genie magic lamp smoke?

[stevedeer]

oh!

and it would be nice to use spheres to get my smoke shape then shader them.

any ideas?

there is a thread about smoke in this forum. just search for a thread called smoke and you'll find it. i think you can use spheres with a fresnel shader in the alpha channel and some noise and a bit of luminance in the colour and luminance channel. but it hink it would look best if you emit visible lights (with noise) out of the lamp. then place some particle modifiers, like turbulence and rotation..wind above the emitter to achieve a morre irregular look.
hope that helped you out! :)

here I am so far (as I said just rough, to plan the thing out)...

Not bad! What method did you use?

[stevedeer]

adam

there's about 6 omni lights scaled and positioned, no radiation, no shads, visible and noise (hard noise, lot's of contrast)

It's for a 'sale' catalogue cover, I've got to get the word 'sale' slowly coming out of the spout and getting bigger.

i get all the good stuff ;-)

if it's only for a still and you want the smoke turning into the letters of the word, i would suggest airbrushing it in photoshop. gives you much more controll over the smoke.

if you want to stick with cinema, i would suggest to add a bit of grey to the smoke to give it more structure and more volume

not sure specifically waht type of smoke you want, yours is looking a little billowy I would think it would be more wispy so I soud use sweep nrubs a nickl deformer and some animated noise in the alpha channel to create that growing wipsy like smoke.

i think its pelham design do a free smoke shader if that would help? unfortunately can't fine the link...smokeit i think i was called...not sure about getting it white though. someone else might know the link...otherwise will probably be in plugins section on maxon.net
good luck

[LucentDreams]

Yes smokeIT is great and pretty fast.

seems they recently updated the site, old content new look, hope dreamworks doesn't see the new site ;)

Kaiskai: Cheers...new someone on here would know.:thumbsup:

of course, love the pelham shaders, especially smokeIT. I mean they were my source for fresnel (edge FX cray plugin) before bhodinut released its for free for XL 6. Still use smokeIT myself, prefer it to PC in most cases sinces its easier and faster, but lets be honest PC can do a lot more. for simple needs it is awesome and unlike using visible lights it actually casts shadows

matty2x4 : Ooops sorry bud...

Kaiskai: Probably a basic question....I was playing around with smokeit awhile ago, any ideas why if i say deform/twist a cone with the shader attached i got a stripe down one side....
didn't think its a mapping issue but never had time to take a good look?

[LucentDreams]

depends on which issue, there are two is you place the dafult onto a cone and twist the cone. First you need to increase ray depth a lot to get rid of the black, but you'll see these weird lines still correct? well thats actually due to smoothing cause the twis is twisting the heck out of polygons creating weird twisted shading simply increase the smoothing from 80 to something like 150 and they should be gone.

Kaiskai: you're a star matey...i knew it would be something simple. :applause:
