Craquelure

[darkfrei]

Hi all!

I want to make the Craquelure, do you have any idea how to make it procedurally?

I think Voronoi could be the solution. Maybe with multiple layers

I've also think about the Voronoi, maybe find the critical values near the cell end and make small distortion for that distance. Maybe 1 pixel + some percentage value from distance of current pixel to cell node.

So the needed functions are:
Poisson discs to make nodes on quasisame distances -- 2023-07-15 done: viewtopic.php?p=255776#p255776
Voronoi polygons with this nodes
Noise for value random for crack thickness
Distance to the node for crack thickness

I would study some Voronoi based crack shaders. There are many shaders for cracks in terrain textures, etc where only the lines are visible.
