Teacing Organic Farming and Gardening vi |bout CASFS/ApprenticeshipA TheCente r for Agroecology & Sustainable Food Syste. The latest version of V-Ray for SketchUp is version This sketchup v-ray video presented by MasterTuts will focus on how to resolve the issues found in the.

    In that tutorial he used version 1. Since many new features have been added with the latest version of V-Ray for SketchUp, we have decided to do this mini series of tutorials with the latest versions. In this first tutorial I will be using V-Ray Beta version 1. Here is a screen shot of the particular interior that I will be using. The only difference is instead of using a rectangular light to show the light source, I will be just using a Emissive map. Settings for Material This is the first render. Render 2. Since this is a tutorial, allow me to put 4 spotlights in my four recess lamps. I also use a Emissive map on the light receptacle.

    Position Spotlight Icon Here is the settings for my Spotlight. For me the most critical setting is the Shadow Radius which controls the softness of the shadows, Shadow Subdivision controls the smoothness of the shadow and last but not the least is the Penumbra Angle.

    In the image below I used 0. Spotlight Settings Here is the render using Spotlight. In this render I used a very low resolution.

    This is the reason why I have splotches and grains. This can be corrected easily by using higher Subdivisions and Samplings. Render Using Spotlight 3. Lampshades Here is a simple lamp I modeled in SketchUp. I will show you how to place V-Ray rectangular lights. V-Ray rectangular 1 and 2 run along the height of the shade.

    The one that casts shadows is the third V-Ray rectangular light. This one casts shadows, double sided but I made it invisible. Apply Material to Layer. To access the texture editor.

    How to add mapping: Click ok. Select the desired texture mapping ex. V-Ray for SketchUp Version 1. You can setup options from anti-aliasing and Environment to camera and resolution.

    Open V-Ray Option: Allows you to open the pre-saved V-Ray options. Load Default V-Ray Option: Allows you to revert back the settings to the V-Ray default options. Controls all the rendering parameters in V-Ray.

    Save V-Ray Option: Allows you to save all of the V-Ray parameters to use in the future. Anti-aliasing Adaptive Subdivision: This new option improves the anti-aliasing around the edges of the geometry and on vertical and horizontal lines.

    Object Outline: Randomize Sampler: This option displaces the sampler slightly to get better anti-aliasing on horizontal and vertical lines. Your edges will always be sharp using Object Outline. Physical Camera On. Physical Camera Use the Physical Camera to render any type of standard camera.

    Using a Spherical Camera. With this new feature you have the ability to create different lens effects. Sun and Sky Sky Brightness: Allows you to setup a different intensity for the sky mapping without affecting the intensity of the sunlight.

    When editing the sun parameters on GI Color. With this option you can get a clear sky or a dark sky with a moon. This shading method will add more realism to your render and can produce the feeling of a more detailed image.

    Determines the amount of area where the AO effect is produced. The amount of Ambient Occlusion. Large values mean better quality. Determines the quality of Ambient Occlusion. This option enables or disables Ambient Occlusion. This image has no AO.

    Note how the details on the door and windows are missing. Larger numbers mean more Ambient Occlusion. In the image on the left. Now you can control the range of color.

    V-Ray will proceed with its calculation as though color mapping is applied. If you want to create an AO pass for post-processing purposes. Here is another example of Ambient Occlusion. Adaptation Only: The color mapping will not be applied with this option.

    Clamp Level: Allows you to define the level at which color components will be clamped. On the environment. Color Mapping We added two new options in this version. The image on the right has AO.

    Lower values mean more noisy results. If Bias is too high. Photon Subdivs: File picker: Allows you to load the IES file that defines the light distribution. Larger values cut away more from the light. The light option defines whether such portions of the material will be lit or not. Shadow Subdivs: This value controls the number of samples V-Ray takes to compute lighting the quality of the shadows.

    Filter Color: This parameter determines the color of the light. This can be useful in scenes with many lights. If the Bias value is too low. Caustic Subdivs: This option controls the amount of photons that V-Ray will trace to estimate caustics quality of the caustics.

    Determines the intensity of the light in lumens. The icon is located in the V-Ray main toolbar. Area Speculars: When this option is Off. If the Bias value is too extreme in either direction. For such surfaces. Large numbers slow down the calculation of the caustics photon map and may take more memory. Parameters Enabled: Turns on or off the IES lights.

    Turns on or off the IES shadows. Higher values produce smoother results but take more time. Note that the actual number of samples also depends on the DMC Sampler settings. Cutoff Threshold: This parameter specifies a threshold for the light intensity. Bumped Below Surface: This is used for cases where the light shines on surfaces with extreme bump mapping.

    Shadow Color: Determines the color of the shadows.

    Illuminating Engineering Society. A typical W electric bulb emits about lumens of light. Shadow Bias: Bias moves the shadow toward or away from the shadow-casting object or objects. Soft Shadow: This causes the light to take into account the information about the light shape in the IES file if there is any shape defined so that it produces proper soft shadows. Affect Diffuse: This determines whether the light is affecting the diffuse properties of the materials.

    Affect Specular: This determines whether the light is affecting the specular of the materials. If you specify 0. Remember the lower part of the cone is the light emitter.

    You can hide this part on the ceiling This is the area that emits light.

    Do not hide this part on the ceiling. Click on the scene to select the location of the IES light. At this point you can adjust the setting of the IES light to get your desired effect. Right click on the IES light. How to use IES Lights: The physical camera will control the exposure of the sun and also reduce the brightness of every other type of light. For example. Do not close that part inside of the other surface because you can hide the IES light.

    For this reason when you are using the physical camera you might use a very high value. Once you created an IES light you have to scale the icon to your desired position.

    Render your scene. When this setting is used. Visible light surface power measured in watts per square meter per steradian. Lumious Power lm: Total emitted visible light power measured in lumens. Large numbers slow down the calculation of the caustics photon map and may use more memory. Keep in mind that this is not the same as the electric power consumed by a light bulb.

    When using this setting. Turn on or off the spotlight shadows. A typical W light bulb only emits between 2 and 3 watts of visible light.

    The different units are: Default scalar: The color and multiplier directly determine the visible color of the light without any conversion. Radiant Power W: Total emitted visible light power measured in watts. Area Specular: When this option is Off the particular light will be rendered as a point light in the specular reflections.

    Determines the intensity of the light. The light surface will appear with the given color in the final image when seen directly by the camera assuming there is no color mapping involved.

    Spotlight Spotlight: This is a new V-Ray for SketchUp light type that can be used to create a spotlight. Intensity Color: Sampling Falloff Type: Determines how the light will transition from full strength to no lighting inside the light cone. Enable Controls On: Turns on or off the spotlight. Allows choosing the light units. Visible light surface power measured in lumens per square meter per steradian. The icon is located in the main V-Ray toolbar.

    Cone Angle: Allows you to adjust the angle of a light cone. Penumbra Angle 0. Please see the example below. Cone Angle 0. Please see the examples below. This is the radius of the light source. Inverse Square Decay: Still an inverse relationship. The intensity will not decay with distance. This is the physically correct decay mode. Shadows Shadow Color: Barn Door On: This option enables or disables the barn door effect. If you increase this value you can create softer shadows.

    Inverse Decay: An inverse relationship between the intensity of the light and the distance it travels. This is the kind of light that the barn door effect tries to mimic. Barn doors restrict the light cone on the four sides of the light to produce a rectangular light shape in the real world. Barn Door Right: Allows you to control the right shutter value. Barn Door Top: Allows you to control the top shutter value.

    Barn Door Left: Allows you to control the left shutter value. Barn Door Bottom: Allows you to control the bottom shutter value. The possible types are: No Decay at all. If you are using the Physical Camera you might have to increase the power to make the light visible.

    This is the area that emits light. Click on the icon to add a V-Ray Spotlight into your scene. Click on the scene to select the location of the light. How to use Spotlights: It is the middle of the base area. At this point you can adjust the setting of the Spotlight to get the desired effect.

    Right click on the Spotlight. You can hide this part on the ceiling. How to use the VFB Channel:
