MutliScatter is a plugin for 3ds Max, which allows you to create large scenes with many identical objects without have each individually stored in your memory. MultiScatter creates only references therefore saves a lot of memory and rendering time. It runs with V-Ray, Mental Ray, Corona and Octane.
If you created your scene using this plugin, just ask us and we will support you getting your project rendered no matter how large your array of MultiScatter objects is. ;-)
