Alpha fade

Hello - I’m a real newbie here…

I have managed to animate an object fading in transparency by animating the alpha transparency value. The only problem is, it seems to not fade from transparent and then into full colour, it just goes black and then fades in from that.

How do I make an object fade in through different levels of transparencey without the black colouring of the object?

Thanks

Just turn on ZTransp in the Mirror Transp (need a better name) panel of the Material window (F5).
