# FSR2TextureTable > The set of texture slots available for the FSR2Context and FSRUpscalerContext. ## Definition * **Type:** Struct * **Namespace:** [UnityEngine.AMD](/engine/6000.7/script-reference/unityengine/amd.md) * **Assembly:** UnityEngine.AMDModule ```csharp public struct FSR2TextureTable ``` ## Remarks Use this struct to specify input and output textures for FSR2, FSR3, and FSR4 upscaling. **Note:** You must create output color texture `colorOutput` with `enableRandomWrite` parameter set to `true` when initializing the RTHandle of the texture. This is due to FSR passes requiring access to the resources in a compute shader. Refer to the Input resources section in AMD's documentation for more details: * [FSR2 - Input resources](https://gpuopen.com/manuals/fidelityfx_sdk/techniques/super-resolution-temporal/#input-resources) * [FSR3 - Input resources](https://gpuopen.com/manuals/fsr_sdk/techniques/super-resolution-upscaler/#input-resources) * [FSR4 - Input resources](https://gpuopen.com/manuals/fsr_sdk/techniques/super-resolution-ml/#input-resources) Additional Resources: [AMDUnityPlugin](/engine/6000.7/script-reference/unityengine/amd/amdunityplugin.md), [GraphicsDevice](/engine/6000.7/script-reference/unityengine/amd/graphicsdevice.md), [FSR2Context](/engine/6000.7/script-reference/unityengine/amd/fsr2context.md), [FSRUpscalerContext](/engine/6000.7/script-reference/unityengine/amd/fsrupscalercontext.md), [FSR2CommandInitializationData](/engine/6000.7/script-reference/unityengine/amd/fsr2commandinitializationdata.md), [FSRUpscalerCommandInitializationData](/engine/6000.7/script-reference/unityengine/amd/fsrupscalercommandinitializationdata.md), [FSR2CommandExecutionData](/engine/6000.7/script-reference/unityengine/amd/fsr2commandexecutiondata.md) ## Examples ```csharp using UnityEngine; using UnityEngine.Rendering; using UnityEngine.Rendering.HighDefinition; using UnityEngine.Experimental.Rendering; using UnityEngine.AMD; // Example HDRP custom pass public class CustomFSRPass : CustomPass { void InitializeAMDDevice() { // device initialization code } bool HasOutputResolutionChanged(CustomPassContext ctx) { // detect resolution change } bool HasInputResolutionChanged(CustomPassContext ctx) { // detect resolution change } protected override void Setup(ScriptableRenderContext renderContext, CommandBuffer cmd) { if (amdDevice == null) { InitializeAMDDevice(); } float scalingRatio = fsr2Context == null ? 1.0f : amdDevice.GetUpscaleRatioFromQualityMode(m_Quality); fsr2OutputColorBuffer = RTHandles.Alloc( new Vector2(scalingRatio, scalingRatio), slices: 1, dimension: TextureDimension.Tex2D, colorFormat: GraphicsFormat.R16G16B16A16_SFloat, name: "fsr2OutputColorBuffer", enableRandomWrite: true ); } protected override void Execute(CustomPassContext ctx) { bool initializeFsr2Context = fsr2Context == null || HasInputResolutionChanged(ctx) || HasOutputResolutionChanged(ctx); if (initializeFsr2Context) { // fsr2Context initialization code } fsr2Context.executeData.enableSharpening = m_EnableSharpening ? 1 : 0; // populate rest of the fsr2Context.executeData FSR2TextureTable fsr2TextureTable = new FSR2TextureTable() { // Mandatory inputs colorInput = ctx.cameraColorBuffer, colorOutput = fsr2OutputColorBuffer, depth = ctx.cameraDepthBuffer, motionVectors = ctx.cameraMotionVectorsBuffer, // Optional inputs transparencyMask = null, exposureTexture = null, reactiveMask = null, biasColorMask = null }; amdDevice.ExecuteFSR2(ctx.cmd, fsr2Context, fsr2TextureTable); } protected override void Cleanup() { // cleanup code } private GraphicsDevice amdDevice = null; private FSR2Context fsr2Context = null; private RTHandle fsr2OutputColorBuffer; [SerializeField] public float m_Sharpness = 0.92f; [SerializeField] public bool m_EnableSharpening = true; [SerializeField] public FSR2Quality m_Quality = FSR2Quality.Quality; FSR2Quality m_QualityBefore = FSR2Quality.Quality; Vector2Int m_InputTextureSize = new Vector2Int(0,0); } ``` ## Properties | Property | Description | | -------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [biasColorMask](/engine/6000.7/script-reference/unityengine/amd/fsr2texturetable/biascolormask.md) | This is obsolete. Use transparencyMask instead. If both are specified, then transparencyMask is used and this is ignored. | | [colorInput](/engine/6000.7/script-reference/unityengine/amd/fsr2texturetable/colorinput.md) | The input color texture to upsample for [FSR2Context](/engine/6000.7/script-reference/unityengine/amd/fsr2context.md) or [FSRUpscalerContext](/engine/6000.7/script-reference/unityengine/amd/fsrupscalercontext.md). This texture is mandatory and you must set it to a non-null value. | | [colorOutput](/engine/6000.7/script-reference/unityengine/amd/fsr2texturetable/coloroutput.md) | The output color texture. This texture is mandatory and you must set it to a non-null value. | | [depth](/engine/6000.7/script-reference/unityengine/amd/fsr2texturetable/depth.md) | The input depth texture. This must be the same size as the input color texture. This texture is mandatory and you must set it to a non-null value. | | [exposureTexture](/engine/6000.7/script-reference/unityengine/amd/fsr2texturetable/exposuretexture.md) | A 1x1 texture with pre-exposure values. See [AMD's documentation](https://gpuopen.com/manuals/fsr_sdk/techniques/super-resolution-upscaler/#exposure) for details. If you do not use pre-exposure, do not set this texture. Also if there's no particular reason then it's recommended to enable auto exposure via FfxFsr2InitializationFlags or FfxApiCreateContextUpscaleFlags instead of using this texture. This texture is optional. | | [motionVectors](/engine/6000.7/script-reference/unityengine/amd/fsr2texturetable/motionvectors.md) | The motion vectors texture. Depending on the [FfxFsr2InitializationFlags](/engine/6000.7/script-reference/unityengine/amd/ffxfsr2initializationflags.md) specified in [\_initData](/engine/6000.7/script-reference/unityengine/amd/fsr2context/initdata.md) or [FfxApiCreateContextUpscaleFlags](/engine/6000.7/script-reference/unityengine/amd/ffxapicreatecontextupscaleflags.md) specified in [\_initData](/engine/6000.7/script-reference/unityengine/amd/fsrupscalercontext/initdata.md), this texture can have the input resolution or output resolution. This texture is mandatory and you must set it to a non-null value. | | [reactiveMask](/engine/6000.7/script-reference/unityengine/amd/fsr2texturetable/reactivemask.md) | A texture of format R8\_UNORM and same size as colorInput that adjusts the temporal accumulation balance. See [AMD's documentation](https://gpuopen.com/manuals/fsr_sdk/techniques/super-resolution-upscaler/#reactive-mask) for details. This texture is optional in FSR2, FSR3 and ignored in FSR4. | | [transparencyMask](/engine/6000.7/script-reference/unityengine/amd/fsr2texturetable/transparencymask.md) | A texture of format R8\_UNORM and same size as colorInput that adjusts the pixel history protection mechanisms. See [AMD's documentation](https://gpuopen.com/manuals/fsr_sdk/techniques/super-resolution-upscaler/#transparency-and-composition-mask) for details. This texture is optional in FSR2, FSR3 and ignored in FSR4. |
