Rendering with mental ray and 3ds Max Figure 6.115 The attenuating reflections now keep the viewer's interest focused on the truck. objects in a scene. Many people still believe that reducing the number of polygons in the scene is the only important aspect of efficiency in viewpoints. However, if you have a scene with 10 objects with a total of 1 million polygons, it will be much more efficient to work with than a scene with 1000 objects and a total of 1 million polygons. Each object contains something called node space that must be stored in memory. You should know that creating Instance or Reference clones makes your scenes more efficient because each of those clones can refer back to the original object's node space, thereby saving memory. Another powerful tool you have in creating more efficient scenes is the mr Proxy objects. Let's learn about some of the options available with mr Proxy. Proxies are more efficient than Instance clones because the clones must still display the polygons, whereas the proxies do not. 6.5.1 IntroductiontomrProxyobjects 3ds Max 2010 allows you to substitute complex geometry with proxy objects that display as simple vertices or cubes in the viewpoints but render as complete objects. This reduces the amount of work the computer must do to display these complex objects in the viewpoints. In this section you will learn to Create mr Proxy. Use Zap Anderson's script for creating multiple proxies. Use Bobo's script for particle proxies. Let's take a scene that has an animated tree and turn it into an mr Proxy and then clone those trees for efficient viewport display. 6.5.2 Geometryproxy You must first create the mr Proxy standing object in the scene and then tell it which object it will be repre- senting. The tree in the scene has an animated Skew modifier that gives it a little bit of motion, as if it were blowing in the wind, and this must be considered in the proxy object. 208
