Vray is a popular rendering engine that can produce photorealistic images and animations with 3DS Max, a 3D modeling and animation software. Vray 1.5 RC3 is a release candidate version that offers some new features and improvements over the previous versions. In this article, we will show you how to set up Vray 1.5 RC3 for 3DS Max 9 and use it to create stunning renders with high dynamic range imaging (HDRI).
Step 1: Download and Install Vray 1.5 RC3
To download Vray 1.5 RC3, you need to register on the Chaos Group website and request a trial license. You will receive an email with the download link and the license key. You can choose between the 32-bit or the 64-bit version depending on your system. To install Vray 1.5 RC3, you need to run the installer and follow the instructions. You will be asked to enter the license key and select the components you want to install. You can also choose to install Vray as a standalone application or as a plugin for 3DS Max.
Step 2: Configure Vray as the Default Renderer
To use Vray as the default renderer in 3DS Max, you need to open the Render Setup dialog box (shortcut key F10) and go to the Common tab. Scroll down to the Assign Renderer section and choose Vray Adv.1.5 RC3 as the Production renderer and the Material Editor renderer. This will enable you to use Vray materials and settings in your scene.
Step 3: Adjust the Render Settings
To adjust the render settings for Vray, you need to go to the Renderer tab in the Render Setup dialog box. Here you can tweak various parameters that affect the quality and speed of your render. For example, you can change the image sampler, the anti-aliasing filter, the color mapping, the global illumination, etc. For a quick and good render for previewing purposes, you can use these settings:
Image sampler: Adaptive QMC
Min subdivs: 1
Max subdivs: 4
Color mapping: Reinhard
Burn value: 0.8
Sub-pixel mapping: On
Clamp output: On
Affect background: On
Global switches: Default lights On
Indirect illumination: On
Primary bounces: Irradiance map
Secondary bounces: Light cache
Irradiance map settings: Low preset
Light cache settings: Default values
These settings will give you an output something like this:
Step 4: Add an HDRI to the Scene
An HDRI is a high dynamic range image that contains more information about the light and color of a scene than a normal image. An HDRI can be used as an environment map to create realistic lighting and reflections in your scene. To add an HDRI to your scene, you need to go to the Environment section in the Renderer tab and switch on the GI Environment (skylight) override option. Click on None and select VrayHDRI from the Material/Map Browser dialog box.
This will not load any specific HDRI yet, so you need to open the Material Editor (shortcut key M) and drag and drop the VrayHDRI map from the Render Setup dialog box to an empty material slot and choose Instance. This will allow you to edit the HDRI map in the Material Editor and see its effect on your render.
In the Material Editor, click on Browse and load an HDRI of your choice. For this example, we will use an HDRI called Snowfield that shows a snowy landscape with a clear sky. You can ec8f644aee
