Hi everyone! If you ever placed a strong light source behind your hand, you might have noticed how light is able to filter through the skin. Even more interesting is the fact that light "travels" inside the skin, and can sometimes make the entire hand glow. This optical phenomenon is called subsurfa

This is the complete series about subsurface scattering in Unity. Part 1. Fast Subsurface Scattering in Unity Part 2. Fast Subsurface Scattering in Unity You can download the Unity package for this project here ($10+ patrons only). As always, thank you for your support.

Most (if not all) optical phenomena that materials exhibit can be replicated by simulating how the individual rays of light propagate and interact. This approach is referred in the scientific literature as ray tracing, and it is often too computationally expensive for any real-time application. Most
