Runtime sculpting - procedural mesh generation

Hi all,

Just a little advice on which documentation to read up on please.

I am looking to create an app where the user will be given a piece of clay (or something similar) and on touch… be able to essentially sculpt the clay. How much of the clay is ‘taken away’ will depend on length of touch.

Now, I have used my limited Unity knowledge to suss out that I am looking for procedural mesh generation but I am hugely unfamiliar with this so could anybody please point me to a link/plugin/doc link to anything that might help me here? I cant seem to find much on this anywhere but for all I know I may be looking/searching for all the wrong things/classes.

Thanks all

–Eric
