Fade in and out in 2.57

Hi, I am new to Blender and am using it for my MA dissertation. Please could someone explain, in the most basic way possible please :o, how to fade objects in and out of an animation?

I am trying to show the chronological development of a building and want to do an animation illustrating this, but I don’t know where to start.

Thanks very much.

In the forum list a bit further down is the “support” section. Questions like this should be addressed there…

You’d be best using render layers and combining them in the compositor or sequence editor… in the sequencer the opacity of a layer can be animated… in the compositor you could animate the mix value
