Not too sure on the Geometry Shell but to get double sided but you could use two area light panels back to back. wink Yeah it does look as though it is just a rectangle and nothing else and not even a surface based light either. I never get much from his documentation, a pet peeve of mine so at this stage I am not sure about needing it.

I don’t think that’s just a pet peeve of yours, I heard a lot of people complain about the omnifreaker documentation. Your guide is so much more informative & detailed, I may have missed key features of the area light without it. Thanks again.

Yeah I think I can skip the omArea. Just get the Spot & Point lights, maybe look into the hair and soft lights. Probably wait for a sale since I’m so far behind on mastering everything I already own.

I would say get the spots and points when you can. They realy are excellent products. But I would hold off on the others until you learn more. I wish I had learnt more before buying a lot of products.

It does make me happy seeing others getting something out of these tutorials I make. It seems more and more people want me to finish an Uber Surface tut I said I would do. I wish I could but with this computer I am finding it hard going and there is a lot to cover. I have every intention of doing it it’s just a matter of when I can get a new PC.

Yeah I bought way too much stuff too fast, feel like I may never use it all, trying to stay away from the Genesis 2 stuff.  Any tutorial from you would be great but I though UberSurface is less illusive than some of omnifreakers other products.  I also think the new subsurface shaders replace it for a lot of things but I do need more practice with UberSurface for the anisotropic and stuff. I think it may be better with metal and hair, etc.

I saw your dA journal, that sucks your PC died.  I really struggle with my PC that is over 5 years old.  Makes it hard to do multiple figures or detailed landscapes.  Decimator helps a little.  Sounds like you might have it rougher than me though.  I can’t wait to get a new one as soon as I can afford it.  I wish you luck as well.

Thanks yeah for a while I was only working with one 2GB RAM module as the other slot went bye bye then the motherboard went pop. Now I have a realy old 2GB machine that I am borrowing. But at least I can still make images with this one using DS3A and 4.6 for small stuff.

I agree that the new SSS shader base does the job of Uber Surface and probably better. I say probably as I can’t test as 4.6 will crash when using the shader but from what I have seen and read it does a better job. Also yes I agree the Uber Surface will be good for hair, metal and glass. And funny you should mention metal as I have a render cooking in DS3A now, using Uber Surface for metal using Anisotropic on Stonemason Mech 2012 Enforcer and lit with two area light discs and UE2. The render has been going for 24 hours now and only at 69%. But I am using UE2 set to IDL with stupid high quality settings and raytraced reflections so I am not surprised. Looks good though, well I think so. smile I will be posting it tomorrow. In fact every surface in the scene has Uber Surface applied.

As for SSS info the PDF that comes with the new SSS shader is absolutly great for the info contained, so I will probably gloss over that part of Uber Surafce SSS functions.

Yeah the subsurface documentation is excellent and helped me to understand shaders better in general.  Also learned a lot from the following forum threads which you were also a part of:

http://www.daz3d.com/forums/viewthread/22952/

Look forward to seeing your render.

LOL Yeah I am still learning but recently with help from others here and on DA I had gotten it all straight in my head just as the new SSS shader base came out, and with me asking questions I gained a better insight. Which came out when I did my last two monster renders using Uber Surface 1. I just went in set up the channels and rendered a test, tweaked a little bits and I was done very quickly. Same thing with this render that is cooking. one day setting up the scene and materails, for me that is super fast. I normally spend two weeks or more on one image.

I got a PM today asking about Specular highlights when using Area Lighting.

The nature of both Area and Environment lighting in Daz Studio is that both are called Diffuse Light which by their nature being surface based lights is that the Specular highlights will always be weaker than using a Distant, Spot or Point light. So if you are using Area or Enviroment lighting and you want stronger highlights then adding a further light/s like Distants or Spots set to Specular light only will help in that regard.

So, are you telling me that the reason default UE lights (including the neon light) turn all the models in my scene into silhouettes is because the normals on everything is inverted?!  Why is this?  And why wouldn’t Omnifreaker have fixed this from the getgo?

Also, do I have to flip the normals on every object in my scene, or just the object emitting the light?  This is really hard to understand.

Not sure how you came to these conclusions. The flipping normals I refered to was when using a default Daz Studio Spehere Primative as a light source in which it has the normals facing outward at defualt. So if you wnated the light to go inward then the normals would need flipping.

All Area Light presets have correct normals. All Daz Studio content have the normals the right way.

You only have to flip normals for a an object that is being used as a light source and this is only the maker of the said object didn’t flip them from the get go. Again not common from DAZ3D store products.

As for the Uber Area Light Neon Preset (not UE) what exactly did you do. Take a deep breathe, chill and take me through the process.

As you can see below it is working in DS4.6.

I had read about the normals thing in other topics as well.  It was my understanding that this was what they were saying, though admittedly I found it pretty confusing..

I loaded an object, then loaded the neon light.  That’s literally all I did.  The light glows, but any object in the scene is black.

The neon light is subtle by default, it will not light up the entire scene.  It only lights up things a little bit that are very close to it.  You can increase the neon light intensity so that it lights up a lot more or add additional lights to the scene. You also will probably want to increase the neon light samples to reduce noise.

Well the info I provide is complete so it will be down to what you did. As Swawa3D said above it all depends on where you placed the object and where you placed the Neon Light.

Szark - the issues with phantom lights showing in mirrors, that you solved by setting opacity to zero is maybe something to add here too.
