Does anyone know of an already made ring light or circle light rig for studio?

I was actually thinking something like this

Hm, ok.

Do you own/use any modeling software like Hexagon or Blender? Such a ring should be easy to model. Then, in DAZ Studio, you simply have to apply the UberAreaLight to it.

Or you try to be creative with the built in DAZ Studio content. One thing that comes to my mind is to load the AreaLight Disc and place a sphere in the center, which covers the light in the center and therefore gives you a ring of light.

I don’t have DS on this workstation but doesn’t DS have a torus primitive?  Can the torus be set to be a light emitter?

Yes, there is a torus. But the problem with it is that it would distribute the light in all directions if you apply a UberAreaLight on it. But you do not want that if you are going to create a light ring.

It’s pretty trivial to select a ring of polys on one side in the Geometry Editor and assign a ‘Light Ring’ surface to the selected polys.  Then invert the selection, name it ‘Backing’ or something.  Then go into the Tool Settings panel, select the surface named ‘Default’ and right click and remove it.

Now you have a torus with a light ring surface (still needs a UAL assigned to it) and a backing surface.  I imagine a little more work to parent it to a camera, and you’d have a combination camera and light ring.

This.

That’s exactly how I did mine, except I used a disc (a cylinder with a Y dimension set near-zero) for my gobo (“go between”, anything that blocks light) instead of a sphere in the center, and I then added a grid made up of a whole bunch of rectangles perpendicular to the plane of the discs. Just remember that the camera has to be slightly forward of the gobo.

I actually imitated my entire set of standard photographic studio lights using nothing but DAZ Studio primitives or insanely simple Carrara models.

In DAZ Studio you can make a ring light, real soft boxes (8 reflective panels, 2 diffusers) with grids (30 long thin rectangles in one direction, 40 in the other), strip lights, and honeycombs (bunch of rectangles at 60 degree angles instead of 90 degree).

I used something that could lathe a line (Carrara, but it’s a snap in Hexagon or Blender) to make a beauty light, a snoot for a hair light, an umbrella, an octabank, and a big parabolic.

Greetings,
By the way, thanks for this.  I decided to proof-of-concept it, and built a torus, selected some polys, set up surfaces, assigned a UAL, parented it to a camera so the camera pointed through the middle, and futzed with DoF and such, and it’s working GREAT for closeups!

Probably the first viable light I’ve ever constructed for myself. smile

Very good. But now you have to construct new eyes, or at least alter the material settings on the ones you have now. Specular color white, try about 30% strength, and strip the texture map.

Yeah, I fought with those eyes for a painfully long while…  It’s the ‘Eye Surface’ in Legacy, or ‘Eye Reflection’ in the ‘Surfaces’ view.

The key problem seems to be the existing reflection is done in the opacity map.  So I can’t drop the opacity to zero, or…well, there’s nothing to reflect the light.  I can’t put it to 100% because then it’s pure white over the eye.  So I have no real idea how to use the Eye Reflection surface. :(

I need it to be transparent, but still reflect light and/or have specular, etc….  I’ve got no idea how to do that.  Maybe uberSurface?

I’m a little confused, how does one apply and uber light to a surface?

Just like any shader, select object and its surface and apply.

InaneGlory has what I think you are looking for in one of his sets, his background I believe is in photography so he aims for that sort of lighting in his sets. Look at his Photostudio sets. Photostudio 3 has a ringlight and a beauty dish.

Has he moved his store to another site?  I just checked his store here at DAZ, and it’s empty.

Only if Fast Grab and several other categories have suddenly been dropped.  I think the store software is having a bit of meltdown or some other issue.
