Screen - This is the simplest sort of background, the kind captured by a simple camera shot.Spherical - Use this if your image is a rectangular unrolling of a sphere.Cubic - Use this if your image looks like an unfolded box.

Next, we need to tell V-Ray how the image geometry relates to the (spherical) environment of the model. Click the blue text to select the appropriate settings (in this case UVWGenEnvironment) Click on it to explore the options.Ī texture such as the one you just loaded can be used as part of a material (a 'channel') or as part of the background (an 'environment'). Read on! The UVW PanelĪt the bottom of the Texture Options dialog are the UVW controls that determine how the flat geometry of the image you loaded is treated in order to make an environment. You have now selected a Texture to use as the background or environment image, but there are a couple of additional details to take care of. If it is a JPG file, it's probably 'Screen Space (sRGB)'. If the file is an HDR or EXR image, be sure the ColorSpace option is 'Rendering Space (Linear)'. This will bring up an OS dialog box to browse for the file. Bitmap is up towards the top-pick it to display the options shown above.Īt the right edge of the Bitmap area, click on the icon to select an image file as a texture image. If it doesn't say 'bitmap' under the image swatch (highlighted in yellow here), click on the word that is there to bring up the texture options list.

When you click on the icon the right panel of the Asset Editor will open to reveal the Texture manipulation options: The check-box ( ) is used to toggle between background color and background texture. If it is a texture, the brightness of the image is controlled by the numeric input field. The background setting may be a simple color (default=black), or a texture (indicated by the icon). In the V-Ray Asset Editor's 'Settings' area look for the 'Environment' options.Ĭlick on 'Environment to expand that section. The environment of the ball is provided by an image of a sunrise, wrapped around the ball and rendered in the reflections and refracted light. The model at right consists of a single glass ball. That is an environment and in V-Ray there are two main ways to do this. You might choose to extend your model to include much or all of this context, but that can get unwieldy, so it might be easier to add that context as a background image instead. The geometry of your model probably has some context: a site, a neighborhood, etc. TAPESTRY: The Art of Representation and Abstraction Rhino + V-Ray: Environments
