You may wish select “Hosek et al” in the dialog box and then change over to “Preetham et. Note that the default ‘Sky model” is “Hosek at al”, a particular simulation method, and one of three options available. Switch the Sun from “/Rhino Document Sun” to “/Sun Light” (the V-Ray sun) and set the “Turbity” (i.e, quality the air) to 2.0. The dialog box on the right-hand side will change as in the following image.Ĥ. Select the symbol wih horizontal lines on the right-hand size and choose the “sky” 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 “Environment” 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 “sun” symbol is visible as an 3D arrow in the foreground of the “Perspective” view window below.Ģ. 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. Adjust the perspective view similar to an eye-level camera position and horizon line as shown in the “Perspective” view window below. Select OK in the dialog box above and then at the Rhino command prompt note that the default location of “Position ” is indicated. Within the “Sun Angle Calculator”, set the Sun Options to “On”, 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.Īlternatively, as we did in the workshop, select the “Manual Control” method and used the simpler dialog box as shown below to adjust the azimuth and altitude more directly. Next, go to the “V-Ray Lights” panel and select sun control icon to open “Sun Angle Calculator”. Go to non-V-Ray Rhino Render Tab, and toggle off the standard Rhino “sun” symbol. Within Rhino, go to the menu item “Render>Current Renderer>V-Ray for Rhino” to ensure that V-Ray is active. The “sunlight” layer will be used to place a V-Ray sun.
