I’m messing around with the idea of using particles for motion graphics. As a way to create geometry by moving an object through space.
Could anyone tell me?: Is there a way to change the size of the particles that are emitted over time? So, for example, they start small, and stay small, and gradually get bigger. So just to be clear, once a particle is emitted, it should never change size.
Please take a look at the video below. What i’d like would be for the emitted spheres to start on the left very small, and gradually get bigger as the emitter moves to the right of the screen. So the final shape that gets drawn out is a cone.
I tried to achieve this using a texture gradient controlling the particles, and this sort of works, but not really, because the size of each particles still changes over time. Maybe there’s a setting that would fix that, but i can’t find it.
What would be even cooler would be if you could change the size of particles with a lattice. If that’s possible, id love to know how. I tried it and a lattice will effect the position of a particle, but not it’s size.
I’ve also attached the blend file in case anyone is interested in taking a look.
