  1. Point Cloud Normals

    Hi all, just want to point anyone looking to solve this problem to this blog post by Jake Rice: https://jakerice.design/2018/09/19/Covariance-and-Principal-Component-Analysis/, which uses the covariance approach and some other fancy stuff to compute accurate (or close to accurate... how do we determine accuracy again?) normals.
  2. Hi all, I'm having an issue where my grains clip to the other side of the heightfield they are meant to be colliding with. This is affecting the animation and I'm pretty sure it's not supposed to be happening. If someone could let me know what I'm doing wrong I'd really appreciate it. Cheers grainsissue.hiplc EDIT: Solved by checking "Use Heightfield" on the terrain object inside the DOP.
