Question Chunk lighting

I was wondering if anyone knew how to do a chunk lighting system similar to the one in baldis basics plus like this


I would really appreciate it as I have been trying to figure out how to do it for a couple months now

 

Is that lighting dynamic or static? Does it change? Many approaches you could take, but need more information before we take one.

The simplest (and silliest), would be to have separate materials for each section of the wall and manually set them to darker colors as you go along? It's not efficient, but if you are going for baldi's complexity in terms of graphics, it should be fine.

 

It is dynamic lighting, and it can change colour and position. This is what it looks like, and if you look closely, you can see that the big cake in the middle has parts of it changing different colours because they are in individual chunks and the cake is just one big mesh, but if it was made so that it just changed the main colour of the object, it would change the entire thing instead of the different parts and I was hoping I could get something like this.
