构件无法贴图

Question

function createTexture(currentFragId) {
            var loader = new THREE.TextureLoader();
            var texturePath = './img.jpg';
            loader.load(texturePath, function(texture) {
                texture.wrapS = texture.wrapT = THREE.RepeatWrapping ;
                texture.minFilter = THREE.LinearMipMapLinearFilter;
                texture.magFilter = THREE.LinearFilter;
                texture.repeat.set(1, 1);
                var localmaterial = new THREE.MeshBasicMaterial({
                    side: THREE.FrontSide,
                    // depthTest: false,
                    depthWrite: false,
                    transparent: true,
                    map: texture
                });

                var geomface = oViewer.model.getFragmentList().getGeometry(currentFragId);
                var mesh = new THREE.Mesh(geomface, localmaterial);
                localmaterial.map.needsUpdate = true;

                oViewer.impl.matman().removeMaterial('meshBasicMaterial') ;
                oViewer.impl.matman().addMaterial('meshBasicMaterial', localmaterial, true) ;
                oViewer.model.getFragmentList().setMesh(currentFragId, mesh) ;
                oViewer.impl.invalidate(true);
            })
            
        }

使用此方法为构件贴图，但是有的构件无法显示贴图，是什么原因？另外如何为构件只贴一面图？side: THREE.FrontSide似乎只能去掉构件背面的贴图，四周还是有贴图
