I would like to improve my viewport performance, when using complex scene with Multiple Forest objects. Is it possible ?

Step-by-step guide

There are two changes that may help:

a) Disable Camera clipping

Camera clipping is useful for large extensions of terrain, but forces to rebuild and redraw the Forest object more times (each time that view changes). Also, this disables the ability for the plugin to cache the geometry efficiently in the video card.

Depending of the scene, in some cases you will get better performance by enabling it, and others worse. In the latest Forest versions, the plugin suggest you turn on this option only when using large areas. So, just try both modes and compare. To disable it, turn off "Auto assign to active view" and click "Clear" in the Camera rollout.

b) Points-cloud

The points-cloud mode is a very nice way to represent the scene, but depending of the video card and the number of visible objects, it could have an impact on viewport performance. Sometimes may be useful to try other modes and compare (such as Display->Proxy->Pyramid).

Some tips about Points-cloud:

  • The total number of "points" is proportional to the number of visible Forest objects. In Forest 4 and above we included a new parameter, to modify the global density of dots easily.
  • To improve the display performance in Max 2013 and Nitrous, be sure to use Forest 4.x or greater, and the latest Max patch (Product Update 6 or greater).
