pasto Posted November 5, 2017 Share Posted November 5, 2017 Hello, I am emitting particles from one moving point. I added rotation to this point in order to emit from its orientation. I can just made it turn with a simple $F expression for example. But I am emitting from this point (at a pretty high substep) particles following the orientation I gave to the point before. It gives me some king of trapcode particular auxiliary emission, it works fine but the popnet gets the rotation from the point it emit from once by frame (cooking time) and I need something like 50 cook by frame to get a nice smooth rotation. How can I make Houdini cook more than once by frame on a simple point animation ? I tried the timeblend sop but I am not sure how to set it. To be clear I would need the same 'substepping' effect I get when I make particles spin with a popspin with a 50 substep setting. thanx a lot.

PalTopin Posted November 6, 2017 Share Posted November 6, 2017 Have you tried put the "jitter birth time" at negative instead of positive? That is in the pop source. Quote Link to comment Share on other sites More sharing options...
pasto Posted November 6, 2017 Author Share Posted November 6, 2017 Hello, thanx but that would just redistribute the emission positions right ? I would need to get the rotation information at a larger rate instead. thx a lot. Quote Link to comment Share on other sites More sharing options...
3dome Posted November 6, 2017 Share Posted November 6, 2017 use $FF instead of $F? Quote Link to comment Share on other sites More sharing options...
pasto Posted November 7, 2017 Author Share Posted November 7, 2017 Thx, but it doesn't change anything to the cooking rate I guess. Quote Link to comment Share on other sites More sharing options...
Guest tar Posted November 7, 2017 Share Posted November 7, 2017 you need to show a sample file - pop solvers can be weird. Quote Link to comment Share on other sites More sharing options...
