Atom Posted October 18, 2016 Share Posted October 18, 2016 Hi All, I have always been disappointed by all 3d packages ability to emulate wind. Sure, most make something called wind but it is just a re-packaged noise generator. Does anyone have any better recipes for emulating wind? PopWind does have a velocity direction field, but I don't feel like it outputs the ebb and flow that defines natural wind. Let's pretend we want wind to blow from East to West so we setup a velocity in the X axis. But wind is not a fan. A fan would blow continuously in one direction, but wind kind of pushes then stops, maybe flows a little the opposite direction then takes off in the direction again. Can PopWind be configured to act more like wind and less like a fan? I have attached the setup I am working with. Basically some instanced spheres floating in a volume. ap_geo_in_slow_floating_volume_101816.hipnc Quote Link to comment Share on other sites More sharing options...
fencer Posted October 18, 2016 Share Posted October 18, 2016 How about using multiple wind, one for main direction, second with large swirl scale for periodic movement Quote Link to comment Share on other sites More sharing options...
Atom Posted October 18, 2016 Author Share Posted October 18, 2016 That might help out, use two. I kind of headed down a similar path, combining multiple forces, using CHOPS to create a more random motion with lag. Instead of using PopWind, I use PopDrag and set the direction equal to the output from the CHOPs. Because the Air Resistance seems to just be a multiplier on Wind Direction per axis you can use VEX to randomize the strength of the air resistance on a per-particle basis. This gives a kind of suspended in gel motion that still follows the master noise generator. ap_chop_wind_101816.hipnc 1 Quote Link to comment Share on other sites More sharing options...
