The “new” particles from repopulate are created at the exact same points in space frame-to-frame. This is causing some bad temporal moire patterning for us, because the particles appear to be fixed in space. Could we get an option to randomize the positions?
Obviously we want to repopulate to such a density that we don’t see the individual points, but as grid isn’t frustrum aligned, it’s not always practical for particles that are nearer to the camera.
I could expose a random seed parameter (currently the seed is not user defined). You could seed based on frame number. That way points from frame-to-frame would have completely different positions within the repopulation volume. It would result in a static-y random effect. Is that what you are looking for?
Yes, we’ll allow the user to define the actual seed, we just need to be able to specify. Thank you.
Ok, I’ll add that in there. No problemo.
Hi Chad, the latest build has a random seed parameter for repopulation. Thanks for the suggestion.
