i am doing an effect where i need to trace some text with particle world. it will look like the text is being written on by sparkles.
my question is how do i get the producer position x and position y to track along a mask?
i can make a pre comp from my particle world layer and parent it to a null object that tracks along the path but that won't give me the right effect. i need to have the actual producer positions (in particle world) to follow the path.
i'm thinking some kind of expression is needed but my skills are limited.
