Hi Esther, The regular Carrara installation installs a bunch items to the Browser,I install things from the content cd as I need them to the browser of just to the file I am working on. It is nice just to know what is all on the content cd ,so I would just look over all the objects that are there. The browser is like a catalogue of items you can re-use in your scenes and is accessed by pressing Ctrl+B, a tray should open with different types of Objects,Shaders,effects,modifiers etc that you can Drag onto objects or into the scene. Look at pg 44-47 in the C4 manual on how to manage the browser. Carrara 4 doesn't have a Drop object feature like Bryce, you can use Collision detection(see image) to help placing objects on other objects. In C5 the replicators place the instances automatically on the terrain using the Hotpoint of the object as a reference point. Did you check out the quick start tutorials that come with Carrara , they should help you get up to speed. Let us know if you have any more questions. Mike
