In this tutorial, we are going to learn how to use an image and vex to control our particles. we are going to use an image to control the movement of our particles, and to do that, we are going to use the brightness of each pixel to control the direction of our particles.
We need to know the position of each particle and extract the color of the corresponding pixel. That will be done with a simple vop node with a color map. then, we are going to use the brightness from that color and convert it to direction or velocity.
Hope you enjoy this video and learn with us!
