jacob clark 6 Posted September 28, 2013 Hey Jeff, This is great info for a commonly faced problem in Houdini. Any chance of these solutions, or information making it into the package? Also, we've had great luck varying Disturbance by the speed of the Simulation. Actually Sam Hancock figured that one out. Really saved us on some prevous shows! -j Share this post Link to post Share on other sites
Guest tar Posted September 28, 2013 Awesome info; If Jeff had a 'tip' jar I bet he would be very rich Share this post Link to post Share on other sites
Solitude 150 Posted September 30, 2013 Great infos. I'd really love to see this kind of info put into the docs with some example images showing the differences (as well as sim time differences) between some of the techniques too. Share this post Link to post Share on other sites
Diego A Grimaldi 84 Posted October 1, 2013 Damn Jeff, such a good read! Thanks Share this post Link to post Share on other sites
Nicholas Yiallouris 2 Posted May 21, 2014 Thanks for the valuable info ! One question, how would one "set the density field as both your Threshold Field to control the cut-off threshold for the disturbance" Not sure of the syntax to read a field in. Thanks Share this post Link to post Share on other sites
rayman 447 Posted October 29, 2015 (edited) I'll just leave this one here. Very easy and controllable way to add details to the simulation, that I wanted to try for such a long time. Cheers!

rayman 447 Posted November 1, 2015 (edited) I sent you a message on vimeo, but I'm posting it here too if anyone has the same issue : Hi, thats because you are bringing another object to simulation, and Gas Field Wrangle is not pointing to specific object data to update velocity but is using "*" instead.To make it work find "set_vel_from_particles" node and go to Inputs Tab. There is a field called Input2 DOP Data, which points to "*/`chs("../createpoints/datapath")`". Change "*" with the name of your smoke object, for example "smokeobject1/`chs("../createpoints/datapath")`" and it should work as you expect.Cheers! Edit: you may also try $OBJNAME/`chs("../createpoints/datapath")` if you don't want to change the name of the data each time when object name changes.
