A "psychic" shader mod; development begins...
A Psychic Shader Hack
Hi. I recently wrote a crazy shader hack that tries to make out the artistic intent to represent metal, and where it decides that metal was intended, changes the diffuse and specular colors to actually best represent metal. The hack works about 50% of the time... It misses very few metals; but it converts many colors NOT intended as metals into metals, foremost among them human skin (which non-the-less becomes a believable representation of sun-tanned skin, as oppo
Okay, I think I got it; hope it works.
Includes metal and skin detection. Metal is enhanced by matching hue of diffuse and specular and ensuring that diffuse saturation is higher than specular's, but not much higher; and that specular value is higher than diffuse. Skin is enhanced by adding partial Fresnel specularity to it, of low gloss (skin is colored in diffuse, but shimmer-reflects white), and by adding a hack to make it seem like it gives a hint of red translucency.
Unfortuna
