Is it possible to create a fog alpha reveal effect?

in General Discussion • Other • 4 months ago

Hi everyone,

Im trying to recreate this kind of effect and was hoping that someone could point me in the right direction as its got me a little stumped.

Im have been able to get a 'alpha reveal effect using a specific shape such as an ellipse but not sure how to create the foggy effect.

Any help is greatly appreciated.

Kind regards,

Oli.

If you want actual fog like the fog in that video what I think you need is a particle system my friend. The go-to helper library is Box2D: http://box2d.org/

Maybe post to the forum there?

Also check out this tutorial:

I'm sorry I can't be of more help. I'm just starting out with particle systems myself.
