Houdini simple mesh erosion

I made a video for my artstation portfolio
Houdini simple mesh erosion (rain erosion), texturing, unreal engine tests
Tutorial:
Here is all about how to setup particles, collision for object, and the most crucial thing how to generate wet maps from rain on a mesh, after generating masks you can simply put labs triplanar displace node and set mask name attribute in "use displacement scale attribute" tab. I simply used masks from wet maps to displace geometry :) you can simulate whatever you want in this case rain, tornados, swirly winds, etc hope it helps!
• Tutorial 3 - Rain Syst...
You can also do displace with this code, but it's not for triplanar - it works good for certain X, Y, Z axis.
// Create a wrangle node and set it to run over points or vertices.
// Make sure the input geometry contains a "displacement" attribute mask.
vector displacementAmount = set(0, -0.1*0.0025*$F, 0); // Adjust this vector to control the displacement amount.
// Retrieve the attribute mask from the geometry.
float mask = @rain_erode;
// Calculate the displacement vector based on the attribute mask.
vector displacement = displacementAmount * mask;
// Displace the position of the point or vertex.
@P += displacement;

can you share the set up? I can buy it from you in Gumroad for example

Hey there, do you happen to still have the Wrath and Sacrament producer edition files? They have been scrubbed off the internet and every other channel who has/had them is inactive. Thank you :)

how did you do erosion in a mesh? i only know how to do it with heightfields. Thanks!!

@@ShibaInuClassical I will try it . Thanks a lot!!!

is this rain erosion?
