wreath Posted February 5, 2020 Share Posted February 5, 2020 (edited) Hey guys, I have a pretty simple scene here where I emit some particles and using particles to create density + velocity in a pyro sim, two unexpected things happening; 1 - Even if I turn off the Volume source (the one brings velocity) there still some velocity exist in the pyro (showing up at guide) 2- Emitted smoke tend to go dissipiate a little bit and move downwards (i expect it to be just frozen in mid air) even tho dissipation is off and there is no low temperature or too thic heavy smoke exists. Anyone can shed some light? thanks! VelocityProb.hip Edited February 5, 2020 by wreath Quote Link to comment Share on other sites More sharing options...
evanrudefx Posted February 5, 2020 Share Posted February 5, 2020 (edited) 1. the velocity is because of the gravity node 2. the smoke moves down because of gravity node disable the node and it works as you would expect : ) Edited February 5, 2020 by ejr32123 1 Quote Link to comment Share on other sites More sharing options...
wreath Posted February 5, 2020 Author Share Posted February 5, 2020 Oh!! there is no single parameter left unchecked and i forgot about gravity thanks Evan Quote Link to comment Share on other sites More sharing options...
