Re-render the same view and note that the lighting is more diffuse and a background sky is now simulated.Д©.В Conintining with the V-Ray Asset Editor, now create a neutral gray Generic material, name it вЂњmaterial_1вЂќ. Now turn on the вЂњGI BackgroundвЂќ, вЂњReflectionвЂќ and вЂњRefractionвЂќ options, and using the same methodology as above, add the same simulated Sky to each of these вЂњEnvironmental OverridesвЂќ.ДЁ. The right-most triangle controls the cutoff value for the maximum color вЂњwhiteвЂќ.Д§. The left-most triangle controls the cutoff value for the minimum color вЂњblackвЂќ. That is adjust the upward poining triangles below the color histogram. Select the icon in the lower left-hand corner of the V-Ray frame buffer window and use the вЂњLevelsвЂќ option in the V-Ray frame buffer in the expanded dialag box to adjust light balance. The initial result will appear to be overexposed.Д¦. You may wish select вЂњHosek et alвЂќ in the dialog box and then change over to вЂњPreetham et.

Note that the default вЂSky modelвЂќ is вЂњHosek at alвЂќ, a particular simulation method, and one of three options available. Switch the Sun from вЂњ/Rhino Document SunвЂќ to вЂњ/Sun LightвЂќ (the V-Ray sun) and set the вЂњTurbityвЂќ (i.e, quality the air) to 2.0. The dialog box on the right-hand side will change as in the following image.Д¤. Select the symbol wih horizontal lines on the right-hand size and choose the вЂњskyвЂќ option from options that appear to the upper left of the dialog box. An expanded dialog box that opens to the right. Within the V-Ray Asset Editor, go to the вЂњEnvironmentвЂќ tab, turn on the GI Skylight option by selecting the checked-box (see checked-box in the screen capture below), and then also select the blue and black checker-box icon to the right of the checked-box. Note that the вЂњsunвЂќ symbol is visible as an 3D arrow in the foreground of the вЂњPerspectiveвЂќ view window below.Дў. With the mouse cursor placed with the left-mouse button in the command prompt area, select the return key or right mouse button to place the sun light symbol at the origin of the x-y plane.В Adjust the perspective view similar to an eye-level camera position and horizon line as shown in the вЂњPerspectiveвЂќ view window below. Select OK in the dialog box above and then at the Rhino command prompt note that the default location of вЂњPosition вЂќ is indicated. Within the вЂњSun Angle CalculatorвЂќ, set the Sun Options to вЂњOnвЂќ, and determine the time and day of the year, as well as set the location either by picking a city (e.g., Richmond, VA) or entering the exact latitude and longitude.ДЄlternatively, as we did in the workshop, select the вЂњManual ControlвЂќ method and used the simpler dialog box as shown below to adjust the azimuth and altitude more directly. Next, go to the вЂњV-Ray LightsвЂќ panel and select sun control icon to open вЂњSun Angle CalculatorвЂќ. Go to non-V-Ray Rhino Render Tab, and toggle off the standard Rhino вЂњsunвЂќ symbol. Within Rhino, go to the menu item вЂњRender>Current Renderer>V-Ray for RhinoвЂќ to ensure that V-Ray is active. The вЂњsunlightвЂќ layer will be used to place a V-Ray sun.
