Hi Matt. In my experience Lagoa, for all it's cool potential, is just sooo slow and unstable.
On the last job I did I went through Lagoa, Momentum and Syflex. Lagoa was dropped very early on because of it's instability. Momentum is great but has the limitation I mention in this thread. Syflex handles that limitation with ease and is also amazingly fast and robust. But ultimately it's a poisoned chalice as it gives you no control whatsoever other than 'wind' or 'damp'... Basically Syflex speaks in caveman terms when it comes to simulation! DAN On Fri, Jun 22, 2012 at 4:33 PM, Matt Morris <matt...@gmail.com> wrote: > Have you thought about lagoa cloth?
