Hello,
I have having trouble with a particle effect and I can't find anything on how I would achieve it. I have a rough idea of how it might work but my houdini knowledge and experience isn't good enough to actually do it.
I am trying to create the effect of an illuminated object flying through a room full of particles, like dust in a warehouse. I want the particles to initially be invisible and only when the target object passes by for the particles to become visible and then begin to glow. So far I have a set up where the target object flys through the scene and collides with the particles. As it does this I have an Attribute transfer that gives me a field of influence that I want to drive the visibility of the particles. Does anyone now how I could do this?
