[Three.js模型在添加点光源时消失

Question

我正在一个项目中，我将多个着色器应用于一个对象。基本场景使用定向灯照明，但是当我在场景中添加点光源或聚光灯时，对象会完全消失。我在场景中还有其他物体不会消失，因此我只能假定它与应用的着色器和点光源有关。这是我正在使用的着色器的摘录：

var shader = THREE.ShaderSkin[ "skin" ];

            var uniformsUV = THREE.UniformsUtils.clone( shader.uniforms );

            var textureLoader = new THREE.TextureLoader();

            uniformsUV[ "tNormal" ].value = textureLoader.load( "obj/me/all_skin_hi1_normal.jpg" );
            uniformsUV[ "uNormalScale" ].value = -1.5;

            uniformsUV[ "tDiffuse" ].value = textureLoader.load( "obj/me/all_skin_hi1.jpg" );

            uniformsUV[ "passID" ].value = 0;

            uniformsUV[ "diffuse" ].value.setHex( diffuse );
            uniformsUV[ "specular" ].value.setHex( specular );

            uniformsUV[ "uRoughness" ].value = 0.185;
            uniformsUV[ "uSpecularBrightness" ].value = 0.7;


            var uniforms = THREE.UniformsUtils.clone( uniformsUV );
            uniforms[ "tDiffuse" ].value = uniformsUV[ "tDiffuse" ].value;
            uniforms[ "tNormal" ].value = uniformsUV[ "tNormal" ].value;
            uniforms[ "passID" ].value = 1;


            var parameters = { fragmentShader: shader.fragmentShader, vertexShader: shader.vertexShader, uniforms: uniforms, lights: true };
            var parametersUV = { fragmentShader: shader.fragmentShader, vertexShader: shader.vertexShaderUV, uniforms: uniformsUV, lights: true };

            var material = new THREE.ShaderMaterial( parameters );
            material.extensions.derivatives = true;

            var materialUV = new THREE.ShaderMaterial( parametersUV );
            materialUV.extensions.derivatives = true;

尝试更新到较新版本的引擎。这为我解决了。
