为什么顶点和片段着色不编译？

Question

我正在和R3F一起做阴影。然而，这个项目出了问题，经过几个小时的尝试，我还是找不到它。我正在编写GLSL文件的代码，我得到了下面的一个错误。

我想为这个项目创建一个云映像。我是从滴滴得到这份工作的。

顶点GLSL

uniform float rotation;
uniform vec2 center;
#include <common>
#include <uv_pars_vertex>
#include <fog_pars_vertex>
#include <logdepthbuf_pars_vertex>
#include <clipping_planes_pars_vertex>

varying vec2 vUv;

void main() {
    // #include <uv_vertex>
  vUv = uv;

    vec4 mvPosition = modelViewMatrix * vec4( 0.0, 0.0, 0.0, 1.0 );
    vec2 scale;
    scale.x = length( vec3( modelMatrix[ 0 ].x, modelMatrix[ 0 ].y, modelMatrix[ 0 ].z ) );
    scale.y = length( vec3( modelMatrix[ 1 ].x, modelMatrix[ 1 ].y, modelMatrix[ 1 ].z ) );

    vec2 alignedPosition = ( position.xy - ( center - vec2( 0.5 ) ) ) * scale;
    vec2 rotatedPosition;
    rotatedPosition.x = cos( rotation ) * alignedPosition.x - sin( rotation ) * alignedPosition.y;
    rotatedPosition.y = sin( rotation ) * alignedPosition.x + cos( rotation ) * alignedPosition.y;
    mvPosition.xy += rotatedPosition;
    gl_Position = projectionMatrix * mvPosition;
    #include <logdepthbuf_vertex>
    #include <clipping_planes_vertex>
    #include <fog_vertex>
}

片段GLSL

#pragma glslify: fbm3d = require('glsl-fractal-brownian-noise/3d')
#pragma glslify: snoise3 = require('glsl-noise/simplex/3d')
#pragma glslify: levels = require('./levels.glsl')

uniform sampler2D uTxtShape;
uniform sampler2D uTxtCloudNoise;
uniform float uTime;

uniform float uFac1;
uniform float uFac2;
uniform float uTimeFactor1;
uniform float uTimeFactor2;
uniform float uDisplStrenght1;
uniform float uDisplStrenght2;

varying vec2 vUv;

void main() {
    vec2 newUv = vUv;

    vec4 txtNoise1 = texture2D(uTxtCloudNoise, vec2(vUv.x + uTime * 0.0001, vUv.y - uTime * 0.00014)); // noise txt
    vec4 txtNoise2 = texture2D(uTxtCloudNoise, vec2(vUv.x - uTime * 0.00002, vUv.y + uTime * 0.000017 + 0.2)); // noise txt

    float noiseBig = fbm3d(vec3(vUv * uFac1, uTime * uTimeFactor1), 4)+ 1.0 * 0.5;
    newUv += noiseBig * uDisplStrenght1;

    float noiseSmall = snoise3(vec3(newUv * uFac2, uTime * uTimeFactor2));

    newUv += noiseSmall * uDisplStrenght2;

    vec4 txtShape = texture2D(uTxtShape, newUv);

    float alpha = levels((txtNoise1 + txtNoise2) * 0.6, 0.2, 0.4, 0.7).r;
    alpha *= txtShape.r;

    gl_FragColor = vec4(vec3(0.95,0.95,0.95), alpha);
}

错误来自控制台：

对于cloudVert文件，我也得到了相同的错误。

为什么不使用变量来存储文件脚本。

例如。

var _VS = `
uniform float rotation;
uniform vec2 center;
#include <common>
#include <uv_pars_vertex>
#include <fog_pars_vertex>
#include <logdepthbuf_pars_vertex>
#include <clipping_planes_pars_vertex>

varying vec2 vUv;

void main() {
    // #include <uv_vertex>
  vUv = uv;

    vec4 mvPosition = modelViewMatrix * vec4( 0.0, 0.0, 0.0, 1.0 );
    vec2 scale;
    scale.x = length( vec3( modelMatrix[ 0 ].x, modelMatrix[ 0 ].y, modelMatrix[ 0 ].z ) );
    scale.y = length( vec3( modelMatrix[ 1 ].x, modelMatrix[ 1 ].y, modelMatrix[ 1 ].z ) );

    vec2 alignedPosition = ( position.xy - ( center - vec2( 0.5 ) ) ) * scale;
    vec2 rotatedPosition;
    rotatedPosition.x = cos( rotation ) * alignedPosition.x - sin( rotation ) * alignedPosition.y;
    rotatedPosition.y = sin( rotation ) * alignedPosition.x + cos( rotation ) * alignedPosition.y;
    mvPosition.xy += rotatedPosition;
    gl_Position = projectionMatrix * mvPosition;
    #include <logdepthbuf_vertex>
    #include <clipping_planes_vertex>
    #include <fog_vertex>
}
`;

var _FS = `
#pragma glslify: fbm3d = require('glsl-fractal-brownian-noise/3d')
#pragma glslify: snoise3 = require('glsl-noise/simplex/3d')
#pragma glslify: levels = require('./levels.glsl')

uniform sampler2D uTxtShape;
uniform sampler2D uTxtCloudNoise;
uniform float uTime;

uniform float uFac1;
uniform float uFac2;
uniform float uTimeFactor1;
uniform float uTimeFactor2;
uniform float uDisplStrenght1;
uniform float uDisplStrenght2;

varying vec2 vUv;

void main() {
    vec2 newUv = vUv;

    vec4 txtNoise1 = texture2D(uTxtCloudNoise, vec2(vUv.x + uTime * 0.0001, vUv.y - uTime * 0.00014)); // noise txt
    vec4 txtNoise2 = texture2D(uTxtCloudNoise, vec2(vUv.x - uTime * 0.00002, vUv.y + uTime * 0.000017 + 0.2)); // noise txt

    float noiseBig = fbm3d(vec3(vUv * uFac1, uTime * uTimeFactor1), 4)+ 1.0 * 0.5;
    newUv += noiseBig * uDisplStrenght1;

    float noiseSmall = snoise3(vec3(newUv * uFac2, uTime * uTimeFactor2));

    newUv += noiseSmall * uDisplStrenght2;

    vec4 txtShape = texture2D(uTxtShape, newUv);

    float alpha = levels((txtNoise1 + txtNoise2) * 0.6, 0.2, 0.4, 0.7).r;
    alpha *= txtShape.r;

    gl_FragColor = vec4(vec3(0.95,0.95,0.95), alpha);
}
`;

它应该能工作
