Animating shaders/ material properties

Hi guys

I'd like to achieve this effect as an animation within Unity.

In Blender (above) I had two different materials set up and by animating the mix between the two you get an interpolation of the material properties.

I could swear I found a tutorial about creating animation clips for materials in Unity a while ago but I can't find it right now.

The two materials I'm going to animate between are a simple Transparent/diffuse procedural texture from Unity's in-built shaders



, and this 'ghost' shader that I downloaded from the asset store.

Any tips for how I'd go about doing this?
