Amelia S Posted May 25, 2016 Share Posted May 25, 2016 I'm rendering an interior view. When I first rendered it, there were nice shadows cast through the windows from my heliodon. Later I went in and introduced a few lights to the scene. I lost the beautiful shadows, and when I delete the lights, the shadows are there but very subtle. I think I remember reading something about renderworks detecting light sources and adjusting to them, but cannot find the thread. Any ideas how I can revert to the original lighting? I haven't changed the heliodon. The background is a physical sky (also not changed). Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted May 25, 2016 Vectorworks, Inc Employee Share Posted May 25, 2016 Perhaps Ambient Lighting turned back on? It will sometimes wash out renderings and make shadows less obvious, it can be changed in either the Renderworks Style, or under View > Set Lighting Options if you arent using a style.

Amelia S Posted May 25, 2016 Author Share Posted May 25, 2016 You're right, Jim! Thanks. So here's the follow-up: Is there a way to make the room brighter without upping the ambient lighting? There are 4 windows and a pair of french doors, so I know this room would get pretty bright in real life with just the sun. Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted May 25, 2016 Vectorworks, Inc Employee Share Posted May 25, 2016 Two main ways: 1) Probably the easiest, select the Heliodon and up its "Sun Brightness" value. You can set it higher than 100%. This is basically a multiplier on the default light that the Heliodon emits, generally you don't want to crank it to something like 500% but often 150 or 200 is useful. 2) If you create a viewport with a Renderworks Camera, you can increase the cameras Exposure setting to artificially increase the amount of light that appears in the final rendering.

Vectorworks, Inc Employee PVA - Admin Posted May 25, 2016 Vectorworks, Inc Employee Share Posted May 25, 2016 You could also increase the number of indirect lighting bounces, but while this might look good it is extremely expensive render-time wise and generally the above two options I mentioned will work better without affecting render speed dramatically.

Amelia S Posted May 25, 2016 Author Share Posted May 25, 2016 Great! I got the shadows back and they look good. My white walls (where in shadow) are a bit blue, so my first instinct is to try to change the emitter temperature? Quote Link to comment

Jonathan Pickup Posted May 26, 2016 Share Posted May 26, 2016 if shadow areas are blue, look at the background rendering colour Quote Link to comment
Amelia S Posted May 26, 2016 Author Share Posted May 26, 2016 Thanks Jonathan! I have a physical sky background that I don't want to change, but changing the Environment Reflections seemed to do the trick! Quote Link to comment

zoomer Posted May 26, 2016 Share Posted May 26, 2016 I always like the difference between bluish sky color and warner sunlight. It gives a lot of depth. It is just that VW and C4D look quiet yellowish by default. I finally realized the right direction to set color temperature in Render Settings. Decreasing temperature to lower values will make look the rendering colder or more blueish (or more natural). I always went to 6500 K daylight, which makes everything worse of course. So in your case, too cold colors, you can increase the color temperature. Quote Link to comment
