For example, below is a render of a sphere with a vray light material applied with an intensity of 100. The amount of colour information stored in a full 32-bit floating point file allows you an incredible amount of control in post production. It was developed by ILM for use in-house for their renders, and has been made freely available to all 3D users. A high dynamic range file is capable of holding 32-bits per channel, allowing it to contain a total of 4722366482869645213696 different colours! An OpenEXR file is practically the same as an HDRI file, but it can contain many layers and compression methods. A normal 8-bit per channel jpeg or tiff contains a total of 16.7 million colours (256*256*256). In order to take advantage of this we need to set up V-Ray to save floating point files.īoth OpenEXR and HDRI images are high dynamic range files – capable of holding much more colour information than a monitor can display. This is great for post production as it allows you to change the image exposure without losing any quality.

V-Ray is a full HDRI renderer – producing full high dynamic range images. Add specular bloom to bright areas to enhance realism.Composite them back together using photoshop.Set up the scene in 3ds Max to render out various elements.This can also be applied to After Effects or any other compositing program if you are creating an animation. This tutorial will guide you through the entire process from start to finish of rendering a scene into various passes, and how to composite it back together in Photoshop. There are however few tutorials that show how to do this from start to finish in an efficient way. Rendering out into elements is a fantastic way of having more control over your images and animations in post production.
