Hi,
I am fairly new to V-ray and just working on my first interiors.
This scene is a bedroom on a yacht, which has low ceilings, lots of dark wood and 3 small windows (each 60x40cm in a row just out of shot on the right)
Using the physical camera (shutter speed 100 / F-number 8 / ISO 120) and VRay Sun for the natural night, I seem to need a multiplier of around 80 to get the desired amount of natural light in the scene (before any artificial light) and still don’t really get the appearance of the sun beaming in. This value seems high for the sun, but I guess it is because of the small windows.
The only lighting that you see in this rendering is the VRay sun coming through the windows (all spot lights are turned off - you only see the emmissive material)
My main issue is that to achieve a high enough exposure, white or close to white colours like the bed sheets become almost fully clamped out when using colour mapping, and all definition is lost. The burning obviously only gets worse when the artificial lights are turned on.
I assume this is largely due to the highly contrasting colours of the dark wood reflecting little light and the whites reflecting a lot of light.
1. How can I overcome this burning of the white areas, while maintaining a good illumination / exposure?
2. Is it better to have an area light shining through from just outside the windows to achieve a bright sun beam effect?
3. I am using spotlights at a very wide angle for the artificial ceiling lighting (which are turned off in the render below), is it maybe better to use small area lights instead, to imitate the spot lights, so that the light distributes more evenly?
Hoping someone can offer some helpfor the above or any other advise to achieve a better render ;D
Cheers, Jim
