Volumetric Effects in Daz Studio.

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!

Or... you could just do it the way that stage technicians and magicians have been doing it for nearly two centuries using the "Pepper's Ghost" effect.  If you've been to one of the Disney Haunted Mansions, you've seen this with your own eyes on an epic scale in the ballroom and several other places, and the results are flawless.  All you have to do is put a semi-reflctive plane across the middle of the scene at a diagonal, then place the item to be turned into a ghost off camera at an angle where it's reflection is scene by the the camera, and then add a solid back backdrop behind it so that only that object is reflected.  You can adjust the brilliance of the ghost by adjusting the lights that only shine on it while you can adjust the translucency by changing the reflectiveness of your two way mirror... and doing it in Studio means that you can parent the mirror and ghost to the camera, so you can move through a scene while the figure stays in place.  (Or, you could just do it in post using Photoshop, Gimp or the image software of your choice.)  

 

I do this in animations by rendering two images series, one with and one without the ghost/s then I layer one over the other with a screen blend

I use the bump in the diffuse for a ghost texture on the characters

I've gotten one to load, using it for the fog here just to see how they react to emitters.

This isn't proper volume is just the same as it alwaws since Iray, your just importing geomatry, yet again it another product requied.

Well, you need a way to generate VDBs of course - but there are many options there, and it's no different from needing a modeller for serious content creation. It is, however, a real volumetric effect once you have that.

the following is what I call daz normal

Go to \Shader Presets\Iray\Daz Volume\ The folder Daz Volume dose not exist, the shaders are in anthoer one.

The cube's Default surface will now have a property Volume File. This property dosen't exsit not evan in shader mixer.

That means you didn't install the update "default resources".

All the updates should have shown in DIM.

The dafult plugins were also updated

Install all the upgraded parts.

Start Studio.

Then run the script from the main menu bar "Window>Workspace>Update and Merge Menus"

Now restart Studio.

and have you updated the Default Resoruces?

I find it easier to locate the Effect on the surfaces tab than going the long and dangerous road of the Content Library.

I thought Daz had particle fields already?

I don't know..  I have daz 4.20.0.2 and ubar volume base, ubar volume cloud ect..  I use surface selection on a cube add ubar volume somke the volume setting are there but no Volume file.

Let me guess it's called Simple OpenVBD MDL Smoke I haven't tested it yet but wall yeah I had to go thought the old content menu.

I did this in Daz 3 advance but threre the settings made sense,

This is a quick test of the rabbit vdb file in daz. One is the close up render. Density multiplier is at 100000.0

Paintbox

Whats the memory usage (geo + textures) if I may ask @aneye4art ?

Didn't we have this years ago with Reality?

Jay Versluis

I did a demo on volumetrics this morning, perhaps it helps clairify anythign that's unclear. I'll show off the groudn fog as well as the VDB shader. Enjoy!

No idea, that was LuxRender, this is Iray. Does Reality still exist?

...I think so,  Haven't used it in a long time as ver. 4.x it became rather buggy even the patches were issued (one issue would get fixed and something else would break), and you really needed a fast high core count CPU (like 12 - 16 which were extremely expensive then, like in the multiple 1,000$s) to have a render not take days.    

The three things I liked about it, you could render in background mode. You could close the scene and Daz programme (saving memory resources) after the scene was sent to Lux, and you could stop then resume rendering at a later time. Wish we could do that with Iray without having to purchase Iray Server and have a render farm.

ETA

...so as this has been discussed prior to 02/17 (4.20 relese date) I take it we don't need Daz 4.20 to have have access to this, Just some way to create a VDB.

This is awesome, thank you Jay.

If I remember rightly the creator of Reality, put there software into the Open Source bracket back in 2019..  https://preta3d.com/reality-now-open-source-software/ ; Explains why they went the route they did, Reality was a great program for bridging Luxrender to Daz Studio and Poser..

When I did a search for "volumetrics" every result I got was about some kind of "volumetric diet". I realize the very next thing I click on would have clearly explained what volumetrics is. But it would be nice if that explanation was somewhere near the beginning of the discussion.

Thanks, Jay! :) 

I love how, on the market page, they have this display graphic saying "Volumetrics: Learn More" because, evidently, they didn't have enough characters for "Volumetrics: Click here to literally not learn one signle thing more." ;)

I really hope this is true so we can better make smoke, fire, water, and clouds to list just a few things.

Time to render cloud bunnies :D

I can visualize volumetric with smoke/cloud/fire but can it improve water/slime? The kind of stuff right now people have to do in postwork to look decent.

good thought too, just playing with the new shader right now, but pretty sure it will

yeah, definately! :D nice color on this

Increasing the density multiplier past 1 just makes it even more jagged.

 

i like the voxels :)

btw, you can use a way less detailed mesh, apply the shader, attach the vdb file  exported from cinema, in the dedicated paramenter.

The rpimitive sphere works, but a custome mesh like yours will be more handy.

i made a quick guide on my DA. I will upgrade it, during my testing today.

if you are referring to a render, the quantity of memory used b y the GPU, more stuff (textures objects) more memory load, if the load exceed the memory limit, the render gives an error
