Hello !!
I am creating an animation of sand turning to another material.
I have sand made with particles and slowly swirling. (Something like this tutorial - https://www.youtube.com/watch?v=nM3dsMdI9Lc ). Now I need to somehow turn the sand to a different material. I want the sand particles to rise and drop down, changing their material at the same time. But i want this is to happen gradually in the shape of one single concentric circle starting from the center and continuing outwards.
All help appreciated.
