Annon Posted November 24, 2011 Share Posted November 24, 2011 Well thats subsampling. Ie, It doesn't know where the particle was between the frames. Quick and cheap way is to use a trail sop to mimick subsamples... Quote Link to comment Share on other sites More sharing options...
3dbeing Posted November 25, 2011 Share Posted November 25, 2011 Another option is to run it inline with the pops (rather than baked out geo) and turn up the oversampling... Quote Link to comment Share on other sites More sharing options...
acti Posted November 25, 2011 Author Share Posted November 25, 2011 Hi Christian and 3dbeing, Thanks for your advices,I had baked my particles to bgeo, there are something wrongs when I used trail node and I don't know why.......... there is a quick hip file(my cache file is toooooo big...I can't post them on ........)Thanks again! parEmitFluid_fast.hip Quote Link to comment Share on other sites More sharing options...
3dbeing Posted November 25, 2011 Share Posted November 25, 2011 (edited) Yeah taking a look at it, i think what you want is the pop-solver. I dont have time to do it right now, but see if you can look into it and sort it out using a popsolver rather than sopgeo... ps prolly a better idea to put the popnet in the dopnet rather than outside...

Div Posted November 25, 2011 Share Posted November 25, 2011 Actually to get the subframes you just need to append a timeblend sop to your cached particles, and set the frame range, it will create the inbetween frames for you and that should fix your issue. There is no need here to use trail or do complex stuff in dops. Quote Link to comment Share on other sites More sharing options...

aghourab Posted November 28, 2011 Share Posted November 28, 2011 (edited) Stretch/Blur your source. Sub-stepping is pretty expensive. By blur, I mean trail your source so that the tail covers just over the region of the gap (and the tail perhaps contributes less fuel). Gets rid of gaps with no extra processing costs.
