    It's from the link in the first post that one gets the page 404.
    THANK YOU! Looking forward to playing with this one.
    I have noticed with interest this phrase ... I might borrow it sometime ;-)
    To avoid incomprehensible effects ...

    welcome !

    thanks i corrected the link ( which was merged with the word "so" )

    np, Works now.

    important update and fixes

    the DS1/DS2 versions had become non-functional

    fixed

    it still worked for DS3.0 and DS4

    but not for DS3.1

    actually it didnt work well anymore with DS 3.0 and DS4, the emission didnt happen at the position of the emitter

    but now it does !

    you can make great particle effects with it

    tip: to increase the smoke/particle flow, create your particle animation at a frame rate like 150fps
    then set the FPS back to its normal rate, like 30 fps
    and you get a 5X flow

    for this 30 frames animation ( which could be directly used in video compositing , take it )

    loaded a 60-billboards figure

    i created a vertically standing cylinder

    set the timeline's FPS to 120 FPS
    the playrange from 0 to 120

    selected the cylinder

    launched mcjJet

    adjusted the settings as you see below

    it's the [Default Settings] but a narrower spread, 5 degrees and the end of simulation is at frame 120

    ran the script

    changed the frame rate back to 30 fps

    X-Scaled the hole billboard figure for a narrower jet

    changed the opacity maps for all the panels to the one shown in fig 3 ( take one! : ))

    Oh, what fun. Thank you very much. I'll play with this when I take a break from my programming class.

    next version will probably have the color gradient option

    sodium flame color gradient, software render
    ( next version of mcjJet )

    both the ambient and the diffuse color of each "particle" are animated

    but there's still a small looping quirk to fix

    fig 3, a 30 frames, 30 panels animation with precise looping .... almost

    it's supposed to work in 4.6 yes, but the color-ramp effects are not included

    they should be soon

    there's all sorts of issues to fix, like the rotations of the billboards, which strive to always face the camera

    today i should fix the billboard/panel orientation issue and post the new version with the color-ramps/gradients

    the panels always face the camera which is good, but they always stand up, this was good for billboard-trees but not for rocket flames

    i didn't remember it but mcjJet already supported 3 types of billboard face-the-camera options

    Doncha just hate it when you can't remember how cunning you have been! :)

    the new mcjJet will have improved billboards-face-the-camera processing

    sometimes when the camera was moving in relation with the planes, they did strange flips

    I like your steampunkettes video
    looks like you are using a lot of scripts there
    and .. you really have your own style...I like that
    though I am not Bob (or God)

    there will be a color-ramp selector for the ambient color

    and one for the diffuse color

    maybe one for the opacity (fade out ) effect which is presently directly proportional to the "age" of each emitted particle

    and using your own color ramp will be as easy as saving a 32x256 pixels jpeg image in mcjJet's "colorRamps" folder

    tomorrow i publish the new mcjJet with color ramps, i just want to make it a bit more fool proof

    ah i think i understand now ....
    seen from Amy's point of view
    the billboards are narrow vertical strips of light,
    that's why they don't illuminate her much

    i'll try cone-shaped particles

    -----
    fig 2 : using a 4-panels-per-particle figure

    Blender-Cycles is not really suited for scenes with concentrated light sources

    if you scale the billboard figure before computing the particles animation, you can get stroke/line shaped particles

    DS 4.6 tests underway !
    and i fixed the offset function, which was used to move the emission point at the top of the cone

    fig 2 - UI resizing because pixmap.resize crops instead or resizing

    mcjJet 2 is now on the net !

    tomorrow i'll update the manual

    https://sites.google.com/site/mcasualsdazscripts/mcjjet

    i decided to leave the old mcjJet be
    and added mcjJet 2

    in case there's backward compatibility issues or something

    one important point to note is that the script comes with a subfolder containing some color ramps

    you can create your own as long as they are in jpg format and are 256 pixel wide

    https://sites.google.com/site/mcasualsdazscripts/mcjjet

    oops i now see the thumbnail for the ds1 version is 800x800 :) don't think it will cause problems

    mcjJet 2 update !!

    while writing the manual, i discovered the burst mode's final fade-out phase was not there anymore

    so if you downloaded mcjJet2 last night or this morning, better re-download it

    https://sites.google.com/site/mcasualsdazscripts/mcjjet

    also note that mcjJet2 will soon have its own web page / manual

    and it will be at https://sites.google.com/site/mcasualsdazscripts4/mcjjet2

    thanks for your nice tool

    both links give a 404 response

    for complicated and richer effects search the Daz3d.com store for the word "particles"
    http://www.daz3d.com/i.x/search/searchsub/?_m=d&sstring=particle

    and the vendor "Nerd3D"

    hello casual
    would it be hard to make a script for "ctr-d" for an animated range ?
    I always do this frame by frame and that's not fun
