View Full Version : Creating dust and smoke elements in LW w/an eye towards compositing? Tips?

I was following yet another great tutorial (http://www.videocopilot.net/tutorial/procedural_crumble/) by Andrew Cramer on Video COpilot and therein he used a pack of clip art that featured dust/sand falling and other environmental elements.

I'm not going to buy a package just to finish a tutorial, so I created a "dust puff" in LW using particle fx and HVs. (It's a bit rubbish, but worked well enough. "Relative Age" :cursin:, how I h8 you!)

Anyway, just wondered if forum members here had tales and tips about creating dust clouds, smoke, and whatnot as 2D compositional elements. A 'puff' of dust is one thing, but howzabout a 'sand fall' kinda element?

Donīt follow you here, are you talking about real action dust plates, or do you mean cg dust?

For cg dust, turn to turbulenceFD for best realism, If you can not afford it, then extensive work on hvīs and compositing is needed but it will mostly stay behind turbulence realism anyway.

Cheers

If I can't afford clipart, as I implied in the OP, I surely can't afford TFD.

So, the question is: Tips for creating dust and flying dirt elements in all-native (or free) LightWave.

Ahh..then just work on lots..lots of tiny particles(several houndreds or even millions) with hv sprites or pixie dust..render multipass layers and composite...perhaps mix with bigger hv puffs..but doing so will most certainly
get characteristic hv cg look.. where that can be shown in lack of dynamics behavior because you have too fake it with procedural effects...if you are using Large Hv particles that is.

Try and see if you can get any tips from Mr rid...this tree sample with dust is quite nice...

Buy some flour (very cheap), some dark material like velvet (very cheap), get a lamp, get a digital camera that shoots video (borrow one), make swirly dust happen, shoot video. Comp in CG sequence.

Or to fashion a lovely evening gown from. One feels so much more alive when filming floury eddies whilst wearing a quality maxi dress. Frivolous yet fun!

Check into particle illusion :) I believe there is a free version (bought pro ages ago myself) : its a 2d FX generator, and can effortlessly create smoke/clouds etc. Its got really HQ output - even used it in TV spots for Fast n Furious and cusiosly enough American Chopper.

I'm going to have to visit Derbyshire.

Oh yeah, I have that here somewhere.....

Creating dust and smoke elements is always part of a composite Software. It changes to the 3D Software by creating heavy volumetric elements and when Z-Depth is needed.

This volumetric Fog was build in Fusion

Exceptions prove the rule.

How about AE-- how do you create the element in AE?

Fractal Noise ?

HyperVoxels sprite mode are very well to create smoke.

Under After effects look on the side of the Cycore FX / HD.

You can create smoke from an image editor like Photoshop. And you can then use it with the 2 solutions if you want to reduce the render time.

Action Essentials could be nice in compositing or working as animated texture... even a single frame animated in AEE or another soft can do the job if you need clouds

Particle Illusion was used a lot I think for some scenes in Constantine for some hellish fire and smoke..

thereīs also a Particle illusion plugin available for after effects...commercial.

nah... ..

with Particle Illusion v3.0 priced at $400 i'd rather go Turbulence 4D at €400... ($515)

You know what...I think I would do the same ( waving silly with my hand and a soft light voice):)

You would get away with much faster smoke generation with particle illusion and dust etc, but all the thick smoke and dynamic realism in turbulence cant be beaten.

Particle Illusion is of course MUCH faster, and looks DAMN good.

Depends on what style your after and how much dynamics and interaction you are after...simpler dusting, simpler smoke plumes and particle trails, a job for particle illusion, but the full volumetrics and dynamics,explosions for the really
cool stuff is owned by TurbulenceFD.

By the way, there was a plugin for tracking nulls in lightwave for further export to particle illusion, canīt remember where or what it was though.

Why not use the Cycore? They do their job very well if given to trouble :) Everything not requires the top of the range for a convincing result, especially for one-time use. LightWave also copes very well to make smoke.

no good imo, not that convincing... (lack of depth / GI, etc...)

a $30 alternative is Ogo Taiki though... (32bit PC only)

15min VPR render > http://forums.newtek.com/attachment.php?attachmentid=99888&d=1322509387

but that's for $30 "volume" smoke... for "windy" smoke, use stock...
