Notice how changes in this parameter affect both the visible sun size and the shadow softness however overall illumination strength remains the same. This example demonstrates the looks achieved with several different color mapping modes. Higher values cause the color mapping mode to change.
The Ozone parameter affects only the color of the light emitted by the sun. Notice how larger values cause the sun and the sky to become yellowish while smaller values make the sky clear. Generally, this controls the amount of dust particles in the air. This parameter's effect is visible when photons are used in the GI solutions or caustics. This area is represented by the green cylinder around the Sun's ray vector. Other effects from extreme values include moire patterns, out-of-place dark areas on surfaces, and shadows not appearing at all in the rendering.įor more information, see The Shadow Bias example below. If this value is too extreme, shadows can "leak" through places they shouldn't or "detach" from an object. Higher values move the shadow toward the object s while lower values move it away. For more information, see The Shadow Subdivs Parameter example below. More subdivs produce area shadows with better quality but render slower. In this case the intensity of the light does not depend on the V-Ray Suns position in the sky and is controlled through the intensity multiplier. This affects the appearance of the sun disc as seen by the camera and reflections, as well as the blurriness of the sun shadows.įor more information, see The Size Multiplier Parameter example below. For more information, see The Intensity Multiplier Parameter example below. See the Notes section for more information. VRAY INTERIOR LIGHTING TUTORIAL – Rendering with Daylight in SketchUp! Since the sun is very bright by default, you can use this parameter to reduce its effect.
Android clear app data programmaticallyįor more information, see The Ozone Value example below. Smaller values make the sunlight more yellow, larger values make it blue. For more information, see The Turbidity Parameter example below. 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. The multiplier controls the suns contribution to specular reflections. FIXING VRAY GLASS TRANSPARENCY in SketchUp - Vray 3.6 for SketchUp Tutorial This is useful to prevent bright speckles on glossy surfaces where a ray with low probability hits the extremely bright sun disk. Note how in addition to the scene brightness, the sun position also changes the appearance of the sky and the sun light color. This example demonstrates the effect of the sun direction. The V-Ray Sun and Sky are based largely on the model presented in.
