Particle emitter creating light bursts
on Dec 10, 2010 at 6:04:38 pm

Hi all

I was wondering if anyone could help me

I am trying to recreate this project in Motion

http://www.videocopilot.net/blog/2010/12/light-particles-project/

As you can see, it's originally for After Effects but i am sure the majority, if not all of it, is doable in Motion

the bit that is stumping me is the flash of light that each particle makes as it hits the floor

any ideas on how to achieve that in Motion? i am currently uploading a video of my first attempt and i'll attach the link once it's been hopefully cleared

any help will be much appreciated

EDIT: video of my attempt

HI Tim

Thats a cool clip.

Would a re timing behavior work - if there is such a thing.
I imagine you would need to re time a glow effect to happen as they hit the floor.
But I'm not sure how to target that "point in time if each particle is separate.
It looks like you got closer to the over all effect than I managed.

Hi Tim

As I see it, the biggest challenge in recreating this in Motion is that Motion does not let you make particles of a light.

In the template you link to, the bouncing balls actually light up the floor, revealing the grungy texture.

In order to achieve this I think you would have to make a handful of lights that bounce off a floor, and then duplicate or clone them until you have the desired effect.
It will be time-consuming, but it's not that difficult to do.

First create a floor and the lit-up ball (a feathered circle with a light in the middle will do the trick) then apply a gravity behavior and then an edge collision behavior.

This will make the ball fall to the bottom of the scene and bounce in place.
Add a throw behavior to make the light bounce off to the side.

When you have the timing just right, keyframe the intensity and falloff parameters of the light to give the light burst you need.

Duplicate the ball a handful of times to make different versions of it, and then clone these versions as needed and drag the clones down the timeline at random intevals. you will need to make quite a few clones, so this step will take a while to do.

Finally animate your camera, and upload your movie here, so we can all see your masterpiece.

Wow! That ended up being a long post. Hope it all make sense.

/Anders

Hey, I have been thinkin a lot about remaking the video copilot tutorials for apple motion. I recreated the scene you are talking about for fun and could write up a tutorial on it if you would like. Here it is let me know what you think.

Hi There

Finally rotated back to the land of the living.

Awsome Tutorial - Thanks for that.
It would be nice if there was a way to get the particles flare slightly as they hit the floor. But still a very cool look.

I was wondering where you got all those extra filters from - it appeared as though you have more than I do.

Thanks again

Duane

There are ways to make it "flare" when it hits the floor but thats more manual work for each section.

To be honest i use maybe 1 or 2 of those filters, i have actually deleted most of them. Apples Motion doesn't really have the plug-in community that After Effects has.
