hi,
IceMaterial.js
const glslify = require('glslify');
const path = require('path');
const assign = require('object-assign');
const defined = require('defined');
// This is the original source, we will copy + paste it for our own GLSL
// const vertexShader = THREE.ShaderChunk.meshphysical_vert;
// const fragmentShader = THREE.ShaderChunk.meshphysical_frag;
// Our custom shadersshow original

#ifdef USE_TRANSLUCENCY
uniform sampler2D thicknessMap;
uniform float thicknessPower;
uniform float thicknessScale;
uniform float thicknessDistortion;
uniform float thicknessAmbient;
uniform vec2 thicknessRepeat;
#endifshow original
I found pbr-based sss by @mattdesl and as you can see, there is only a fragment shader.
so, I tried to use it with extended MeshStandardMaterial. but it does not work at all.
I assume that the shader is a bit old so it doesn’t match with the latest version of MeshStandardMaterial’s vertex shader.
Do you have any example of sss with standard material?
thank you!

You may have seen this threejs example, but just in case: three.js examples
Also, I’ve extracted that SSS part of the code and made it into a node for Polygonjs , making it easier to setup. And you can always copy the GLSL code into your own project (from the right panel in the video).
