snoot 9 Posted July 6, 2018 Hi guys, I'm attempting to get the thickness of an object and use this to blend between two pbr layers - in this case a sharp refractive layer into a sss-y one. I could sample an sdf volume on disk and read the thickness from there. But I'm wondering is there a way to do this at render time. For example, catching the position of a ray entering and exiting a surface with lots of sample. Any ideas? Example scene much appreciated! Thanks. Share this post Link to post Share on other sites
davpe 183 Posted July 8, 2018 hi, i think you should be pretty much able to get the thickness if you feed an occlusion shader by inverted normals: 1 Share this post Link to post Share on other sites
