我不知道它是否有意义，但道格的回答是对的
我只是想补充一点，我本人设法使用相同的资源完全按照自己在游戏中构建的动画来重新创建动画，请看这里

precision highp float;
uniform float uTime;
uniform sampler2D uSampler0;
uniform sampler2D uSampler1;
uniform sampler2D uSampler2;
uniform sampler2D uSampler3;
uniform sampler2D uSampler4;
uniform sampler2D uSampler5;
varying vec2 texCoords;
void main(void) {
float t = uTime;
vec3 mask = texture2D(uSampler1,texCoords).rgb;
vec4 img = texture2D(uSampler0,texCoords);
img.rg*=1.1;
vec2 flow = texture2D(uSampler3,texCoords).gr;
flow.y+=t*3.;
vec4 plas = texture2D(uSampler2,flow*1.2) * mask.r;
plas *= 15.5;
plas *= vec4(0.239, 0.224,0.488,1.);
vec2 ct = texCoords;
ct.y -=t*0.5;
vec4 clouds = texture2D(uSampler4,ct*2.);
float clouds_a = clouds.a;
clouds *= 4.5;
clouds *= vec4(0.275,0.23,0.161,1.);
clouds_a *= mask.b;
img += clouds * mask.b;
img += plas * mask.r ;
img += (sin(t*15.)+1.) * mask.g * vec4(0.239, 0.224,0.488,1.)*2.;
ct.x += t * 0.5;
vec4 clouds_overall = texture2D(uSampler5,ct * 0.5);
clouds_overall *= vec4(0.275,0.23,0.161,1.);
gl_FragColor = img +clouds_overall;
