LW Particles octane

[Sinelab01]

Hi is there a way to render hypervoxels in octane, I have a rocket and would like use octane but it will need particles for smoke or is there work around for this ?

Currently you can't render volumetrics with Octane. You can use a LW instancer in particle mode to instance objects, for example spheres, with some kind of specular or translucent material, but not real volumetrics yet.

Ok thanks for the quick response

Just for further clarification on this topic -

Is rendering volumetrics like LW does, but with Octane, actually possible?
Therefore is it a feature that 'will come' in the future, or something we will never see happen?

Thanks, and for all your development efforts,
Dom

At some point, Octane could support volumetric rendering, not in this 2.x dev cycle as far I know, but perhaps in the future. So yes, render volumetrics in Octane could happen in the future

Ok I see.

So it's not a limitation with the LW Octane plugin but rather Octane itself does not do volumetrics ... as yet.... Maybe some day it will.

I found the best alternative is to run your particle simulation, then instance flat geometry with a UV. Place a transparency map and texture to that geometry. The results can be pretty good. I've simulated smoke this was with very convincing results.

Nice, can you please post a image or video to see the final effect?

Sure!

Sorry for the super low res render, these only took 5 seconds a frame.

I originally developed this to use for semi-static clouds and tornado's. The producer ended up using some quick/cheap stock footage so I scrapped it.

I could have used more "textured squares", this one only has one. And I could have animated the texture and brought it in as a sequence, but i didn't.

If I end up working on this technique more i'll post my findings in this thread.

I simplified it a bit. The shadows get weird at certain angles, but I think I know a way to fix that.

Oh, and sorry for the grain, I kept the render times short.
