How to make an object evaporate?

Question

Unity

in general, I tried to make the object evaporate did this

for(; items[i].GetComponent<MeshRenderer>().material.color.a<0; items[i].GetComponent<MeshRenderer>().material.color.a -+10)
{
destroy (items[i]);
break;
}

what do you advise?

Answer 1

It seems that the particles had an option for them to fill the volume of the figure. And then you adjust the effect of evaporation.
