Browse Button - Click it and browse for the ies file that you want to use.The main settings for the ies lights are: Then instance it below all four steel holders. Go to the "Lights" tab, choose "Vray" from the drop down list, and create a "Vray ies" in the right view. We as artists can use them to replicate the real life phenomena of light in 3d. Many lighting manufacturers provide web files that model their products, and these are often available on the Internet. A photometric web is a 3D representation of the light intensity distribution of a light source. The photometric data is stored in these files. IES stands for "Illuminating Engineering Society". Increasing the samples will significantly increase your render time. 8-10 should be used for test renders, and 15-20 for final renders. Subdivs - Defines the samples, or the quality of the light.Otherwise it is not visible in the scene. When this option is turned off the source is rendered in the current light color. Invisible - This setting controls whether the shape of the VRay light source is visible in the render result.This is also the light intensity determined by the Intensity units parameter. Multiplier - The multiplier for the light color.The basic parameters of the Vray lights are: Lights 1-4 affect the scene directly, whereas light 5 has been placed in a downward direction, and will affect the scene in an indirect (in the Smaller values make the image darker, while larger values make it brighter. Film Speed (ISO) - Determines the film power (sensitivity).For example, a shutter speed of 1/50 s corresponds to a value of 50 for this parameter. Shutter Speed - The shutter speed (in inverse seconds) for the still photographic camera.White Balance - Allows additional modification of the image output according to the color or preset chosen.Vignetting - When this option is on, the optical vignetting effect of a real-world cameras is simulated.If the Exposure option is checked, changing the f-number will affect the image brightness. f-number - The width of the camera aperture and (indirectly) exposure.Focal Length - Specifies the equivalent focal length of the camera lens.Film Gate - Specifies the horizontal size of the film gate in millimeters.Type - Determines the type of the camera.Step 6Īdd a Vray physical camera to the scene by going to "Create Tab > Camera > Vray > Physical Camera". Now to work on the lighting and render settings to achieve the final result. This is to finalize the lighting and render settings and save time, since a plain material renders much faster than reflective and glossy materials which will be added later. Step 4Īssign a simple Vray material to all the objects in the scene, and set up basic scene lighting and render settings. This will enable "Vray" as your renderer, and also enable Vray materials in your material editor.
Press f10, and from the "assign renderer" tab choose "Vray". Note: It is important that it is a closed room, and there are no openings for the light from environment to enter. just a small lobby (mostly modeled with boxes). Also, as you can see the scene is quite simple. This will play an important role in achieving a good render. When you are trying to get a photorealistic quality it is very important to make sure that your object scale is accurate. In this tutorial, we’ll be using real units, so the first thing would be to open the menu "Customize > Units Setup > US" and choose "Standard > Feet w/Decimal Inches" as the unit. 3D design and modeling services on Envato Studio Step 1 Or you can order from our fantastic menu of 3D design and modeling services on Envato Studio, and have the whole job done for you according to your specifications.
