Help about volumetric lights in Daz3D

[dick bullcock]

Hi!

How can I make volumetric lights on Daz3D?

I am trying to use volumetric lights with Daz3D, and I feel a bit lose. I have not find a good way to make them.
I google it, and found a pair of tutorials, but they were totally out of time.
I have tried a bunch of assets. Epic Props- Godrays & Volumetric Light for Iray looked like really nice: The video and the help pdf are awful, and the rendering time is incredible huge. The results are not bad, but they are not good.
The other assets that I have tried are .....no words.

I tried to export the scene to another motor, but it takes a not practical time. It is a shame, cause with other programs, to use a volumetric light supposes to make 3-4 clicks, but I have not found the way to do it with Daz!

Any help will be welcome.

Have a nice day!

I don't think Daz Studio actually supports volumetric lights. I could be wrong, but the approach that the products you reference take (sticking in carefully-designed translucent planes) seems to be the only way to approximate the effect. Not sure if it's a limitation of iRay or 3Delight, or whether the Daz3d folks just decided not to bother.

Thanks for your quick answer Rich , what you say is just what I fell about.
It is a shame, cause with other programs it is just an option.
Thanks!

Thanks a lot no__name . This is one of the tutorials I tried and it is fine, but I don't get the effect I wish. I will see the video just now, it is more clear. Thanks a lot!

I remember doing a foggy cimetery by night with that with more or less success. Problem it's that is rather render intensive and didn't find a way to really 'crank' it. Ended up using more transparents planes like Rich say, just to save time.

If we are talking about some kind of foggy environment (and not about god rays), you could experiment with the Matte Fog Settings in the Iray Render Environment Settings. This one took only minutes:

I was just about to post the exact same thing, matte fog was introduced in the latest release version so not many people know about it. It's under environment in render settings. Interestingly it doesn't increase render time but reduces it.
To bad I can't use that Daz version for developement

Thanks for the answers.
I am just looking for this:

I mean, light has "body", you see the volume it occupies, volumetric lights.
It makes its lightning function (it can be a fake) but in a fog/dusty/etc environment, it cast the shadows in the ambient.
It is like the god rays that you mention, DonJoe , making the cutout of the silhouettes.
The example is from Cinema. Actually in more of the serious 3d programs you have the "volume" option in the lights that can support it.

Imo, problem with Matte Fog is that it's not a scattering volume but basically just a filter that applies to the whole render. It has zero 'weight', it can't cast ray or particular density in X area and it's rather cheap to render because it doesn't affect light bounce. It also makes its use quite limited tbh, if you could apply some kind of gradient mask instead of just on/off, it could be cool tho .

I was thinking that they use some cheap trick like usual there, it wouldn't render faster otherwise, but I haven't had the time to fully test it since I don't have the newest Daz version on my render machine.

It has a parameter called Matte Fog Visibility which kind of controls the distance where the effect kicks in:

First one is 25m, second one is 10m:

it is nice, but they are giant steps!!!
Anyway, it is a good solution for fog simulating

Ah! That's not what I have in mind
Let's say the fog start strong from ground, decline for 1m, and completely disapear further. Kinda like give the fog a linear pattern (could be great). But I'm not sure it's even technically possible with matte fog tbh , some people may know better.

I doubt it, it seems kinda flat, but let's see what plans nvidia has with it, at least they seem creative.

Close enough.



I attached the duf file in the post.
Change SSS amount of the cube for adjusting 'density' :
