yjcnbnbnb200 Posted March 7, 2014 Share Posted March 7, 2014 I run a smoke simulation, smoke run along a custom velocity field which is imported by dop vector field. I need to improve more detail and curl to fluid, so I turn on disturbance in pyro solver, but when I play the rendered image in Nuke, the whole smoke shake every frame, when I turn off disturbance, everything is Ok, but the detail is missing, so anyone knows the reason?

yjcnbnbnb200 Posted March 7, 2014 Author Share Posted March 7, 2014 As when you run the simulation you can see shaking especially at the end part of the trail. It is artifact should be deleted. shot_v010_office_l.hip Quote Link to comment Share on other sites More sharing options...
yjcnbnbnb200 Posted March 10, 2014 Author Share Posted March 10, 2014 the shaking dissappear after changing disturbance to turbulence in Pyro Solver, why? I dive into the node and found that disturbance change temperature field in the end and turbulence change velocity field in the end. Quote Link to comment Share on other sites More sharing options...
yjcnbnbnb200 Posted March 11, 2014 Author Share Posted March 11, 2014 (edited) Another problem, as you can see in viewport, low density area has horizon and vertical gaps inside my density volume and in render image also these gaps in volume, I use a sop level custom field along the curve then pipe into dop network using sopvectorfield and copy method, so how can thses gaps appear?
