I'm doing a project where I need to create a Hollywood-realistic explosion out of the side of a building. I've done some work with particles and HVs before, but for this particular shot I just can't get the level of accuracy I want on the smoke and flames. Hypervoxels are good for a lot of things, but I can't seem to make them do this.

Does anybody have either a good tutorial on how to make realistic smoke and flames with HVs, or a plugin that will do this? I'd be willing to pay money for either.

Thanks!

This plugin works best if you have a Cuda card.
But be aware it currently doesn't work at all in LW2015 on Mac.

You could also do the effect with After Effects and live action elements.

It's not going to be that realist via HVs, way too old tech. Or rather to certain degree you can do stuff but HV fire is just not that cool as modern fluid fire.
Why dont you try Blender, its fire is pretty cool.

Compositing some live action elements would be the other route to go, but it seems tough to find what I was looking for. Shooting something and compositing it in would be a last-ditch effort (and far outside my area of expertise) but it's not out of the question. Hopefully one of these plugins will pan out.

cafefx studio- those guy had a german guy who modeled heads really well write a fire plug in for lightwave that was awesome - i wonder why they never developed it.

ah his name was taron.
=)


are they still doing the group buy for jawset because i would be interested in that.

I second that, and it's not that I want to promote Blender, but since it's free and the rendered output could be composited into your shot, why not try it.

Even better if you can find a way the match your Lightwave scene camera with Blender, I'm sure there's a way to do that.

If you can afford it and justify it...get Turbulence as mentioned.
I reckon you want to do something like this, made by David Ridlen with turbulenceFD and lightwave, I think you can start with content that is provided with turbulenceFD too..

Though it was a bit fun a cool at the time when that came out, and has vorticles (each particle is a force) and had the option to emitt particles based on weight maps, and some other turbulent forces, it needed either hypervoxels or itīs own particle shading system which donīt come close to TurbulenceFD for realistic fire and smoke, and it doesnīt do anything good for explosions either.

For explosions except turbulenceFD, then I would say the long lost dynamite plugin..which was used for the 24 series and the nuke, but it isnīt available any more(officially)

Fire is better with turbulenceFD...

Hi.
I have this LW Preset file...... LW_Voxel_Fire. [Works ok with Lightwave2015].
I aquired it from here......... http://mutinyfx.com/learning.html [LW_Voxel_Fire.zip].
There is a scene/an object/flame plugin files.
The lws, when played, looks very similar to the video demo provided by "prometheus".
and looks almost as good.
I think this is about as good a flame and smoke effect as your going to get out of lightwave.
So give it a look and see if its suitable for your project.
Even if its not suitable for your present project its still a preset/plugin thats well worth having in your folder.
Regards. KEN.

itīs quite good for voxels..but honestly...no way near my clip in my opinion, it doesnīt look almost as good either..
the environment is giving it a wrong illusion too..that the fire has dark smoke, in fact itīs mostly a flame without smoke if you change your backdrop to a mid day color.
Extremly slow to render too compared to fluids.

regardless of what I mentioned in comparison to fluids and my sample of fluids...

The hv sample from mutiny fx...I think it could be better looking actuall with only sprites, the nice thing with volume is the density..but it is also a bad thing since each particle is a spherical radius..thus the impression of blobs always stands out when rendered as a volume, using sprites and you do not have that much of issue with it...it then becomes a little harder to get a good depth shading...but all in all, I think it can be tweaked to look better with only sprites..and it renders much faster as well.
