go to edit mode and select a row like this















duplicate it and sprate it like me














convert it to curve


















give it some depth











add subdiv modifier










convert it to mesh again















add displace modifier

















work on strength value until you get somthing you like or just add those numbers there (0.1 is good)











click on the icon that looks like two beans

choose the cloud






now play with size value until you get something you like













now if you look at it you see that this two mesh are ugly


its like toothpaste around the pipe dose not feel real



to kinda fix that you select the nearest vertex rows to the other mesh and assign them to a new group








then you add a data transfer modifier and set the source othere mesh and on vertex group choose to one that we made



















new enable face data corner and set it to custom normals






also disable outline






now about the data transfer modifier : its not for every shapes keep that in mind
