Update a texture at runtime using UV

Hello,
I have created a small script that procedurally creates a tilemap. Each tile has 4 vertices and 4 uv values, wich are then used to find a tile in an atlas.
Now, I'd like to change the uv values of a particular tile at runtime, so i can change the texture on that tile. Is it possible? I have tried changing the values in the uv array but that didn't work, is there something else i have to do? Do i have to rebuild the whole mesh to do it?

Thanks in advance!

I actually found the answer. Turns out the uv array you're trying to change is a deep copy of the actual uv array. (Why? I dunno). But the answer's explained fully here:
