hide/show layer during animation

Hello! How to hide/show layers @ animation using ipo curves or th else? I know I can do it hiding/unhiding layers manually & render series of frames but it takes too much time & I couldn’t save that changes in time. Sorry 4 my English & thx!

In Blender you can’t animate which layers are visible, but you can animate which layer an object is on. For example you can make objects suddenly appear by switching them from an invisible (unrendered) layer to a visible layer. Select the object, use M-key to move it to desired layer, I-key->Layer to key the change. There was discussion of this in this thread.

Thanx a lot!
