■ Raytrace map The mental ray renderer supports all Raytrace map settings except for the antialiasing parameters. ■ Reflect/Refract map This map tells the mental ray renderer to use ray-traced reflections and refractions. Most parameters are supported, but the parameters Blur Offset, First Frame Only, Every Nth Frame, and Atmosphere Ranges are not supported. NOTE The mental ray renderer does not fully support cubic maps for Reflect/Refract maps. It uses cubic maps if they have already been generated by the default scanline renderer, but it does not generate them. If Source > From File is active and the mental ray renderer can find the six cubic maps, it uses them. If Source > Automatic is active, or if the cubic maps cannot be found, the mental ray renderer generates ray-traced reflections or refractions instead. Enhancements to Standard Features The primary interface to the mental ray renderer consists of rollouts on the Render Setup dialog. To choose the mental ray renderer, use the Assign Renderer rollout on page 6135, as described in this procedure on page ?. In addition, object properties, lights, and the Material Editor have additional controls to support mental ray rendering. Last but not least, 3ds Max offers a special mr Proxy object for speeding up rendering of large, complex scenes. Object Properties Enhancements Parameters on the mental ray panel on page 322 of the Object Properties dialog support displacement as well as the mental ray indirect illumination features: final gather on page 6295, caustics on page 6255, and global illumination on page 6261. mental ray Proxy Object When working with high-resolution geometry, you can save memory and translation time by using the special mr Proxy object on page 597 as a stand-in for your models. mental ray Renderer | 6241
