"Zookeeper is a big asset to the toolbox of any technical artist working with 3ds Max... At last we can create, edit and manage all the components of a 3ds Max scene and their relationships in one unified, clean graph;... If you like node-based systems and use 3ds Max, this one is a must." Full Text

"Having been a 'Maya guy' for many years prior to switching to Max, Zookeeper is exactly the tool I've been waiting for. Having the uncanny ability to seem familiar and innovative at the same time, Zookeeper takes the node-based workflow to the next level. I'd recommend Zookeeper to almost any 3ds Max user out there; from newbies to the most seasoned of artists." Full Text

"Zookeeper was another evolution for us, ... Marsel took it further and made a flexible UI that can show any max parameter and object enabling new workflows and speeding up the creation process." Full Text

"Once you get used to the workflow of Zookeeper you may not fully appreciate it until you have to go without it and then you will realize how it makes even the simplest tasks (like renaming multiple objects) faster and more enjoyable. I highly recommend Zookeeper for any serious 3ds Max user and I cant wait to see what EPHERE will innovate next!" Full Text
