marcoF Posted October 4, 2018 Share Posted October 4, 2018 Hello everybody. I am new to this Forum and wanna say hi to everybody, i was following a lot of things going on here already since some time and now its time for my first question I have following setup. I am advecting parallel copied lines by a volume (pyro) to get the lines moving like smoke. When the lines get advected they get stretched (points move away from each other) every frame until they get really low res on the top of the advection spot. My idea was to resample the lines every frame and put the resampled output back into the pop network. Logically i would do that with a solver. The problem is the solver lets my system dissappear. Is a pop network inside a sop solver not working and only working with geometry or do i do anything wrong? Would be awesome if somebody would know what i can do. Cheers, Marco Quote Link to comment Share on other sites More sharing options...
kfu Posted October 4, 2018 Share Posted October 4, 2018 You can always do the pop sim first and then copy line to points later on, or if you want line swim around like smooth noodles, maybe do particle trails. Another way is do sop solver inside dop net, hope it's helps Any hip file? Quote Link to comment Share on other sites More sharing options...
marcoF Posted October 4, 2018 Author Share Posted October 4, 2018 i cannot do the pop sim first cause i need new resampling every framestep. else the polylines get stretched out and lowpoly-looking. i will try the sop solver inside dop net. thx for the tip Quote Link to comment Share on other sites More sharing options...
anim Posted October 5, 2018 Share Posted October 5, 2018 - use sop solver inside of popnet instead - or alternatively use VDB Advect Points inside of your sop solver to do the advection instead of popnet Quote Link to comment Share on other sites More sharing options...
Andrea Posted October 5, 2018 Share Posted October 5, 2018 Hi, try give a look to the file. What I did was to resampling the line every frame in a sop solver inside the Pop network. Just it gets messy really quickly, probably the smoke needs to be less turbolent advect_and_resample_lines.hip Quote Link to comment Share on other sites More sharing options...
marcoF Posted October 8, 2018 Author Share Posted October 8, 2018 Hello anim and Andrea, i will test the sop solver inside pop network like you suggested tomorrow when im back on my workstation. Thanks a lot for the tips and the hip file in the meanwhile. Cheers, Marco Quote Link to comment Share on other sites More sharing options...
marcoF Posted October 19, 2018 Author Share Posted October 19, 2018 The sop inside the dop network did exactly what i needed. Thx a lot for helping me out. Awesome Quote Link to comment Share on other sites More sharing options...
