3d - Texture and material loading issue with THREE.OBJLoader2.WWOBJLoader2 -


i using three.js include 3d models (obj + mtl format) in web application. size of 3d models big( 35-70mb ), need load them using web worker in order avoid freezing web page. have tried web worker based method using three.objloader2.wwobjloader2, 1 texture getting applied 3d model. have tried using different 3d models , result same. 

reader.addeventlistener( 'load', function ( event ) {      var uint8arraynew  = new uint8array(event.target.result);     objbuffer = uint8arraynew;      initpostgl();     prepdata = new three.objloader2.wwobjloader2.prepdataarraybuffer(         workerinput.obj,    // overall model name         objbuffer,          // obj file arraybuffer         workerinput.path,   // texture path         mtlstring           // mtl string     );      objectgroup = new three.group();     objectgroup.name = workerinput.obj;      prepdata.setscenegraphbasenode( objectgroup );     prepdata.setstreammeshes( true );     wwobjloader2.setdebug(false);     wwobjloader2.preparerun( prepdata );     wwobjloader2.run();  }, false ); reader.readasarraybuffer( objectasbuffer );
