I would like to create a scene where someone destroys an object (stone) with a pickaxe. With each hit the cracks are getting bigger until that stone will fall apart.
This is my plan for the cracks: I'd create 3 different images which show a procedure of these cracks. Then i'd use them in a displace modifier and try to adjust the timing when the pickaxe hits the stone.
But how can i combine two displace modifiers (i've used one for the stone itself, too) and make the cracks getting bigger and deeper?
Or is my way a bit too inconvenient. I think i could also try to use nodes, but i don't know which.
