Hi Lala,
just wanted to confirm, is it same as zoo?? is it zoo version of autodesk??
Slate is a schematic material editor. Zookeeper provides schematic interface to editing materials as well but it also does so for the rest of the scene (objects, modifiers, controllers, textures, materials, shaders, and anything else thats used inside a scene). On top of that there are very elaborate tree views and palette views for the scene.
In other words- slate is a sub-set of Zookeeper's functionality. Personally I use Zookeeper for much more than material editing.
or they have got zoo and put that in 3dsmax??
No, Autodesk did not buy Zookeeper :)
Another selling point is that Zookeeper is under active development. We release about two new builds each week and fix bugs and add features very quickly.
Hope that helps!
