Purchase room with lighting?

I purchased a house model thinking I'd be ready to render pretty quickly. Several days later and I'm stunned how incredibly difficult interior lighting at night is in Daz (just getting a well lit room is very awkward). Are there rooms available to purchase which come with full lighting already set up? For instance, how would I know if this one has lights already configured: https://www.daz3d.com/simple-bedroom

    many don't come with lighting, but it looks like the one you posted a link do does because the clay renders shows lights on. The reason I wouldn't purchase that one is that it has an open balcony and they never come with the city scene that use in promos and those are very hard to find

    You can make any object emissive and create light. Just select the surface you want to be a light source, then add the IRAY uber emissive property to it and then adjust the settings

    I've never seen a product explicitly say it had emissive lights or not.

    I will say that the newer a "room" is the better the chances are that it is lit. Also there are several PA's that specialize in environments. They tend to do lights on all of their recent products. Tesla3dCorp and ironman13 have both done environments that work very well, and both tend to have their surfaces broken out so emissives can be added if they're nopt set up already.

    I tend to light my interior scenes and include those emissive lights in the shipped products. So what you see in the Iray promos is what you get when rendered since the emissives are already set up.

    Example the bar scene probably has 50-60 emissives, and its WYSIWYG like the promo when rendered minus character figures of course.

    Just looking through Tesla3dCorp's offerings (not looked at ironman13 yet) and they're very nice, any ideas if the Classy House one is ready to go? Or needs lots of light placing? https://www.daz3d.com/classy-house

    I'm terrible with lighting so I'm using the Classy House which comes fitted with lights: https://www.daz3d.com/classy-house

    The product includes a nice looking interior example render, with a lighting combination of both outdoor sun and indoor lights:image

    My (quickly taken for demonstration purposes) render with the default render settings produces an image which doesn't have the warmth of that interior lightning, nor the shine of the sun:

    From many positions in the house I either seem to get not enough lighting, or too much lighting.

    My question is which render settings would you change to get closer to the example image?

    • Why does my sky have that gray section on the horizon?
    • What would be a suitable time of day to set the sun to?
    • Should I keep Dome & Scene with no environment map to include both sun and interior lights? (my understanding is this setting is neccessary)
    • Is it acceptable to continually play with the exposure until it suits the amount of light in the scene? I thought I'd need to lower the default of 13, but in many rooms it's too bright.

    I can take some screenshots later, but one thing under render settings you are going to want to work with is the exposure settings. A "normally" lit room, a photo shoot setup, a room lit by outside light only, and a bright sunny day are all possible, but those are going to require different exposure settings. If an iray indoor scene doesn't come with a render settings preset (most don't), lowering the default 13 to between 12 and 10.5 (in half step increments) is a good starting place to figure out what you need. Keep in mind, low light situations often take longer to render, and may have more grain in the results even at fairly high completion.

    Which house or room were you starting with in the first post? I don't have either of the two you linked, but if I happen to have the first one I could use that as an example.

    I do not own this so take what i have to say with an appropriately large grain of salt.

    I think the horizon outside is just the way dome and scene looks if you have the right settings. I basically never use that with just the defaults. I use HDRI's which not only give me backgrounds but lighting.

    In order to get a sunlight look, rather than an all over "ambient" light you need to add such to the scene. You can create a bright distant light at the angle you desire or use the Sun&Sky render setting which will let you set the time and day to get a sun position. I tend to use a distant light, since I use HDRI's and that setting doesn't allow them.

    As to the interior lighting, the default light color temp is, IIRC, 6500K which is on the blue side of white and more appropriate for LED's than incandescents. If you want a "warmer" light try changing the color temp to 3000K. 

    To get precisely the renders you desire you're going to have to get into the nitty gritty of emissive shaders and tone settings which can be quite a steep learning curve. Good luck.

    Much appreciated all. So I need an HDRI which is all sky and has lots of light, any suggestions?

     

    Since an HDRI is effectively just an image, how can it give off lighting?

  • Richard HaseltineRichard Haseltine Posts: 102,291

    HDR stands for High Dynamic Range - the images have a lot more variation in colour than a standard photo. They are wrapped around a dome enclosing the scene and each point of that dome is then treated as emitting light of the strength and colour in the image.

    There are many ways to light scenes in DS and it's worth it to learn lighting if you plan to use DS on a continual basis. I would recommend checking tutorials, either free ones on YouTube or paid ones here. Lighting can make or break a scene and add creativity to it with mood changes and although at first it may seem annoying, frustrating and tedious, eventually it can seem fun as you play with various variables...

    There are a ton of lighting products here to purchase which can be daunting too, but just reading the descriptions and looking at promos can even help you learn what various lights do. It's time consuming, I know. I guess it all depends on whether this is just a temporary thing you want to do quickly or something you think you will want to do creatively for quite a while.

    50-60 emissives? Damn, I really do need to get a new system. The last time I tried to render a scene with only about 15 emissive spheres around a square mirror with a character looking into it & having a distant light positioned to shine in through a window. The render was slower than molasses and I was only able to get it to 13% after several hours before having to stop it. I shrunk the resulting render by 50% and it still looks a bit grainy. I guess it didn't help being that the emissives were spheres as opposed to planes. Still, I think my aging system here would revolt if I tried using so many light sources in a scene, redardless of the type. frown 

    I'm guessing also that another one of the mistakes I made in the scene was using too rough of a metal surface for the panels where the primitives were mounted. I probably should've used something like wood and have a much lower reflectivity.

    Curved emissives and mirrors are a bad combo. That's a huge amount of ray tracing to do. There's a hair salon set here with mirrors on every wall. Ittook hours to render on my rig.

    If you don't mind me asking, what kind of Nvidia card do you use? I'm seriously thinking of getting a new system with a Titan RTX once I get back into a proper state of mind.

  • FirstBastionFirstBastion Posts: 7,823

    The big culprits on ray tracing calculations are reflection, refraction and transparancy. The less complex the emitter the better. A 5 sided cube works well shaped like a pyramid with the backface removed so there is no light ray back into the fixture. The glass lens of the fixture will use that simple light in complex ways.

    This render took approx.1 hour, 16 gig,  Geforce 980 4gig card.

    I am still a big fan of https://www.daz3d.com/european-style-apartment. The apartment comes with render ready day and night lights. The environment allows you to adjust the light showing through the windows and each room has a light. For night and day scenes I use https://www.daz3d.com/jm-proper-emissive-lights that have the https://www.daz3d.com/iray-ghost-light-kit-2 material on them. I like using the ring light the best. This allows me to control the light and JM's lights come with an attached camera that makes it easier to point the light at objects. And because it is a ghost light you can place it between the camera and object and it doesn't render in the scene. Also you can try to light the room normally and increase the exposure to 14 or 15 which will then darking the scene without the fire flies and artifacts.

    Sorry to bump this old thread, but the scene is for sale in Fast Grab now.  Does it include the background city scene?
