Night Lighting - Do's and Don'ts requested

Hello All,

Now that I have a few months of using Daz studio under my belt, I would like to try to venture into an area that has caused many problems for me and that is working with lights in night time settings.  Specifically I am looking at both indoor and outdoor settings.   I would like to know the proper way to light objects such as lamps, torches, torchieres, wall sconces, campfires, etc. 

I know how to light a given area using ghost lighting, something I recently learned.  But now I want to show a light source and make that source lit and also light a room or a given area at night with it.

I am on Daz version 4.11 and I do have Terradome3, but I just got it so I don't know my way fully around it.  I do not have a GPU and only use CPU power right now.  I will eventually get a GPU though.

 

Thank you,

Geo

    One way is a bit like Ghost Lights, you apply the Emissive sahder preset to the surface and apply the flame (or whatever, if theer is one) map to the Emission Colour, but unlike a Ghost Light you don't educe the Cutout Opacity. Be aware, however, that doing this with complex geometry will slow rendering as each polygon is treated as a source for light paths, increasing the number of calculations per iteration. You can also use point lights with Render Emitter Off to supplement the light emitting surfaces, though bear in mind that they will still show in reflections of viewed through other surfaces so care is required in placement of the lights and selection of point of view.

    Here's a great tip from TobascoJack on how to prevent blowout when lighting lampshades. It works quite nicely.

    It may or may not be on point to what you want, but I found this thread extremely helpful

    Hello All,

    I am sorry I didn't respond sooner.  I was away for a bit and forgot about these posts.  At any rate I was more after what Richard and Novica were aiming for since those are directly related to light sources.   However, I will look into the shooting day for night thing as that might be helpful in outdoor settings.  I will see though.

    For right now I just want to get lights, torches and candles to look right and make it appear that they are throwing off light.    Most of the lights that come with Iray sets just are set so low, you barely see their own glow!

    Thank you,

    Thank you.  A bit involved, but the results look good.  Worth a shot and hopefully it brings the render times down too. My first attempts at night renders have yeilded unweildy render times.
