Here i was creating a foam effect in After effects. After several problems which occurred, this way was the successful one
The foam effect is created by inserting an image by dragging it into After effects. The next step is to create a new solid and click “make comp size”. We then go to the effect menu and click on “Simulation” and then the “Foam effect” which we are trying to create. On the image we have inserted, we will see a red circle in the centre. We then click on the eyeball and turn off the layer with the image so that the focus could be on the effect itself. The red circle is where the effect is simulated from. If we move the time indicator at the bottom, we will see the foam effect in place. In order to edit and customise the size of the foam and its randomness for example, we need to scroll down a bit in time so we could see the effect. On the left hand side of the page, there is a “view option” which allows us to to change it to “rendered” view so we could see what it would like in the end. Under the “view” option, there is a “producer” option which allows us to control the red circle in the centre. The various options we have are “Producer orientation”, “Producer point” etc. The next option is “Bubbles” which allows us to change the size of the bubble itself, the “size variance” so we have a combination of sizes and the “strength” in which it develops. Also, under “rendering” we could chose the texture of the bubble. The various options to chose from are “Water beads”, “Soda water” and “bubble wrap”. after we chose the texture, we then click “user define” which allows us to chose a picture which the effect will take place over. To do this, we click the bubble texture layer and click the image we inserted at the start and when we scroll through the timeline, we will see the effect taking place using the image.
