I've always used 'vdb from polygon' cos it sounded cool, and always fought it to get nice shapes. Turns out I've been wrong this whole time, and should've been using the cloud sop. Much nicer controls, works great with cloud noise, I'm an idiot.

Best way to learn chops in Houdini? Learn chops in Touch Designer. Install it, "Help -> Operator Snippets", chops menu. Realtime thumbnails too, don't get that in Houdini! Most entries have many examples, use the little 'next' button in the text field. #sidefx #touchdesigner
