# LightmapParameters > Configures how Unity bakes lighting and can be assigned to a LightingSettings instance or asset. ## Definition * **Type:** Class * **Namespace:** [UnityEditor](/engine/6000.5/script-reference/unityeditor.md) * **Assembly:** UnityEditor.CoreModule * **Inherits from:** [Object](/engine/6000.5/script-reference/unityengine/object.md) ```csharp public sealed class LightmapParameters : Object ``` ## Remarks Note that Unity's built-in Lightmap Parameters Assets are read-only. Additional Resources: [LightmapParameters.SetLightmapParametersForLightingSettings](/engine/6000.5/script-reference/unityeditor/lightmapparameters/setlightmapparametersforlightingsettings.md). ## Properties | Property | Description | | ---------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [antiAliasingSamples](/engine/6000.5/script-reference/unityeditor/lightmapparameters/antialiasingsamples-1.md) | The kernel width the lightmapper uses when sampling a lightmap texel. | | [AOAntiAliasingSamples](/engine/6000.5/script-reference/unityeditor/lightmapparameters/aoantialiasingsamples.md) | The maximum number of times to supersample a texel to reduce aliasing in AO. | | [AOQuality](/engine/6000.5/script-reference/unityeditor/lightmapparameters/aoquality.md) | The number of rays to cast for computing ambient occlusion. | | [backFaceTolerance](/engine/6000.5/script-reference/unityeditor/lightmapparameters/backfacetolerance.md) | The percentage of rays shot from a ray origin that must hit front faces to be considered usable. | | [bakedLightmapTag](/engine/6000.5/script-reference/unityeditor/lightmapparameters/bakedlightmaptag.md) | BakedLightmapTag is an integer that affects the assignment to baked lightmaps. Objects with different values for bakedLightmapTag are guaranteed to not be assigned to the same lightmap even if the other baking parameters are the same. | | [blurRadius](/engine/6000.5/script-reference/unityeditor/lightmapparameters/blurradius.md) | The radius (in texels) of the post-processing filter that blurs baked direct lighting. | | [clusterResolution](/engine/6000.5/script-reference/unityeditor/lightmapparameters/clusterresolution.md) | Controls the resolution at which Enlighten Realtime Global Illumination stores and can transfer input light. | | [directLightQuality](/engine/6000.5/script-reference/unityeditor/lightmapparameters/directlightquality.md) | The number of rays used for lights with an area. Allows for accurate soft shadowing. | | [irradianceBudget](/engine/6000.5/script-reference/unityeditor/lightmapparameters/irradiancebudget.md) | The amount of data used for Enlighten Realtime Global Illumination texels. Specifies how detailed view of the Scene a texel has. Small values mean more averaged out lighting. | | [irradianceQuality](/engine/6000.5/script-reference/unityeditor/lightmapparameters/irradiancequality.md) | The number of rays to cast for computing irradiance form factors. | | [isTransparent](/engine/6000.5/script-reference/unityeditor/lightmapparameters/istransparent.md) | If enabled, the object appears transparent during GlobalIllumination lighting calculations. | | [limitLightmapCount](/engine/6000.5/script-reference/unityeditor/lightmapparameters/limitlightmapcount.md) | If enabled, objects sharing the same lightmap parameters will be packed into [LightmapParameters.maxLightmapCount](/engine/6000.5/script-reference/unityeditor/lightmapparameters/maxlightmapcount.md) lightmaps. | | [maxLightmapCount](/engine/6000.5/script-reference/unityeditor/lightmapparameters/maxlightmapcount.md) | The maximum number of lightmaps created for objects sharing the same lightmap parameters. This property is ignored if [LightmapParameters.limitLightmapCount](/engine/6000.5/script-reference/unityeditor/lightmapparameters/limitlightmapcount.md) is false. | | [modellingTolerance](/engine/6000.5/script-reference/unityeditor/lightmapparameters/modellingtolerance.md) | Maximum size of gaps that can be ignored for GI (multiplier on pixel size). | | [pushoff](/engine/6000.5/script-reference/unityeditor/lightmapparameters/pushoff.md) | The distance to offset the ray origin from the geometry when performing ray tracing, in modelling units. Unity applies the offset to all baked lighting: direct lighting, indirect lighting, environment lighting and ambient occlusion. | | [resolution](/engine/6000.5/script-reference/unityeditor/lightmapparameters/resolution.md) | The texel resolution per meter used for real-time lightmaps. This value is multiplied by [LightingSettings.indirectResolution](/engine/6000.5/script-reference/unityengine/lightingsettings/indirectresolution.md). | | [stitchEdges](/engine/6000.5/script-reference/unityeditor/lightmapparameters/stitchedges.md) | Whether pairs of edges should be stitched together. | | [systemTag](/engine/6000.5/script-reference/unityeditor/lightmapparameters/systemtag.md) | System tag is an integer identifier. It lets you force an object into a different Enlighten Realtime Global Illumination system even though all the other parameters are the same. | ## Methods | Method | Description | | ---------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------- | | [AssignToLightingSettings](/engine/6000.5/script-reference/unityeditor/lightmapparameters/assigntolightingsettings.md) | Assignes itself to a
