What is turbidity in V-Ray sun?

Turbidity – Determines the amount of dust in the air and affects the color of the sun and sky. Smaller values produce a clear and blue sky and sun as you get in the country, while larger values make them yellow and orange as, for example, in a big city.

How do you adjust sunlight in V-Ray?

The V-Ray sun is tied to the SketchUp shadows and sun. So go to “View” then to “Toolbars” and turn on the Shadows toolbar. Once you do that, you can see it appears in the top right-hand corner. Zoom in and turn your shadows on by clicking the shadow icon in the shadows toolbar.

What is shadow bias in V-Ray sun?

Shadow bias – moves the shadow toward or away from the shadow-casting object (or objects). If the bias value is too low, shadows can “leak” through places they shouldn’t, produce moire patterns or making out-of-place dark areas on meshes. If bias is too high, shadows can “detach” from an object.

What is V-Ray lighting?

The VRayLight is a V-Ray specific light source object that can be used to create physically accurate area lights of different shapes. Shapes are selected through options when creating the light via 3ds Max’s Create panel (or Create menu), or, after the light is created, through the 3ds Max Modify panel.

What is V-Ray physical camera?

The VRayPhysicalCamera uses real-world camera settings such as f-stop, focal length, and shutter speed to set up the virtual CG camera. It also makes it easier to use light sources with real-world illumination, such as VRayLight with physical units or VRaySun and VRaySky.

How do I make my V-Ray light invisible?

The “Invisible” checkbox affects on the visibility of the light in the camera only. You need to turn the “Affect reflections” checkbox off.

Why is my V-Ray render so dark?

Rendering > Render Setup > Effects > Photographic exposure settings may be turned On or are set inappropriately for the scene’s render engine and/or lighting setup. Gamma correction may be turned Off in the 3ds Max preferences, resulting in dark-appearing test renders.

What is VRAY lighting?

Where is the sun direction?

east
The Sun always rises in the east. It doesn’t matter if you live in the Northern Hemisphere or the Southern Hemisphere. We see the Sun move across the sky based on the rotation of the Earth. Since both the Northern and Southern Hemispheres rotate in together, the position of the sun is the same in both hemispheres.

What is VRAY for SketchUp?

V-Ray® for SketchUp is a 3D rendering software that combines real-time and photoreal rendering — all in SketchUp. From beginner to pro, Chaos® V-Ray has all the tools you need to visualize your SketchUp projects from start to finish.

How is the intensity of a V Ray Sun controlled?

In this case the intensity of the light does not depend on the V-Ray Sun’s position in the sky and is controlled through the intensity multiplier. override – Sets the color of the V-Ray Sun to match the color in the Filter Color parameter but the intensity of the light still depends on the V-Ray Sun’s position in the sky.

What are the parameters of vraysun and vraysky?

Enabled: on, Turbidity: 2.0, Shadow subdivision: 36, Intensity multiplier: 0.01, Size multiplier: 10.0. Size multiplier – this parameter controls the visible size of the sun. This affects the appearance of the sun disc as seen by the camera and reflections, as well as the blurriness of the sun shadows.

How does blend angle and turbidity affect vraysky?

Blend angle – Controls the size of the gradient formed by VRaySky between the horizon and the actual sky. Horizon offset – Offsets the horizon from the default position (the absolute horizon). Turbidity – Determines the amount of dust in the air and affects the color of the sun and sky.

How to set the color of a V-Ray Sun?

Override – Sets the color of V-Ray sun to the color in the Filter Color parameter. The intensity of the light still depends on the position of V-Ray Sun in the sky. Intensity Multiplier – Affects the brightness of the sun and can be used to reduce the default brightness.
