Shader transform fade

Actually i’m learning and playing around with the shader transform from tonfilm. I’ve just a made a simple patch that deform the shape along with rms and fft analysis. Actually, I’m stucked with two features.

The first one, is that i would like to fade out the shape each time it has transformations (i’ve got the condition who’ll trigger the event) but dunno if i have to go into motion blur or feedback. I’d love to do it into shader and i’m sure it’s possible but i can’t figure how.

The second one is that i’d like to tweak each in the transformations into the shader (i mean translate, scale, etc). Through a spreads of 3 value coming from only one pin into the shader and then split the spread to different variables on the shader. (one for Pos.z, one for Poz.y…).

Cheers
