Change Color of model from Down to up!

I created this small effect few days back

what i am doing here is, I am getting all the Triangles of sphere model and creating them as a new GameObject and then rotating them.

By creating this effect i got this idea of “can i change color of model from Down to up(triangle by triangle) to create a nice effect like model changing to something else?”

But i don’t really know how to do it!

i tried to get all the Triangles and vertices of the model but they don’t really have their own material data!

so i can’t really change the color.

Has anyone any idea on how can i do it?

Such effects are usually achieved by custom-made shaders. Try writing your own or find one which matches your needs.
