For scattering I heavily used my “AL TOOLS ” and the “AdvancedScatter” to quickly create complex scattering systems for all the different elements in Houdini. I have been working on a v6 that should really help make things easier and faster… This version won’t be retro-compatible with past projects though as I am changing some core features. This update will be reflected in my current products and orbolt once I push the testing phase a bit more.
