I have a grease pencil object with animation keyframes. An animation of a simple 'star' which wobbles and flickers now and then. The animation is designed to loop well.
Here's what I'd like to achieve:
Scatter many instances/copies (>100) of the GP object in my scene, without having to place each one manually. And randomly vary the scale of each instance.
Have each instance automatically face the camera at all times ('billboards').
Have each instance play back its looping animation with a random time offset, so create the illusion that these are independent objects.
So far, I've tried:
Adding a track constraint on the 'master' grease pencil object which got it to face the camera at all times. And then using a mesh as an emitter which would generate instances of the GP object as particles. This approach satisfied criteria 1 and 2, but not 3 since I found no way to add a random time offset to each particle's playback.
Any ideas very welcome!
I thought I'd found a way to achieve 3: by specifying start and end frame range for the particle system both below 0. But it turns out that particles' current frame always seems to match the source objects current frame. So I'm not getting the time offset variation I'm hoping for.
