Developer Updates Realistic Skin Shader Made with Godot
MatMADNESS shared how they achieved a more realistic look.
3D Artist MatMADNESS showcased updates on their Godot skin shader, sharing technical details of the implemented changes.
The artist noted that the WIP shader needed further work, with one of the key areas being the reduction of the "plastic/rubber/wax look." To do that, MatMADNESS shared that they mixed the fresnel properties of the Burley algorithm with their custom Lambert implementation and tweaked the way the surface falloff behaves.
The developer also made the skin softer based on the light's specular property, which implies that if the light has a low specular value, the skin falloff appears softer, but that only works for the areas affected by that light. The artist also implemented a new Interleaved Gradient Noise for the SSS; it is now a one-line code instead of a texture. Apart from this, MatMADNESS changed the tonemap from ACES to Agx to achieve a more natural look. They also introduced a custom LUT for Agx, aiming for clean and natural texture details.
The creator plans to share the updated version on GitHub. In the meantime, you can check out the current version.
Before, MatMADNESS showcased an impressive parallax effect and showed how it was made with Blender's shader nodes:
