Is there a simple fireworks tutorial around somewhere? I don't actually need the particle part as much as the surfacing. I've tried surfacing the particles with hypervoxels but I can't find a way to make them glow. They just look like dots moving around.

Could try using partigons, then add glow to the surface that's tied to the partigons.

if you use hypervoxels sprites, you only need to set a good setup for it, and if you want additional glow, use external video editors like after effects and add glow there.
Alternativly use particle partigon emitter instead, those will be affected by lightwaves image glow processing, hypervoxels will not.
if you already have setup your fireworks with an hv emitter, you can use the hidden command .particle2partigon, to find it..use edit menu and search for it, drag it on to wherever you need it in your menu.

and if your lost...do a youtube search...

Mr Rid has some good descriptions in the text.

Thanks I actually went to YouTube first but my search Included the word tutorial, maybe I should've left that out. dwburman has a nice one about the particles but it looks like he never got around to making Part 2.

Edit: It's funny, I came across this one and while I don't care for the actual result of the tutorial, it looks blurry to me, I really do like the animation he uses for the open and close of the video. That's just the effect that I'm looking for, I just need to do it in 3D so it could go around another object.

If you're talking about the sparkling/twinkling effect, I usually do this by giving my particles varying life spans (Particle life +/-) and using a gradient set to Relative Particle age in whatever texture setting you're using to control the visibility or brightness of the particle. The gradient has a few sharp spikes throughout it so each particle will flash a few times over its life span. Make sure your particles do have life span or this won't work. Setting the particle life to '0' makes them live forever.


I think David Ridlen mentioned using a noisy channel modifier on an envelope/curve ( the [E] button next to the numeric input field) to do the same thing.
See Prometheus' quote below.

Talking about the glow: There's the Bloom and Corona Image Filters (ctrl+F8 for the Processing panel) that add glow post render based on image brightness. You'll want to add Flare2Alpha as well if you're going to be rendering this with an alpha channel. It's probably better to do these kinds of glows in a compositing app if you have one.

a tip if you want star glow, you could map pre rendered lensflares that uses starfilter, and map to hv clips.

I also think dponīt has a sort of image process filter for certain glows, maybe not useful for fireworks? Havenīt tested but it might work.

That's probably what I was thinking of. :D Disregard my noisy channel comment.
