There is nothing wrong with buying light sets.  I used to buy lots of different light sets. And while I can make my own now, I still buy some.

The images you have linked to are volumetric lights. Advanced stuff.  But here is a tutorial on how to create it:

I used the tutorial to make the lights in this image, but I spent time playing with the dials.

the first one linked above appears to be a lite cone, but it's lacking 3D shadows, which are not intuitive nor easy to describe but you know them when you see them, and which are computationally intensive and probably not easy to achieve in poser yet, but are standard in other renderers.

does seem to be abit of work and study this light stuff lol. ill have to mess around and see what i can get

Volumetric lighting does add considerably to the render time and a dark background to bring out the lighting.

It's not a particularly good example, but it shows you don't need to buy lightsets at all. Everything you need is already there in Poser.

But to be honest, I first learnt these things using Saintfox's Fiat Lux lightset, which I can recommend. You get lots of nice light and atmosphere set ups to play with, and you can start with one of those, learn what the various settings do, and adjust to suit your subject.

Shall I describe the basic setup for an image like this, or are you happy to go play by yourself?  :O)

Before I go nuts for nothing and tear your head off (joking of course) please explain what you meant here about "probably not easy to achieve in poser yet". We all know Poser has shadows (3 kinds) and they are all 3-dimensional, which is what 3D stands for. So I'm really confused and you must be talking about something I'd like to know about that Poser is unable to do easily.

You must be talking about something else than simple shadows, because Izi just demonstrated how great this works in Poser, and if you know what settings to use it takes 30 seconds to set up. I call that easy.

I agree the first image is terrible - why is the crease in her thigh lit up and why is there no shadow under the body? Wierd. All 3D apps can do better than that, even DS and Poser.

I think what Miss Nancy is trying to describe is volumetric shadows.  I'd expect to see them underneath her - they are there but not very distinct

it's all in the atmosphere settings :)
I can't remember the exact settings because I don't render in Poser these days - in Vue they are turned on by default

Miss Nancy, the volumetric shadow is what you can see (the darker areas between the spheres and their ground shadows) both in my image and in yours. That isn't flat shadow on the backdrop or the ground, since the spheres are not shadowing those areas. It's shadow on the volume.

IsaoShi, okay, how exactly did you set that up? I was trying to do something similar and it didn't turn out.

A backdrop or background object is essential for the volume to show up against. I should have set the backdrop further back to prevent the spotlight beam falling on it, but that's just where it happened to be in my laboratory! Don't set it too far back... this will just increase the render time unnecessarily: in the atmosphere node you choose the distance between volume samples along each raytrace, and this sampling continues beyond the spotlight beam until the raytrace hits the backdrop.

Coming up in a bit... settings for the spotlight and atmosphere node.

Quote - This is interesting... just been playing around with a point light and atmosphere.
The point light has bagginsbill's inverse square falloff shader, which is why the volume intensity is so high near the light.

I didn't get an email update on this thread, so sorry I didn't reply.

Miss Nancy, as others have said the volumetric shadows show up automatically when you do as Izi showed. There's nothing to set up - it just happens.

Izi - that is incredible. It had not occured to me that the ISF light would do that glow. It's f'ing perfect!

I also see the nice volumetric shadow behind the robot. Beautiful work. This is gallery worthy. If you haven't posted it, you should.

Incredible image.  Now where did I put that bookmark for the inverse square falloff shader? Damn.

I hate to seem like a pest, Isao, but how did you set up that one? I followed your posted setting up above and for the first time actually got Atmosphere to work for me! I love that second image you posted.

@Latexluv: Glad you got it working! You don't seem like a pest, I'm happy to help - goodness knows I get enough out of these forums myself.

(Btw thanks to bb for his complimentary words. I've posted a much improved image 'Curiosity' in my gallery, together with a little conversation between me and Zlata which might hopefully entertain).

That last image was just done with a single point light instead of the overhead spotlight. However, it's not an ordinary Poser point light. It has a special shader inside it that gives a physically correct Inverse Square Falloff (ISF) of intensity with distance from the source. This shader gives a very high (in theory, infinite) intensity at the light source.

I adapted this ISF shader for my own use. I'll post the shader setup I used in the image in a few minutes.

You have to plug in the XYZ location of the point light for the shader to work properly. With the XYZ values as Parmatic parameters, I can just copy them across on the Parameters palette after positioning the light.

You also have to specify the distance from the light at which the intensity is the level chosen on the Intensity dial. Again, I have this set up as a Parmatic parameter dial.

Thanks so much! I have BB's Inverse Square in my material folder but I wasn't getting with it what you were and now I can see why. Thanks so much for explaining it!
