View Full Version : Transition from logo to particles
08-31-2008, 08:24 PM
I have all my particles on my logo but what i would like is a smooth tranistion as the logo is being blowing away by the wind.
Any tutorials that could help me?

You'd best do that in comp. Render both passes (geometry and particles) and mask the geometry/particles out as needed in comp.

ok this probably will not help too much, but i did manage to dig deep and find this one:
Texture based particle emission
"you can tell the particles to emit for only 1 frame and the animate a wind blowing the image shaped particles off into the sky..."
Its very very old but may get you started in the right direction.

There are a couple different ways that you could do it.
First, if your particles are already birthed on your Logo, then you could move a deflector through them and that would send them to a different event which would have the controls for where they went. I tried that attempt first and didn't really like the results.
The second way to do it, and the way that I found I liked the best, is to use a bitmap to control where the particles are spawned from on the logo and also to control the disappearance of the logo. First, I created an animated gradient that wiped across some text. This Gradient controlled the opacity of the text causing it to disappear.
Next, I modified this gradient to just be a thin strip to tell the particles where they should birth from.
Note that the left hand side is the same on both images so that they match up and so the particles start appearing slightly before the text fully fades out.
Then you just put in your controls for wind, gravity, etc. and there you have it.
Here's some stills of a test animation.
Hope that helps.
