Help for 3d text

Hi there,

I'm trying to animate a 3D text with three animation :

1) Z-offset IN
2) Opacity IN
3) Blur IN

As you can see here :

I only managed to do 1 and 2

Any idea about How to ?

Thank You

maybe...

1. render out the letters seperate, and blur them after the 3d render, and then merge them togehter

2. create a "fake" z-depth Map with a texture on your Letters, to use a DepthBlur
