I am trying to get a nice electrical storm or lightning effect with TS6.6 - any suggestions? It is in an animation, so I really don't want to try and composite it afterwards - rather do it all in TS. |

Hmm, trying to think...
Someone did a Vandergraf (spelling?) generator with sparks and stuff awhile back, can't remember who. |

That would be great if you can remember. I have a cloud using Primaparticles and I want to put a electrical lightning strike within it. I also have a moving camera, so getting it working within TS is a must. |

It was from an old tip on a static image from this page. So I was wrong about the animation part.

TS Tip #11
Note: This tip only only appropriate for TS2 and TS3.
Exploit the procedural marble texture
Do not use this to actually make marble, there are much better marble texture maps out there. Do use this for really cool special effects. Procedural marble makes great skies, lightning, electrical effects, swirling gas balls, nebulas, ad nauseum. I applied this to a sky dome to get the lightning bolt in Excalibur. Here are the settings I used:
Stone R62, G56, B60
Vein R221, G255, B254
Grain Y
Turbulence 10.0
Sharpness 0.89
Scale X 2.0
Scale Y 2.72
Scale Z 2.0

You can use a clipping map with a lightning bolt (light) texture inside.
a self illuminated clipped plane !
Same way you would make led lighted panels....
Have them flash up for just 2-3 frames....

Try Simbiont tS. (http://www.darksim.com/html/simbiontts.html)
Don't forget to grab the Shader repository (http://www.darksim.com/Repository/index.html)
(Electric Rail in the backgrounds section is the one to grab- should be included with the repository)
There's also: EnergyShader (http://etrasti.tripod.com/Products/EnergyShader/index.htm)
(EDIT: Whoops, looks like it's for tS4.3- may or may not work with 6)
As always, a good place to search for 6.6 type stuff is the 'old' forum search page (http://forums.caligari.com/scripts/discuscgi/board-search.cgi)
'Lightning' turned up 67 pages... granted some of them were mis-spelled instances of the word 'lighting', but I quickly found the above links in the first three pages.
Happy Hunting. |

An animated clip map is an animated alpha ........
Pretty simple made in photoshop like this and used together with the function
light material in TS6.6 |

Here you see a light material (material editor light sign)
and an alpha map that changes.... you use about 7-8 of these
and load them into the frames one by one ... that should give
you a nice lightning bolt......
what I done here is just a fast example on a material ball !;)

I cannot remember where I saw it but there was a tut that had an interesting way of doing lightning.
First, model a tree with a narrow trunk. Make a number of, preferably gnarly, branches.
Second, invert the tree into your sky.
Third, set the tree up as transparent and then use an animated texture for your lightning strike.
I will try to search out the tut and post link here. I have not tried this yet but the technique interested me enough to remember it. |

An animated alpha map would definitely be the simplest way to go and lightworks lets you use materials as lights so you should be able to make it emmisive as well.
Here's a static example I did with my gnomish machine WIP:
http://forums1.caligari.com/truespace/showpost.php?p=27838&postcount=26
It's a VRay render using 3 alpha mapped planes and I faked the lighting by using 3 bluish-white point lights. :D One of these years I need to get back to that project and finally finish it.... |
