Hey everyone, I hope you will enjoy this new free tutorial. This is all about creating a "Vertex Density Heatmap" but I'm making this tutorial for people who are beginning with / want to learn Houdini while doing a cool tool :) 

   Contrary to my previous tutorial (Vegetation for games with Houdini), we will be more on the Technical Art side than pure Game Art ! I'll try my best to explain all important aspects of Houdini, and we will cover a lot of subjects ( Basic UI, Attributes, Vex, Vop,...) while working toward our goal : Creating a Vertex Density Heatmap.I take a lot of time explaining everything, but I feel it's important for people to understand what they are doing to make the information stick better, and be able to expand on it.If you want to support me, please consider buying my other (paid) tutorial here : (The first part are free on my Youtube channel) Foliage with houdini : https://www.udemy.com/houdini-game-art-foliage/?couponCode=TWITTER2

    Hi Alexandre!

    Awesome tool!
    I see you are using Near Point in VOP which is actually based on each points right ? Is it possible to make the tool to run through vertices?

      Thanks !
      You could put a fuse after loading the mesh, and split all the points so your point number = your vertex count

      Someone suggested me the pointvertices() vex function too!

        Thanks for replying!

        That is my a part of concern, because I watched gameloft's video about using Houdini in production a few month ago(where you introduced Vertex Heatmap tool), and I tried to recreate a tool that is based on vertices so I can do a subtraction on near vertex counts and near point counts to detect any potential bad geometry. But what bothers me is how Houdini has little support on vertices that somehow make it impossible(i.e. no functions like pointcloud or Near Point VOP). Do you have any highlights on that?

        Thank you again.
