| TG Reflectance Ramp |
| Just some spheres on the oft-seen test “chequered ground plane”. This is the “Neon Edge” preset from TG Reflectance Ramp, the preset making the Ambient value high at the edges, and low elsewhere. Weird, but I like it! |
| What It Does This is a fairly conventional reflectance shader, except that the Diffuse, Specular, Reflection and Transmission channels can be varied with angle of view, each using their own independent Ramp. This allows the creation of fresnel style fall-off for reflection, for example, as well as for more unusual effects, such as having the diffuse fall off for surfaces at right angles to the camera (giving a dark “edge” or “rim” to an object), for having specular highlights brighter when facing the camera, and so on. This can be useful for producing some interesting and dramatic materials, or for special effect type materials (eg combined with TG Glow shaders, to add or exagerrate lighting at the edges of objects, for unusual “see through” materials). |
