Sequence image for texture?

Hi,

I want to use a sequence image for texture (a explosion sequence).
I found some information in here, http://wiki.unity3d.com/index.php?title=Animating_Tiled_texture
but it’s seen a little old and the code don’t work in Unity 2017.1

Does anyone can give me some idea please? both sequence image and sprite sheet is ok.
btw, I want assign to mesh, not particle.

Thanks very much.

Thanks, Just found there’s a similar post in this forum and got the idea.
