Hi everyone!
I need some help. I am trying to create stylized rock pattern and now i want to add some cracks on its corners. Those cracks should be triangular and be of different sizes. And now it's a bit tricky to me how achieve that result. Some people tell me to use slope blur but using slope blur usually gives a rounded result, but what i need are cracks with sharp corners. Do someone have any ideas how to make it? I'll be very glad for any help.

Result should be something like this

Hello,

 

You can use a Crystal 1 generator to chip away hard triangular shapes from tiles. See attached package tile_cracks.sbs for an example.

Another approach could involve generating a crack shape using a combination of Crystal 1 and Cross Section and using a Splatter node to distribute them. See attached package tile_cracks_2.sbs for that option.

In both examples, a Vector Warp node is used to break the continuity of cracks across neighbour tiles.

 

I hope this is helpful!

Another alternative for hard edge chips/cracks is to make the hard edges and use a flood fill mapper to distribute them
