Particular 2.2 stepping problem
on Jan 9, 2013 at 12:30:05 am

Hello,

we are having problems with a particular setup which involves a layer grid emitter that is showing a stepping problem when the emitter has some animated rotation parameters. We googled the symptom and found that it is because the rotation parameters don't have any subframe stepping. We already tried the 99fps composition idea to make the stepping disappear, but it just makes the steps smaller but still very much visible.

I attached a picture of our problem to see what we are trying to achieve

Is there any other approach or solution to get the desired energy band ? Any ideas to solve this or do it in a different way or approach?

Thank so much for the help.

Best,

Martin

One way to deal with this problem is to basically stretch out your particle footage to something very large like 10x your footage in a precomp and then put it on top of your bg and then retime it to the correct length. For example, if your clip is 4 seconds long, precomp your particular layer and emitter layer. Change the comp settings from 4 seconds to 120 seconds. Stretch out your keyframes using alt and drag to retime them. Adjust your particular settings to get a smooth super line. This comp will be super slomo. Next, back in your main comp, the particular precomp should be on top of your bg footage. Simply choose, Layer, Time, Time stretch and set the percentage to 5 percent. Now, you have tricked Particular into subframe sampling. It would be better if you had more control of this inside of Particular, but this way will work. If it is still stepped, simply increase the time of the precomp until it is smooth and then adjust the timing accordingly in your main comp.
