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.

Thanks so much. I was trying the link on the first page. I'll download when I get home from work.

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.

mCasual

next version will probably have the color gradient option

mCasual

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

mCasual

there ya go, perfect looping 30 frames. 30 billboards
( twas a case of division-by-zero )

------
did you know virtualDub can load animated gifs? now you know

the animated gifs on this page are copyfree

Ivy

wow that incredible.
does it work in daz 4.6?

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

atticanne

I absolutely love these flames. They're great.

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

mCasual

getting there ...

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! :)

mCasual

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)

mCasual

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

mCasual

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

mCasual

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

SimonJM

Wow! Impressive.

i'll do a few tests in DS4.6 ( doing most in DS3 )

and post it today if all goes well :)

mCasual

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

fig 3 smoke'ish

mCasual

tested in Daz Studio 2.3 and 1.8
for people still using their 386sx
kidding kidding, i meant 66MHz 486 beast

mCasual

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

mCasual

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

The new mcjJet 2 with color-ramps lives here :

also a new 360°billboard figure and a new cone-shaped opacity map for the billboards

RAMWolff

This is pretty darned awesome Casual. Thanks so much! :-)

Ruphuss

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
