Foam effect WITHOUT round/bubble shape

[Tudor “ted” jelescu]

What plugin/particle system are you using (there’s quite a few options)?
Can you post a sample image?

Could we see a screenshot or two to know what you’re talking about? It would be useful to see your comp window to see the problem you’re describing and it would be useful to see the effect settings window.

If you’re using the Foam effect, your particles should be whatever shape you specify.

Hi!

Could you please tell me how to go about specifying the shape of the bubble within the Foam effect? I can’t seem to figure it out

Thank you so much!!

You are probably doing it right (the shape you reference in the layer list has to have an alpha otherwise it will be a square) but you have to turn on “Render” at the top of the plug in settings instead of the default “Draft” otherwise it will always look like blue circles.

You can of coarse do this in Particular with much more control.
In particular its best to use a sprite or a textured polygon for the shape of the particle (you choose what alpha’d layer you want to be the sprite – it has to be in the time line – by choosing Sprite as particle type in Particle settings and then choosing the source layer in the Texture/Layer setting a few rows down – not from the Sprite options – unless you want one of the Sprite shapes) .
To get a layer in AE to emit particles that are the same color as where those particles came from choose Layer as the emitter type and then choose the layer in the time line you want to emit from.
Make sure to set the Random seed to larger than (much larger even) than the 100,000 default settings or you will start to see looping patterns in the “random” look of the particles.
