particular -custom movie particle qn
Hey guys,
In trapcode particular, I have a selected a custom particle from a comp- a triangle shape as a 3D layer, set to constant rotation using the time*x expression. I would like to know, how can I randomize the playback position of the particles so that they aren’t all rotating the same. Also, if any advise can be given to make the rotation slow down or stop entirely would be good. I want to create a burst/explosion-like effects with triangles so that I have varying sizes and rotations of the ‘shrapnel’. Random sizes is easy of course but I would like to know whether I can randomize the starting playback position of the animating comp so as to give it the impression that they all have their own individual rotation.
Any suggestions are welcome, would really like to get this effect going for a uni project. Without it I’m nothing 🙁
Thanks in advance, Eugene

From Particulars manual (which you can find by presssing the “options” link inside particular then pressing the “help” button inside options:
****
The Split Clip modes splits the custom layer into a number of clips given by the parameter “Number of Clips”. For example, if the custom layer is 30 frames and “Number of Clips” is set to three, that means it will be split into three 10 frame clips. This is useful for creating a set of animated particles.Split Clip – Play Once Randomly select one of the clips and play the clip once.
Split Clip – Loop Randomly select one of the clips and play the clip looping.
Split Clip – Stretch Randomly select one of the clips and time-stretch it to fit the particle life.****
So if you have a clip 150 frames long divided as follows: 1st a triangle going slow for 50 frames then another triangle rotating medium for 50 frames then a third triangle rotating fast for 50 frames then choose “split clip loop” and then set “# of clips” to 3 — Particular will emit three different triangles each rotating three different speeds — more triangles — more # of clips and you can have 20 different speeds if you like (I think?)
Does this help??

To start the particles at random times in the animation, then just twirl down the ‘particle’ menu and then twirl down ‘custom’… in here you’ll see ‘time sampling’ – select the option you want from this drop down box i.e. “random – loop”.
Hope this helps.

Cheers Simon! That’s precisely what I wanted to do. Now my little test is working just how I imagined. Also thanks to Jim, not exactly what I was going for but I’ve learned something new at least. I’m sure it’ll come in handy in the future.
Thanks guys, Eugene
