View Full Version : Wind River snow FX created in Lightwave

A demo of snow FX I created in Lightwave for the movie Wind River, and one shot from Glass Castle. Just plain ole PFX and sprites. Instances used for the last shot of trees. I tracked most of the shots manually.

Wind River is surprisingly good, and somewhat dark (87% on Rotten). The writer/director also wrote Sicario and Hell or High Water, forming a trilogy of modern anti-westerns.

Excellent Mr.Rid.

Close Enough for Government work!

Refreshing too see amongst all the negatives.

They are all great; but the one where she's driving and the snow is seen through her windshield is mindblowing!
If you hadn't shown us the before and after, I would have been sure that the only way to make that look so flawless would be if the windshield was greenscreened.

Subtle nature effects may not be celebrated as top effects, but darn hard to get right as you really thought that was actually real snow and making believe that it actually was filmed on location as well.

Those are some pretty heavy large volume particle generations, I mean really organic too. Difficult stuff.

Wow congrats, this is ourstanding work!

This is something that should be (if possible due to copyrights) part of the next LW promo video!

Those are some pretty heavy large volume particle generations, I mean really organic too. Difficult stuff.

Yes, each sim took awhile, with up to 8 million particles, but mainly because the most convincingly organic swirl is achieved with an animated texture in a Direction wind, which greatly slows down calculation. I used additional rotating Turbulence and Vortex winds, which normally result in motion that is too procedurally.

I also had to calculate 50 to 100 frames before the first rendered frame to be filled with particles. It helped to separate the fore, mid and background sims, which also allowed more control in comp.

It also helped to erase any unused particles. Using geometry to erase would be most convenient, but particles insisted on passing thru. I had to arrange a bunch of erase boxes instead.

A major Hyper Voxel limitation is that they don't moblur without multiple passes (I used 15 passes, sometimes dithered), increasing render time. I rendered flakes at half rez, and mist at quarter rez (3 passes).

LW's archaic particles and voxels are well overdue for a MAJOR overhaul.

...LW's archaic particles...
hopefully a 3rd party fill fix it soon. or NT.

yes indeed, applying procedural textures in dynamic directional wind is making lw crawl, to bad since that is the way for organic motion with particles,
using procedural textures directly on the emitters particle velocity tab is much much faster..but unfortunately it can not offer the same typ of motion as wind dynamics...
Oldie...3 mil particles, particle velocity vectors driven by prodedural textures, it will however only push particles to form a field, it will not be able to repeat the motion continously in a loop such as wind dynamics.
I can not help but wonder, turbulenceFD particle advection...not possible in lightwave, but in turbulenceFD cinema4d, that may have been useful for at leas making the snow motion work according to more realistic dynamics, then using that to push the particles.

there is a way to "UpRez" particles, haven't used the trick much though...

Awesome work! Very realistic snow fx. Where live I see plenty of snow storms in the winter and this looks very convincing to me.

Simple stuff like this makes me so mad. Lightwave can be so stubborn sometimes.

I regret that I have but two thumbs to rate up for this work. Will you settle for an additional big toe?
Seriously good work, man.

I said this on the old Facey-B... but I always LOVE seeing your work David. Always impressive, and so happy that someone still uses LW in major film work.

Keep it up, and hopefully we'll get a particle overhaul soon! :)

Hi David, just saw the movie In UK, lovely billowing effect you got going on those LW particles, subtly believable.

An honourable thriller to work on. One if , Clint was approaching 50's would not have thought shabby to act Renner.

Great tension through out well worth seeing Wavers.

You've made MY day, David; thanks!

This is priceless for showing students what LW can do. Goes a long way to the thought: just go to work, don't worry about what ain't here. Do great things with what you have.

Very cool work. The snow stuff was excellent as well as the other stuff stumbled upon.
