Big news for upcoming effects:
Iridescence has been successfully integrated! The effect is achieved using the sun direction specular (Blinn-Phong) and angle of the surface (Fresnel) to drive a gradient that provides the color warping. This effect has been added to the Metal Twine and Neotype presets. You have a range of controls from intensity and color shift to the frequency of the color warping and specular power. It’s as easy as toggling a switch, and your tiles will shimmer with color!
Work is progressing on a Rough Diffuse to make rough and dusty surfaces like stone, bricks, unpolished tile, and untreated wood look proper. Lambertian diffuse darkens objects around the edges, but rough surfaces actually brighten. So, we need to combat that diffuse with our own mixture. I’m trying to find the right blend so colors don’t become desaturated, and it is proving to be a daunting task. But the end result should be an easy toggle-on for better diffuse shading, automatically calculated based off of the material’s roughness, with a simple intensity parameter to scale the effect.
