I do have the cozy kitch living room in my library which was released a while ago, and designed for the 3Delight render engine included in Daz Studio. I wanted to render it using Iray.
Shouldn’t be that hard though there is always some work involved. PAs do a lot of the grunt work and tedious work that alllow for one click solutions to bring some of these sets to ready to render readiness.
The Load was easy enough. You get the living room space, and if you get the addon furniture pack, voila, instant cozy living environment with a definite late 60’s – early 70’s feel.
Needed to place a spotlight outside the window to act as sunlight shining into the room. spotlights are easier to aim than distance lights, Since the room set is designed for 3Delight, had to change the window glass material to Uber Iray clear thin glass shader, so it wouldn’t stop the light shining in to the room. I also place a vertical 2m square emissive plane behind the camera, butted right up against the back wall, just out of view of the camera frame. I did try to hide that backwall to give more space for the camera, but unfortunately it was sharing the same material zone as the window wall. Not a big deal, but unfortunate. The emissive was added to provide some ambient light in the room. I could have placed it at the ceiling, but since I intended to have the ceiling in the shot I chose this option instead. The plane provides a very diffused light without pronounced shadows.
The ceiling light fixtures and the wall light fixtures both have a separate material zone for the light bulb which is excellent because we can add a emmisive shader and turn them into proper light emitting bulbs. If we remember from science class, or was it cinematography class, Incandescent bulbs have 3900 color temperature, so I set the interior bulbs to that. And daylight generally has a 6500-7000 color temperature with a slight blue tint, so I added that setting to my emulating “sunlight” spotlight in the color temp channel and the base color channel. I adjust illumination to suit the scene. There’s alot of variable at play with illumination, but suffice to say, you want the scene bright enough to see everything.
As mentioned this is 3DL scene so a couple other adjustments would add to the Iray render experience. Added a nickel uber iray shader to the mirror and cranked the refletivity to 100. I also applied a gold/brassy uber shader to the light fixtures metal parts and the metal frame at the fireplace hearth. Now the carpet is a little tougher. Most uber base shader applications tend to cause the surface to become too shiny. If you reduce the gloss color to a mid tone grey or a midtone of the base color in this case green, and lower the reflective glossiness, it usually mattes thing sufficiently to work. The carpet also need an increase in the bump scale to atleast a 4. I did dull down the fabric on the couches as well.
Okay, Cozy Kitsch Living Room rendered in Iray. My make work project for the day.
