CULLFACE_BACK: Cull the back faces of triangles (do not render triangles facing away from the view point). - CULLFACE_FRONT: Cull the front faces of triangles (do not render triangles facing towards the view point). Defaults to CULLFACE_BACK.
-
frontFace

Stencil parameters for back faces (default is null).
-
_shaderChunks
any
-

-
_dirtyShader
boolean
-
flatShading
boolean
Enables or disables flat shading. When enabled, the surface is shaded using the geometric normal of the triangle the fragment belongs to, instead of the normal interpolated from the vertex normals, giving the mesh a faceted look. This works on skinned and morphed geometry as well. The geometric normal is oriented to match the winding of the triangle, as configured by Material#frontFace , and so it agrees with correctly authored vertex normals. Flat shading therefore only changes the faceting - Material#cull , Material#frontFace and StandardMaterial#twoSidedLighting all behave the same as they do for smooth shading. StandardMaterial and LitMaterial implement this automatically. For a ShaderMaterial, this adds a `FLAT_SHADING` define to the shader, which the supplied shader code needs to handle. The `flatNormalPS` chunk provides the `getFlatNormal` function used by the engine internally, and can be used for this: ```javascript #include "flatNormalPS" ... #ifdef FLAT_SHADING vec3 normal = getFlatNormal(worldPos); #else vec3 normal = normalize(interpolatedNormal); #endif ``` As with other material properties, call Material#update after changing this. Defaults to false. Gets whether flat shading is enabled.
-
getShaderChunks
(shaderLanguage?: string | undefined) => ShaderChunkMap
Returns an object containing shader chunks for a specific shader language for the material. These chunks define custom GLSL or WGSL code used to construct the final shader for the material. The chunks can be also be included in shaders using the `#include "ChunkName"` directive. On the WebGL platform: - If GLSL chunks are provided, they are used directly. On the WebGPU platform: - If WGSL chunks are provided, they are used directly. - If only GLSL chunks are provided, a GLSL shader is generated and then transpiled to WGSL, which is less efficient. To ensure faster shader compilation, it is recommended to provide shader chunks for all supported platforms. A simple example on how to override a shader chunk providing emissive color for both GLSL and WGSL to simply return a red color: ```javascript material.getShaderChunks(SHADERLANGUAGE_GLSL).set('emissivePS', ` void getEmission() { dEmission = vec3(1.0, 0.0, 1.0); } `); material.getShaderChunks(SHADERLANGUAGE_WGSL).set('emissivePS', ` fn getEmission() { dEmission = vec3f(1.0, 0.0, 1.0); } `); // call update to apply the changes material.update(); ```
-
shaderChunksVersion
string
Sets the version of the shader chunks. This should be a string containing the current engine major and minor version (e.g., '2.8' for engine v2.8.1) and ensures compatibility with the current engine version. When providing custom shader chunks, set this to the latest supported version. If a future engine release no longer supports the specified version, a warning will be issued. In that case, update your shader chunks to match the new format and set this to the latest version accordingly. Returns the version of the shader chunks.
-
depthBias
number
Sets the offset for the output depth buffer value. Useful for decals to prevent z-fighting. Typically a small negative value (-0.1) is used to render the mesh slightly closer to the camera. Gets the offset for the output depth buffer value.

blendState
Readonly<BlendState>
Sets the blend state for this material. Controls how fragment shader outputs are blended when being written to the currently active render target.

-
blendType
number
Sets the blend mode for this material. Controls how fragment shader outputs are blended when being written to the currently active render target. Can be: - BLEND_SUBTRACTIVE: Subtract the color of the source fragment from the destination fragment and write the result to the frame buffer. - BLEND_ADDITIVE: Add the color of the source fragment to the destination fragment and write the result to the frame buffer. - BLEND_NORMAL: Enable simple translucency for materials such as glass. This is equivalent to enabling a source blend mode of BLENDMODE_SRC_ALPHA and a destination blend mode of BLENDMODE_ONE_MINUS_SRC_ALPHA. - BLEND_NONE: Disable blending. - BLEND_PREMULTIPLIED: Similar to BLEND_NORMAL expect the source fragment is assumed to have already been multiplied by the source alpha value. - BLEND_MULTIPLICATIVE: Multiply the color of the source fragment by the color of the destination fragment and write the result to the frame buffer. - BLEND_ADDITIVEALPHA: Same as BLEND_ADDITIVE except the source RGB is multiplied by the source alpha. - BLEND_MULTIPLICATIVE2X: Multiplies colors and doubles the result. - BLEND_SCREEN: Softer version of additive. - BLEND_MIN: Minimum color. - BLEND_MAX: Maximum color.

-
update
() => void
Applies any changes made to the material's properties. This method should be called after modifying material properties to ensure the changes take effect. The method will clear cached shader variants and trigger recompilation if: - Modified material properties require a different shader variant (e.g., enabling/disabling textures or other properties that affect shader generation) - Material-specific shader chunks (from getShaderChunks) have been modified - Global shader chunks (from ShaderChunks.get) have been modified - Material defines have been changed Note: Shaders are not compiled immediately. Instead, existing shader variants are cleared and new variants will be compiled on-demand as they are needed for different render passes (e.g., forward, shadow, pick). When global shader chunks are modified, `update()` must be called on each material that should reflect those changes.
