# Shader Import Settings window reference > View and edit properties and settings for a prebuilt shader or a custom shader. View and edit properties and settings for a [shader](/engine/6000.0/manual/materials-and-shaders.md). ## ShaderLab shader properties The following properties are available only for [ShaderLab shaders](/engine/6000.0/manual/materials-and-shaders/shaders/writing-custom/shader-writing/sl.md). | **Property** | **Description** | | ---------------------- | --------------------------------------------------------------------------------------------------------------------------------------------- | | **Default Maps** | Displays the textures that appear as material properties. | | **NonModifiable Maps** | Displays the textures that have the `[NonModifiableTextureData]` attribute in the shader. These textures don't appear as material properties. | ## Shader graph properties The following properties are available only for [shader graphs](/engine/6000.0/manual/materials-and-shaders/shaders/writing-custom/shader-graph.md). | **Property** | **Description** | | ------------------------- | ---------------------------------------------------------------------------------- | | **Open Shader Editor** | Opens the **Shader Graph** window so you can edit the shader graph. | | **View Generated Shader** | Opens your text editor with the ShaderLab shader code that Shader Graph generates. | | **Copy Shader** | Copies the ShaderLab shader code that Shader Graph generates to the clipboard. | ## Imported object | **Property** | **Description** | | -------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Surface Shader** | Opens your text editor with the shader Unity generates, if the shader is a [surface shader](/engine/6000.0/manual/materials-and-shaders/shaders/writing-shaders-birp/writing-surface.md). | | **Fixed Function** | Opens your text editor with the shader Unity generates, if the shader is a fixed function shader. | | **Preprocess only** | Sets **Compile and show code** to generate only the preprocessed code, instead of the final code. For more information, refer to [Shader compilation](/engine/6000.0/manual/materials-and-shaders/shaders/shader-troubleshooting/shader-reducing/shader-compilation.md). | | **Strip #line directives** | Removes `#line` statements that display how the preprocessed code maps to the original ShaderLab and HLSL code. This property is available only if you enable **Preprocess only**. | | **Compiled code** | Select **Compile and show code** to open your text editor with the shader code Unity compiles. Use the dropdown to select which graphics APIs and platforms Unity compiles the code for. For more information, refer to [Compiled code dropdown](#compiled-code-dropdown).This property is only available for code shaders. For shader graphs, select **View Generated Shader**. | | **Cast shadows** | Displays whether geometry casts shadows when it uses this shader. | | **Render queue** | Displays which render queue Unity uses for geometry that uses this shader. For more information, refer to [Set the render pipeline and render order for a shader](/engine/6000.0/manual/materials-and-shaders/shaders/writing-custom/shader-writing/writing-shader-tags/introduction.md). | | **LOD** | Displays the shader LOD value of the shader, which Unity uses to prioritize shaders. For more information, refer to [Optimize shaders](/engine/6000.0/manual/materials-and-shaders/shaders/sl-shader-performance.md). | | **Ignore projector** | Displays whether geometry that uses this shader receives effects from projector components. | | **Disable batching** | Displays whether the shader prevents Unity from applying dynamic batching to geometry that uses the shader. For more information, refer to [Batch meshes at runtime](/engine/6000.0/manual/analysis/graphics-performance-profiling/reduce-draw-calls/draw-call-batching/static-batching-enable.md). | | **Keywords** | Displays the **Overridable** and **Not Overridable** keywords the shader defines. For more information, refer to [shader keywords](/engine/6000.0/manual/materials-and-shaders/shaders/writing-custom/shader-writing/sl-multiple-program-variants/shader-keywords.md). | | **SRP Batcher** | Displays whether the shader is compatible with the [Scriptable Render Pipeline (SRP) Batcher](/engine/6000.0/manual/analysis/graphics-performance-profiling/in-urp/reduce-draw-calls-urp/srpbatcher.md). | | **Properties** | Displays the properties in the `Properties` block of the shader code. For more information, refer to [Properties block reference in ShaderLab](/engine/6000.0/manual/materials-and-shaders/shaders/reference/sl-reference/sl-shader-object/sl-properties.md). | ### Compiled code dropdown For more information, refer to [Shader compilation](/engine/6000.0/manual/materials-and-shaders/shaders/shader-troubleshooting/shader-reducing/shader-compilation.md). | **Property** | **Description** | | -------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Current graphics device** | Compiles the shader code for the graphics device on your current machine. | | **Current build platform** | Compiles the shader code for the current build platform. For more information, refer to [Build profiles](/engine/6000.0/manual/building-and-publishing/build-settings.md) | | **All platforms** | Compiles the shader code for all platforms and graphics APIs. | | **Custom** | Compiles the shader code for the graphics APIs you select. The options are:**D3D**: Compiles shader code into DirectX Bytecode (DXBC) for DirectX 11 or DirectX 12.**GLES3x**: Compiles shader code into OpenGL Shading Language (GLSL).**Metal**: Compiles shader code into Metal Shading Language (MSL).**OpenGLCore**: Compiles shader code into OpenGL Shading Language (GLSL).**Vulkan**: Compiles shader code into SPIR-V.**WebGPU**: Compiles shader code into WebGPU Shading Language (WGSL). | | **Skip unused shader\_features** | Strips shader variants that materials don't use. For more information, refer to [Changing how shaders work via branching and keywords](/engine/6000.0/manual/materials-and-shaders/shaders/writing-custom/shader-writing/sl-multiple-program-variants.md). | The bottom of the **Compiled code** dropdown displays the number of shader variants Unity compiles. Select **Show** to open your text editor with a list of the shader variants. ## Additional resources * [Introduction to shaders](/engine/6000.0/manual/materials-and-shaders/built-in/shader-introduction.md) * [Assets and media](/engine/6000.0/manual/assets-and-media.md)
