The Cornell box
3D Render by bisonraviThe Cornell box is a test aimed at determining the accuracy of rendering software by comparing the rendered scene with an actual photograph of the same scene, and has become a commonly used 3D test model. [...] The physical properties of the box are designed to show diffuse interreflection. For example, some light should reflect off the red and green walls and bounce onto the white walls, so parts of the white walls should appear slightly red or green. (Wikipedia - https://en.wikipedia.org/wiki/Cornell_box).

The purpose of this picture is to see how the IRay renderer (implemented inside Daz Studio) can manage a Cornell box. There is only one light in this scene: the square on the ceiling and there is no HDRI for global illumination. That's why the outside of the box is completely black (there is no margin on the picture). Please note how the red and green colors are diffusing on the girl's skin and the shadows.
Rendered in Daz Studio. Enjoy!

It looks like iRay is handling this very well (imho).
Lovely girl and pose by the way!

Wed, Jan 11, 2023Yes, IRay is definitely a great asset for Daz Studio, especially compared to their old renderer (3Delight). Thanks for the comment. Knowing your talent, it's really appreciated!
looks interressting ... i would like to render the same ... what size is the box, what RGB or Hex have you used, and for the same Render i need the Light (Watt) and Lumen. Your render looks a little pixelt ... what is the Reflection index of the walls ... how about the character ... i know characters with a well render skin and others with bad ones ... for that i love the isource like Aino HD ... Thanks for the inspiration and help

Wed, Jan 11, 2023Thanks a lot! Let me try to give you the details you need...
All the scene has been done inside Daz Studio. The box is a perfect cube: 122.62 cm outer wall, 116.98 cm inner wall with a bevel of 0.3 cm on all edges except the inner ones. The bevel can be seen on the front side when zooming the picture.
The cube has all its faces in pure white (RGB=255,255,255), except the red one (RGB=255,0,0) and the green one (RGB=0,255,0). The shader is PBR Specular/Glossiness with no gloss at all (Glossy Layer Weight=0.0, Glossy Color=black). In fact, it's really a basic diffuse coloring with white, red and green colors. Reflection index=1.5 (the default value but there shouldn't be any reflection, just the radiosity effect).
The light is just a square of 35 cm (1 side). It is very close to the ceiling part of the cube with a very tiny shift to avoid collision with the cube. The square has only its down side illuminating the scene. The shader is an IRay emitting shader: emission color= pure white (RGB=255,255,255), temperature = 6000K, luminance = 1500 kcd/m2.
The character is G8 female. The morph is Jessica For Genesis 8 Female (https://www.renderhub.com/usb/jessica-for-genesis-8-female) from USB at RenderHub. The textures are from MDD Danika for G8/V8 Iray Only (https://www.renderosity.com/rr/mod/bcs/mdd-danika-for-g8-v8-iray-only/156610/) from Maddelirium at Renderosity. Hairs are dForce Romantic Curly Hair for Genesis 8 and 8.1 Females (https://www.daz3d.com/dforce-romantic-curly-hair-for-genesis-8-and-81-females) with a simulation.
I know that the picture is grainy... and it's pretty normal considering the lighting conditions for the render. But I really dislike the results of the IRay denoiser which removes a lot of subtle details I like to see. I know I should let the renderer work longer, but I am only working with a laptop and I don't want to burn the cards (it happened to me twice previously on other computers), so I stop the computation after around 30 minutes... And the result looks like a grainy photo taken with an ISO 400 film, so I like it!
