Each frame may take several minutes of computation. When processing 4D sequences you have thousands of frames, which may take weeks.
R3DS Rush allows running the computation on dozens of machines with just a few clicks. You can stop, pause, track progress, and assign different projects to different machines from a single easy-to-use interface.
It works in combination with R3DS Node, which is a headless computational node, so that you don’t need to buy a R3DS Wrap4D license for every machine.
