Volumetric Effects in Daz Studio.

I saw that placed on me FB today. Did we discuss this somewhere already and I'm late to the party or is the INCREDIBLE NEWS?

(If I'm late just merge me somewhere lol)

Anyhow, two big questions?

1) Added rendering times?

2) Is this an actual feature that we can turn on/off and have some control over OR a New Product(s) Feature and we will be waiting for vendors to make use of it (for us)?

Downside: Many of the other rendering engines and their associated products use this effect to great effect. Some things that I've used ONLY look good when the rendering engine is running and volumetrics is super-turned up.

    I'm excited

    I'm excited as well!

    So which functions are going to be resrtricted to just PAs? LOL

    Blender can export a particle cache as VDB, I sometimes use them in Octane render 4 Carrara (which will also export Carrara volumetrics as VDB)

    so if DAZ has volumetrics presumably you can create your own in Blender for it.

    well one would hope,

    if they lock it down to PAs well then one would have to use Blender or other programs instead like many do already

    I was mostly being a bit bitter after being burned with the last couple of "feature" releases.

    given the track history not at all unexpected

    Carrara, Blender and Unreal Groom hair works better than their PA only dforce strand ones anyway in my experience  

    and I prefer Carrara and Unreal cheeky

    Carrara could do it 11 years ago and Poser even longer, they are only catching up now

    heck 3Delight does volumetrics and of course so does Bryce

    It IS exciting, but I do guarantee you that it WILL (and probably significantly) add to render times. That's just the nature of volumetrics.

    The version of Iray had been updated to support VDBs but there had been no documented changes for the UI to allow for users to import or configure VDBs.  I hope this isn't a PA only feature or a paid plugin.

    Sounds exciting! I'm very much looking forward to this.

    Version 4.16.1.43 includes a nice atmospheric ground fog, no need for extra volumes.

    Wow... I was just joking a moment ago when I mentioned volumetric effects in DAZ... So that's gonna be a thing now.

    Cool... something else for me to be disappointed about my computer's abilities again.

    I think that'd take my computer about thirty years to render.

    It is exciting though....

    I'm excited for everyone else.

    Is glass going to be a true volume as well? water?

    I've just heard my AMD CPU do a blood-curdling scream. Depending on what's needed to make it work, that is one puddle I (probably) won't be sticking my foot in.

    It's true! They incorporated OpenVDB, made a custom Shader Mixer Shader as described in links provided by Richard and made a Quick Render of a rabbit.

    Volume looks pixelated(voxels) but I assume I missed something.

    I'm really excited for this.  There's no doubt that it will add to render time.  From my own experience, when I've used volumetrics in Blender, my render time took longer (it took more passes to get the image less noisy).  I'd expect the same with Daz.

    Bunny rendered with CPU took 30 seconds, with a NVIDIA GeForce RTX 3080 Ti took 0.028 seconds.

    well Octane and cycles don't take long doing volumetrics

    Carrara native a bit slower

    That's not bad.  I'm curious about render times in a scene with mutliple assets.  I imagine render times will vary depending on what's in the scene.  That's more what I was alluding to (I just didn't explain that very well) when I said I expected longer render times.

    rain, snow, clouds, fog, hail, sleet, fires, smokes, rivers, seas and a lot of other DAZ+ freebie products using those volumetrics are needed now. laughwink

  • HeraHera Posts: 1,958

    Yes! I've been waiting for real volymetrics since I switched from 3DL to Iray. Only reason to sometimes return to 3DL was the volymetric cameras, which were rather easy to use and made good effects. 

  • PerttiAPerttiA Posts: 10,024

    Could volumetrics give us transparent Iray ghost figure, without the inside surfaces on the backside showing?

    No, that's really a Hollywood cheat (if something is partially see-through the inner and back parts will be visible0, but it could fill a figure with vapour as in the bunny above.

    Hollywood cheat? Real ghosts are transparent and Iray is supposed to be photoreal cheeky

  • PaintboxPaintbox Posts: 1,633

    It would be nice of IRAY supported some form of occlusion culling for surfaces away from the camera (per object parameter) for ghost type materials.

  • Oso3DOso3D Posts: 15,040

    The ghost effect (namely, culling backfaces) would be nice, but has nothing to do with volumetrics.

    You CAN make a transparent figure, or a figure made of haze, right now. It's just limited because of the backfaces (particularly the mouth and fingers, where surfaces are really close together)

     

    I'm super excited about improvements in volumetric capabilities in Daz Studio!

  • richardandtracyrichardandtracy Posts: 5,856

    Transparency effects with no back face culling have been available for a wee while https://gal.cdn.renderosity.com/images/image_1287637/file_1287637.jpg (that one is 2006 when I did a silly visual pun called 'Maid of Glass'). 

    Having iRay fog has been good and has been around for a while (4.12?), but I've never thought of making it strong enough to be visible inside a room. Might have to try that. The proper volumetric effect shown with the cloudy rabbit. Oh wow.

    Regards,

    Richard

    Yes, 3DL can do it but not Iray

  • Oso3DOso3D Posts: 15,040

    The big drawback of the haze volumes as they currently are is that the transition through the volume is very linear, and there's always a clear edge. With good composition, lighting, etc you can obscure those edges in a lot of cases, but... it's hard.

    I'm looking forward to volumes with better/feathery/etc edges.

    You can do lots of tricks with Iray, this is a quick render of a Ghost, no postwork, no special shaders.
