Make sure to add the boxes to the scene from [Runtime.getTileBoxes()](./three-loader-3dtiles.runtime.gettileboxes.md) - Default: false | | [dracoDecoderPath?](./three-loader-3dtiles.loaderoptions.dracodecoderpath.md) | string | (Optional) A path to that contains the draco library. e.g: https://unpkg.com/three@0.129.0/examples/js/libs/draco - Default: undefined | | [geoTransform?](./three-loader-3dtiles.loaderoptions.geotransform.md) | GeoTransform | (Optional) How to handle geo transformations: Reset any geo location and place the model at (0,0,0), Apply Mercator projection (for use with ccommon 2D mapping applications, or convert WGS84 long/lat to 3D cartesian coordinates)- Default: Reset | | [material?](./three-loader-3dtiles.loaderoptions.material.md) | Material | (Optional) Apply a custom material, supports both b3dm (mesh) tiles and Point Cloud tiles - Default: undefined \* | | [maxConcurrency?](./three-loader-3dtiles.loaderoptions.maxconcurrency.md) | number | (Optional) Maximum worker thread concurrency when processing DRACO-compressed tiles - Default: 1 worker. | | [maximumMemoryUsage?](./three-loader-3dtiles.loaderoptions.maximummemoryusage.md) | number | (Optional) Maximum GPU memory (MB) to use for displaying tiles. May go over the limit if tiles within the camera viewport exceed that ammount - Default: 32. | | [maximumScreenSpaceError?](./three-loader-3dtiles.loaderoptions.maximumscreenspaceerror.md) | number | (Optional) determines the distance from tiles in which they are refined, depending on their geometrical size. increase the value to load lower lod tiles from the same view distance (increases performnace) - default: 16. | | [maxRequests?](./three-loader-3dtiles.loaderoptions.maxrequests.md) | number | (Optional) When thorttling requests, how many requests can launch simultaneously - Default: 64 | | [pointCloudColoring?](./three-loader-3dtiles.loaderoptions.pointcloudcoloring.md) | PointCloudColoring | (Optional) When viewing Point Cloud tiles, how should the points be colored ([PointCloudColoring](./three-loader-3dtiles.pointcloudcoloring.md)) - Default: PointCloudColoring.White | | [pointSize?](./three-loader-3dtiles.loaderoptions.pointsize.md) | number | (Optional) Point size for Point Cloud tiles - Default: 1.0 | | [preloadTilesCount?](./three-loader-3dtiles.loaderoptions.preloadtilescount.md) | number | (Optional) When using a three.js loading manager, do not call onLoad until this number of tiles were loaded - Default: undefined | | [shaderCallback?](./three-loader-3dtiles.loaderoptions.shadercallback.md) | (shader: Shader, renderer: WebGLRenderer) => void | (Optional) When viewing b3dm (mesh) tiles, a callback to update shader uniforms - Default: undefined | | [shading?](./three-loader-3dtiles.loaderoptions.shading.md) | Shading | (Optional) When viewing b3dm (mesh) tiles, which type of [Shading](./three-loader-3dtiles.shading.md) is used - Default: Shading.FlatTexture | | [skipLevelOfDetail?](./three-loader-3dtiles.loaderoptions.skiplevelofdetail.md) | boolean | (Optional) \_EXPERIMENTAL\_: Skip traversal mechanism, not yet supported. Default: false | | [throttleRequests?](./three-loader-3dtiles.loaderoptions.throttlerequests.md) | boolean | (Optional) Whether to throttle network requests so that tiles got out of the frame before the request launched, would not be requested - Default: true | | [transparent?](./three-loader-3dtiles.loaderoptions.transparent.md) | boolean | (Optional) Whether to set the material as transparent - Default: false | | [updateInterval?](./three-loader-3dtiles.loaderoptions.updateinterval.md) | number | (Optional) Interval in seconds for the traverser to check in an update is needed - Default: 0.1. | | [updateTransforms?](./three-loader-3dtiles.loaderoptions.updatetransforms.md) | boolean | (Optional) Whether to check if the tileset was transformed, set to true if the model is changes position in runtime. Default: true | | [viewDistanceScale?](./three-loader-3dtiles.loaderoptions.viewdistancescale.md) | number | (Optional) 0-1 scale for the LOD quality. A lower value loads tiles from lower LODs (increases performance). | | [wireframe?](./three-loader-3dtiles.loaderoptions.wireframe.md) | boolean | (Optional) When viewing b3dm (mesh) tiles, show meshes as wireframe - Default: false. | | [worker?](./three-loader-3dtiles.loaderoptions.worker.md) | boolean | (Optional) Whether to use workers when processing DRACO-compressed tiles - Default: true. |
