      | alphaTestRef | Gets and sets a default alpha test reference values. | 
      | animateCrossFading | Indicates if the cross-fade LOD transition, applied to the last mesh LOD and the billboard, should be animated. | 
      | bestWindQuality | Returns the best-possible wind quality on this asset (configured in SpeedTree modeler). | 
      | billboardTransitionCrossFadeWidth | Proportion of the last 3D mesh LOD region width which is used for cross-fading to billboard tree. | 
      | castShadows | Gets and sets an array of booleans to enable shadow casting for each LOD. | 
      | castShadowsByDefault | Gets and sets a boolean to toggle whether the imported SpeedTree casts shadows. | 
      | defaultBillboardShader | Returns the default SpeedTree billboard shader for the active render pipeline, or null if the asset is a SpeedTree v8 asset. | 
      | defaultShader | Returns the default SpeedTree shader for the active render pipeline (either v7 or v8 according to the asset version). | 
      | enableBump | Gets and sets an array of booleans to enable normal mapping for each LOD. | 
      | enableBumpByDefault | Gets and sets a boolean to enable normal mapping on the imported SpeedTree model. | 
      | enableHue | Gets and sets an array of booleans to enable hue variation effect for each LOD. | 
      | enableHueByDefault | Gets and sets a boolean to enable hue variation effect on the imported SpeedTree model. | 
      | enableSettingOverride | Gets and sets an array of booleans to customize importer settings for a specific LOD. | 
      | enableSmoothLODTransition | Enables smooth LOD transitions. | 
      | enableSubsurface | Gets and sets an array of booleans to enable the subsurface scattering effect for each LOD (affects only SpeedTree v8 assets). | 
      | enableSubsurfaceByDefault | Gets and sets a boolean to enable the subsurface scattering effect for the SpeedTree asset (affects only SpeedTree v8 assets). | 
      | fadeOutWidth | Proportion of the billboard LOD region width which is used for fading out the billboard. | 
      | generateColliders | Gets and sets the boolean to toggle collider object generation during import. | 
      | generateRigidbody | Gets and sets the boolean to toggle Rigidbody generation during import. | 
      | hasBillboard | Tells if there is a billboard LOD. | 
      | hasImported | Tells if the SPM file has been previously imported. | 
      | hueVariation | Gets and sets a default hue variation color and amount (in alpha). | 
      | isV8 | Returns true if the asset is a SpeedTree v8 asset. | 
      | LODHeights | Gets and sets an array of floats of each LOD's screen height value. | 
      | mainColor | Gets and sets a default main color. | 
      | materialFolderPath | Returns the folder path where generated materials will be placed in. | 
      | materialLocation | Material import location options. | 
      | receiveShadows | Gets and sets an array of booleans to enable shadow receiving for each LOD. | 
      | receiveShadowsByDefault | Gets and sets a boolean to enable whether the SpeedTree asset receives shadows from other objects in your scene. | 
      | scaleFactor | How much to scale the tree model compared to what is in the imported SpeedTree model file. | 
      | selectedWindQuality | Gets and sets an integer corresponding to the SpeedTreeWind enum values. The value is clamped by SpeedTreeImporter.bestWindQuality internally. | 
      | useLightProbes | Gets and sets an array of booleans to enable Light Probe lighting for each LOD. | 
      | useLightProbesByDefault | Gets and sets a boolean to enable light probe lighting for the imported SpeedTree model. | 
      | windQualities | Gets and sets an array of integers of the wind qualities on each LOD. Values will be clamped by SpeedTreeImporter.bestWindQuality internally. |
