Let me explain you better what my project is about. Its kind of a simple video mapping.
I have a white face mask, hanged on a wall i want to beam to. I am producing the video in after effect, and using particular.
I vectorized, the outline of the mask plus the eyes, resulting in in 3 closed strokes. I am already emiting particles (little dots) from both eyes, through layer emiter option. I aam using a emiter per eye - dots are spreding all over the face.
Now, i determined there would be 2 areas of the mask where i didnt want my particles to go. And this is my problem.
So, i have now 2 issues to resolve.
Tell these (ideally) custom bezier or bitmap shapes, wich right now are circular spherical fields to repel the particles emited.
B)OUTLINE REPELING STROKE
Tell the outline stroke of my mask to repel the particles that — for this, i guess my outline stroke would have to be a Spherical Field itself.
I know Trapcode form, ha 2 spherical fields per emiter, and i can deform the spherical field, producing an elipse or similar.
If theres the need for me to change to form:
- Do i need to re-asign my emiters ?
- con i grab my 2 particular emiters, and connect them to my Form Spherical fields?
Unfortunately, I don't think you can do what you want with Particular or Form.
You may look into Newton [link], a 2D physics simulation system for After Effects.
