Mash falloff and mix arnold material

[giuseppe.milani]

Hi guys, for my next project I'm trying to create the same mix of material like this video:  https://www.youtube.com/watch?v=zB6RfPV_QkA

The problem is not the animation but the mix/reveal material, I can't find a right or "easy" way to do it!. I have tryed aiCurvature, vertex map, aimixlayer, ramp, aiuserdatacolour, but I'm blocked.

Someone can help me with it?

Here you will find the base scene on which I am testing the mix.

Thanks a lot!

i found a solution, probably it can be done in another way too. I connected a projection node to the mix shader, connecting a rampRgb node as an image to the projector, so as to be able to modify the projection as desired. The projection is then inside the locator where the falloff is inserted
