I'm no pro in Daz but do I intensify the environment or the sun disk/glow intensity? I tweaked Outdoor INT 250 and rendered an all-black screen. Color Warm 3 kinda worked but it doesnt lit up the enclosed room nor the crisp mahogany cabinet as the original scene.
To adjust the light intensity you can do either of the following:
- Render Settings \ Environment Intensity (higher = brighter)
- Render Settings \ Shutter Speed (lower = brighter)
You don't really want a sun disk as you need to have light hitting the window from many directions (hence HDRI). A sun dusk is more of a spotlight / distant light rather than HDRI. Not familiar with Outdoor INT 250, however the HDRI in the following location should work ok.
My Daz 3D Library \ Light Presets \ Iray HDR Outdoor Enironments \ DTHDR-SunsetA - Believe it comes as part of Daz4+
If you aren't happy with the amount of light inside you can always create an emissive sphere with a temperature of around 4500K to get yellow light. Method of how to create your own "ghost light" is within my tutorial thread (see sig).
