Scatter an object on the surface of a mesh with different distribution methods

summary (oneliner)

Use various distribution methods to place many instances of a geometry along the surface of a mesh.
The following distribution modes are available:

  • VERTEX - Will only add an instance to a vertex point
  • TRIANGLE CENTER - Adds an instance to the center of a triangle
  • TRIANGLE SIDE - Adds an instance to the sideof a triangle
  • RANDOM TRIANGLE POINT - Adds an instance to a random point inside a triangle
