loudsubs Posted October 24, 2011 Share Posted October 24, 2011 Hi, Im using a pyro solver to make a dust effect and I want to control the smoke's vortex confinement using its temperature. Basically I want the smoke to initially have a lot of swirl (when its hot), then fade off as it cools off. Im not sure if Im setting this up correctly, right now I have a shelf made billowy smoke setup. I have an apply data node under my pyro solver with a gas ramp plugged into that. destination field: confinement source: temperature Should the gas ramp be plugged into the pyro solver? Where does the diffusion stage fit in with the velocity and advection stages? Anyone have advice on this DOPs goodness? Thanks Quote Link to comment Share on other sites More sharing options...
old school Posted October 31, 2011 Share Posted October 31, 2011 If you want to adjust any of the fields in the solver, you should use one of three green inputs in to the Pyro Solver DOP. The Left green input is for velocity adjustment prior to any advection, the middle green input is for advected fields and the right input is for modifying any of the results. If you wire your gas ramp in to the right most green input, it should work. You can also use the Gas Field VOP to reshape any fields to your liking. Have a look at the attached file where the temperature field is modifying the confinement field using VOPs inside a Gas Field VOP. Note: If you open up the details view and inspect all the fields on a smoke object that is being modified by a Pyro/Smoke solver, you can read and write to any of these fields inside the Gas Field VOP. Just make sure to match name and type correctly (float vs vector). confinement_driven_by_temperature.hip Quote Link to comment Share on other sites More sharing options...
old school Posted October 31, 2011 Share Posted October 31, 2011 Oh I also unlocked the Smoke Object and it's Smoke Configure Object DOP to add a Scalar Field Visualization DOP to view the confinement field in the viewport. It is the green smoke you see in the viepwort when you open up the file. Quote Link to comment Share on other sites More sharing options...
loudsubs Posted November 1, 2011 Author Share Posted November 1, 2011 (edited) Thanks, the gasfieldVOP is very useful and flexible. Definately gives me a different perspective on how I can work with fields. Thanks for the info. Edited November 1, 2011 by Loudsubs Quote Link to comment Share on other sites More sharing options...
