TIP If you have a transparent object such as glass, and Enable Self Reflect/Refract is on, you don't have to make the object 2-sided on page 7893. The raytracer sees back faces when exiting refractive objects. Reflect/Refract Material IDs When on, the material reflects effects assigned to material IDs in the renderer's G-buffer on page 7991 on or off. Default=on. By default, Raytrace material and Raytrace map reflect effects assigned to a material's ID, so that G-buffer effects are not lost. For example, if a raytraced object reflects a lamp made to glow with the Video Post Glow filter (Lens Effects Glow), the reflection glows as well. Raytracer Enable group These two check boxes turn raytracing of reflections or refractions on or off for this material. If you are using the Raytrace material to create only reflections or refractions, turn off the one you aren't using to improve rendering time. Raytrace Reflections Turns raytracing of reflective objects on or off. Default=on. Raytrace Refractions Turns raytracing of transparent objects on or off. Default=on. Local Exclude Displays the local Exclude/Include dialog on page 5519. An object that is excluded locally is excluded from this material only. TIP Using exclusion lists is one of the best and simplest ways to speed up the raytracer. Bump Map Effect Adjusts the effect of bump maps on raytraced reflections and refractions. Default=1.0. Falloff End Distance group Reflect Dims reflections to black at this distance. Default=100.0. Refract Dims refractions to black at this distance. Default=100.0. NOTE The toggles for Reflect Falloff and Refract Falloff aren't animatable. Raytraced Reflection and Refraction Antialiaser group Controls in this group let you override the global antialiasing settings for raytraced maps and materials. They are unavailable if antialiasing is turned 5508 | Chapter 19 Material Editor, Materials, and Maps
