Hi. After my fluid simulation has settled, I want to freeze it. The scene will potentially contain a lot of ice at any given time, but a limited amount of flowing liquid, so for efficiency I'm guessing the best thing to do is to create a mesh from the fluid surface at the moment it freezes.
So my idea is to grab all the particle positions, write them to a grid and run a Marching Cubes algorithm; does that seem feasible? Am I reinventing the wheel in making a feature Obi already has? And is there anything I need to know about how to interpret the Obi parameters, in order to for the ice mesh to look as similar as possible to the original fluid? (e.g. I'm unsure how to simulate Thickness Cutoff...)
