Or: function fadeInScene() { Effect.ShadersStore['fadePixelShader'] = 'precision highp float;' + 'varying vec2 vUV;' + 'uniform sampler2D textureSampler; ' + 'uniform float fadeLevel; ' + 'void main(void){' + 'vec4 baseColor = texture2D(textureSampler, vUV) * fadeLevel;' + 'baseColor.a = 1.0;' + 'gl_FragColor = baseColor;' + '}' let fadeLevel = 1.0 const postProcess = new PostProcess('Fade', 'fade', ['fadeLevel'], null, 1.0, c…
