Butachan Posted April 29, 2016 Share Posted April 29, 2016 Hi, I am relatively new at Houdini and I am sure I am making a few things quite inefficiently. But this is one I am pretty sure I must be doing it quite terribly so: Basically I am doing a small flock simulation from scratch (which my producer gave me a whole day and a half to do, ) with a animated loop for the bird instance (wich I also had to do on the same day an a half). Now, when using instances the animation works super fast, but once I offset the loop with a copy stamp technique on a time blend everything becomes quite slow....understandably. The technique I got it from Peter Quint tutorial here: https://vimeo.com/24969874 And it is quite useful (thanks Peter) but it is 5 years old! I wonder if nothing has changed since then. Because as I said is amazing how fast using instances Houdini is but as soon as I use the copy stamp technique, not so. And I have 200 birds only.... i cannot imagine the cost if it is 5000 particles. Quote Link to comment Share on other sites More sharing options...
