three.js-FXAA在从r65更新到r68时出现错误

我刚刚从three.js的r65切换到r68，在使用FXAA后期处理着色器时，我在浏览器控制台中遇到以下错误：

THREE.WebGLProgram:gl.getProgramInfoLog（）警告：碎片着色器未读取顶点着色器“vUv”的输出。。。3.js:25545

我用r65尝试了相同的代码，但没有出现错误。着色器似乎工作正常，但我不喜欢在控制台中出错。以下是相关代码：

// COMPOSER

this.renderTargetScene = new THREE.WebGLRenderTarget( this.width, this.height );
this.renderTargetScene.minFilter = THREE.LinearFilter;
this.renderTargetScene.magFilter = THREE.LinearFilter;
this.renderTargetScene.format = THREE.RGBAFormat;
this.renderTargetScene.stencilBuffer = true;

this.sceneComposer = new THREE.EffectComposer( this.renderer, this.renderTargetScene );

this.sceneCubeUnderPass = new THREE.RenderPass( this.sceneCube, this.cameraCube );
this.sceneCubeUnderPass.renderToScreen = false;
this.scenePass = new THREE.RenderPass( this.scene, this.camera );
this.scenePass.renderToScreen = false;
this.scenePass.clear = false;

this.effectFXAA = new THREE.ShaderPass( THREE.FXAAShader );
this.effectFXAA.uniforms.resolution.value = new THREE.Vector2( 1 / window.innerWidth, 1 / window.innerHeight );

this.effectCopy = new THREE.ShaderPass( THREE.CopyShader );
this.effectCopy.renderToScreen = true;

this.sceneComposer.addPass( this.sceneCubeUnderPass );
this.sceneComposer.addPass( this.scenePass );
this.sceneComposer.addPass( this.effectFXAA );
this.sceneComposer.addPass( this.effectCopy );

onWindowResize: function() {

    this.width = window.innerWidth;
    this.height = window.innerHeight;

    iss.windowHalfX = this.width / 2;
    iss.windowHalfY = this.height / 2;

    iss.camera.aspect = this.width / this.height;
    iss.camera.updateProjectionMatrix();

    iss.cameraCube.aspect = this.width / this.height;
    iss.cameraCube.updateProjectionMatrix();

    iss.renderer.setSize( this.width, this.height );

    iss.effectFXAA.uniforms[ 'resolution' ].value.set(1 / ( this.width ), 1 / ( this.height ));
    iss.sceneComposer.setSize( this.width, this.height );

},

render: function(){

    var timer = -0.0002 * Date.now();

    iss.cameraCube.rotation.copy( iss.camera.rotation );

iss.sceneComposer.render( 0.1 );

},

任何帮助都将不胜感激。

这只是一个警告

您可以通过编辑

examples/js/shaders/fxashader.js

并删除引用

vUv

的所有行来修复它，因为不使用该变量

three.js r.68

我想我们也应该在lib中删除它：U
