Hi, I have a earth and three small spheres are flying around it (orbiting). They are emitters for particles. These particles should feel like a sparkeling tail. Unfortunatly they are only born at precise frame time. But they should be born in the time between the frames, too. This way, they tail looks like a broken car exhaust ;-) How can I manipulate the source, so that a smooth tail appears? Example image here:
If you are birthing those particles from very fast moving geometry you need to add a timeblend sop to the geometry input. Then you can create sub frame data for the particles. You can check it all works by looking a the animation globals and turning off the integer frame option.
Additionally, on your popnet try and increase oversampling. I also find that it helps if you divide the total emitted particles by the oversampling. That way the clumping that you describe is reduced as well.
Anotheer thing to try would be to use part of your particles and shift them by some fraction of a frame.
