gammaPass一定要放在最后面add!!!
import { GammaCorrectionShader } from 'three/addons/shaders/GammaCorrectionShader.js';
import { ShaderPass } from 'three/addons/postprocessing/ShaderPass.js';
const gammaPass = new ShaderPass(GammaCorrectionShader);
effectComposer.addPass(renderScene)
effectComposer.addPass(gammaPass)
有时候这个后期处理的顺序 很重要 都是经验
